I've been watching the tops of my pistons for last 1500 miles since Putting on the Transformer EBS and the 606 and I can tell the black carbon build up is dissipating some because I can see parts of the piston tops I couldn't see with my bore scope before , great video and keep em coming fellas 👍
Wish I would have done this internet stuff years ago , I like that these guys have the resources and time to test their products and videos for my old ass to watch and then get a tested opinion on the very thing I may be pondering about , should have slowed down 30 years ago 😆
Glad you are finding the videos interesting/useful. 👍 Great report on your new set-up and how you're monitoring the results. Thank you for you business, we appreciate it, and it is great to hear how you are enjoying the parts. 👍😎👍
As the carbon layer builds up on piston heads 2 things happen: (1.) some of the volumetric space within the piston chamber at top dead center is reduced causing a slight increase in compression; (2.) the carbon layer has a higher heat capacity than the metal piston head meaning it hangs onto heat energy longer than metal does. This results in slightly more pre-ignition happening on the compression stroke. When this happens: it robs the engine of power and it also damages the cylinder walls where the piston rings and and apron come into contact during the compression stroke. Over a long time more oil gets drawn up past the piston rings into the chamber causing a greater amount of carbon buildup. This increases as the piston rings and the cylinder wall's wear out. One way to combat pre-ignition is to switch to higher octane fuels or use an Octane Booster product added to the premium gas in the gas tank. Sea Foam does work - people have verified this using bore scopes to view the piston heads before and after treatment. However engine wear is inevitable. One way to reduce wear is to allow the engine to warm up BEFORE riding, as the engine gets hotter during warming up makes a tighter seal between the rings and the cylinder walls. Additionally more parts are lubricated. Making frequent Oil changes and using Synthetic Oil also reduces engine wear. Less engine wear = less carbon build up = better performance and greater reliability. On the larger M8 Engines an external breather is a critical piece of equipment to ensure that your Harley will run reliably over a long time - DK Customs makes them. I highly recommend them. Additionally Fueling makes a good vented dipstick which helps reduce blowby by aiding in equalizing the air pressure in the crank case while the engine is running. Both the DK Customs EBS and the Fueling Vented Dipstick are relatively inexpensive and both will increase the reliability of your Harley engine by helping to prevent carbon buildup.
Thank you, good to hear you are finding the videos useful/interesting. 👍😎👍 The thing I learned about common sense, quite a few decades ago, it is Not Very Common. 🙁
After just buying a used 2017 with a TC103 and 7k miles on it I just had to see for myself. Got a good borescope and sure enough the whole top of piston is pretty bad as you shown in video. So now in process of installing a external breather. Thanks
Just ordered an EBS with catch can for an old TC after researching over many months the best solution to vent that crap out of my intake. Now it’s time to clean up the intake and add some SeaFoam to scrub that stuff out of the combustion chamber. You guys rock! Love your videos and the expertise you bring to the community - ride safe!
Thank you for the kind words. Good to hear you're finding the videos useful/interesting. 👍 Thank you for your business, I believe you will be well pleased with the Catch-Can EBS. 👍😎👍
Excellent advice here. My M8 was upgraded to a 124 at 20k miles. Piston tops had a thick buildup of carbon. External catch can set up done then to stop this from happening again.
Good show, I have been using SEA FOAM for cleaning intakes for years with good results. I add a few ounces to the oil before an oil change, it does a deep cleaning of the oil galleries. Cleaning the intake you can let it soak in your favorite cleaner, I also use a soft bristle brush to further the cleaning
I am so glad I watched this particular video. I only have 2000 miles on my 2021 Heritage 114. After plans to install your external breather system this Spring, I thought, "Crap, why did I not know about this sooner?" Good to know the oily plaque will dissipate on it's own. Gives me peace of mind!
I’ve always heard (from unreliable sources) to not spray carb cleaner inside the carb on any sort of engine because it can cause issues with piston rings and the compression seal within and to remove the carb and clean individually and that it doesn’t clean the head enough to justify doing it. I never know what to believe. I just purchased my 1st Harley (2015 Iron 883) and I’m absolutely in love with it, can’t believe it took me this long to get one. Learning how to maintain and service it is a top priority because I just love learning and working on my own stuff and to save money after seeing what the dealer and shops charge for standard services.
Congratulations on your first Harley!!! 👍😎👍 Yes, as noted in the video, I believe best practice is to Not have the combustion chambers ingest any cleaners. (I do believe the listed on the can ratio of Seafoam, into the GAS Tank, not the intake can be beneficial and not do any damage. Carbs are best cleaned Off the bike. EFI Throttle bodies probably also, but a throttle body cleaner, used sparingly to un-gum sensors is something I would not hesitate to do. HOWEVER, the best is to avoid gumming up the intake and the combustion chambers.

I have a 2011 Fatboy and I installed the air intake and the brass breather bolts from DKCustom and a couple of months ago I got me a 2015 Ultra Limited with 43,000 miles and my first mod was the DKCustom air intake at the EBS connected to the small K&N filter. The old OEM filter was very dirty and seems like it was never changed or clean. I will try the Seafoam and see if it helps with the cleaning of the carbon build up.
Congrats on your new ride! 👍👍 Thank you for your business, we appreciate it, and good to hear you are enjoying the benefits. Yeah, the Seafoam will help clean things up.
I bore scoped my twin cam at 35,000mi and it honestly wasn’t too terrible! Still adding an external breather and cleaning what I can. My road glide has mostly interstate miles so that may contribute to the lack of buildup thus far. Going to an AN big sucker intake while I’m there.
Here is a video where we did a dyno run with our 606 Air Cleaner and the Big Sucker. They both use the same Filter element, but the 606 get better horse power and torque than the Big Sucker - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Z2y2-MQrGO8.html The 606 comes with an EBS and our Air Cleaner back plates are made to be compatible with all of our breather kits so you will not need to drill and tap or plug any holes on your backplate.

Thanks for this video. I just bout a 2010 Tri-Glide with 7100 miles on it and was thinking about running some Sea Foam thru it just to be safe. After watching this video of the M8 with 5000 miles, it's a no brainer. I'm also gonna install an external breather. Thanks again.

Long story short, my neighbor had a taxi he was selling, a 1970 something Buick Electra. Car had over 700k miles on it and had never been touched. Pulled the heads off and it looked like new inside. No carbon build up or anything. 1 quart every oil change and a cup in the gas every fill up. I use it on my truck and the wife’s car. Haven’t had the courage to put in one of the bikes yet.
also in the old days we would put a small baby food jar full of AUTOMATIC tranny fluid in the cars gas tank. Helped keep everything clean and lifters lubed.@@DKCustomProducts
You guy’s always put out great info on your videos thanks for sharing your knowledge! I’ve tried about every gas cleaning additive there is and the only two I’ve found to work is Seafoam and Royal Purple and Seafoam has been the best so far.
In the 70,s we use to use a puff bottle with a little water in it & you take the air filter off you just puff a little past the intake while the bike is revving a little .you could see the smoke come out the exhaust .this was a quick decoak on side valves .
Just the info I needed since I just setup an external breather and was wondering how to get the existing crap cleaned out! Harley-Davidson should be ashamed of their stock setup sometimes… 🙄
You can mount all the Aircleaner kits and External breather systems in the world, but if your Valvetrain and Valveguides are screwed it won’t help a damn thing. That’s why a proper warm up of the Engine and Oil is so crucial,.. all the Metal-tolerances has expanded and reached the “operating stage” and now you have less resistance and best fuel burn. But yes,..I also have an external breather system and it undoubtedly helps avoiding carbon buildup. If you are unsure you have a nasty buildup, get a Flex-camera…unscrew the sparkplugs and you stick it down. I have done that many times, and yes I know that some sparkplug holes could be too small…but then maybe you could get an adapter. However,..it’s always interesting to see and follow how much gunk and debris a good old Seafoam treatment can blast out. It IS actually working 👌🏻😉.
that's why some of these guys that have the big bore m8's are having problems they dont warm them up correctly with the 2618 forged pistons and scor the cylinders.
Yes, warm up is important. Back in the carb days, it was easier to wait til they were warmed up, what with the choke (enrichener) sort of keeping you from just hopping on and taking off. Great advice on the external breather and flex-camera. Thanks for the add. 👍😎👍
I did my own external breather 3 brass fittings and fuel line i took a foto of my pistons with a scope then poured an entire can of sea foam in tank after filling up left for sturgis when I got home 4000 miles later much better 1.2 HP better on the Dyno 2012 FLHTC
I haven’t had any success with running it to get rid of carbon. I bought a Endoscope camera on Amazon that connects to my iPhone so I pull the spark plugs and check the build up regularly. What would be a good test for you to do, and post about is taking pistons that have carbon buildup and test what products can dissolve it so it can be sucked out with a bleeder hose. I’m guessing you may have some old pistons you could use.
Why? Why not have no carbon build up to begin with. Time is better spent creating a cleaner engine than keep getting it dirty and spending time looking how to clean over and over again. Here's a video you may find interesting/useful- ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-EfDeFZblMck.html KP
I have been using Seafoam in my cages by adding at every oil change and can feel the difference of smoother idle, throttle tip in response, and transmission shift quality after burning that tank of fuel. I was wondering about using it in the bikes and think I will add some every 4 tanks of fuel. I don't think it will hurt anything.
I cleaned so much blow by out of my intake and inside of my throttle body before installing my EBS then I used Redline fuel system cleaner in my fuel and bike runs so much better.
marvel mystery oil is like a consecrated version of seafome but affordable enough to add 2oz at every fill up and that's how I fight the war against corbin and upper cylinder wear!
I prefer to not have a war on carbon by using an External Breather System. MM is something that may be useful in addition...we have not tested it. But, we may, since so many people have been positive about it.
They both work just as good as the other. If your bike is an older Twin Cam it will spit more than the M8. Having a catch can will contain all the oil and takes cleaning every 5k miles or so. The filter will just be sprayed off when you clean your bike. It is a personal preference as to which will meet your needs. Here is a video where we discuss the differences between the Catch Can and Filter - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-WVZbsLPzmZk.html Please feel free to contact us with any questions; Support@DKCustomProducts.com 662-252-8828 Thank you for commenting! 😎MB
Never had good luck using Seafoam for my injected BMW Classic K. Had to use the stuff with PEA in it, but then went to adding a few ounces of ATF in the tank quite often. For carbon, how about spraying water into the carb at a fast idle? Will that steam clean the combustion chamber and valves?
We suggest using a Throttle Body and Air Intake cleaner to clean the build up off of the pistons or just letting it burn off naturally on its on. Thanks for commenting! MB
I know m8 were having a problem that lead to the external breather but I put one on my big twin and it don't seem like it's doing anything external breather made by fueling
That vent made by fueling is not what we are talking about when we talk about an External Breather System. Check out this video- ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-EfDeFZblMck.html The vent that fueling and some others make is to try and stop the earlier M8's from sumping. Better way to take care of that potential of sumping is to get the newer oil pump from Harley (came out in late 2020) or from fueling.
What motor oils does Kevin suggest for a complete 3 hole oil change on a 2010 Tri Glide 103 cu. in. ? 7500 miles on trike, seems to have noisy top end and loud shifting of gears. THANKS IN ADVANCE.
Hey Edward, there are 3 things to keep in mind when choosing the best oil for you. (1) Run your oil at the correct level. Half way between the add a quart mark and the full mark. (2) Run the correct weight for the lowest ambient temperature you ride in. (3) Do not let your oil get too hot. Once the oil gets over 230° it starts cooking the additives out of the oil. Kevin runs Redline in his engine. He says he uses it because it is the oil that he has found to help the most with top end chatter. He uses Redline ShockProof oil in his transmission. He uses Syn3 in his primary. He says that his clutch has never been smoother since he started using Syn3. Here is a video on oil that we've made that you may find interesting/useful - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-bNHgNThrqQo.html Thank you for commenting! MB
Hey guys! Thanks for the content as always. What do you recommend for my 2016 Dyna Low Rider S w/ the Screamin Eagle breather? Bike only has 2600 miles, and that intake is oily.
Thank you for the comment and question. Glad you're liking the videos. You can either get an air cleaner that is made for an External Breather System, like what is linked here- www.dkcustomproducts.com/air-cleaner-intake-c10-361.htm Or you can add a breather to your SE A/C. Here is a video on how- ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-uAmPC_kglJk.html Here is a link to the different kits available- www.dkcustomproducts.com/diy-external-breather-systems-502.htm
Nice video guys! So i have question about the vents going directly in the ac. If i have the stock ac there is a filterelement between intake and engine breather. Does the filterelemt already helps filter out the nasty oily air? Stay safe
If it is inside your Air Cleaner it is not filtering out the air as much as it can. The breather needs to be outside of the Air Cleaner for the best results. Thanks for commenting! MB
I have a 2019 street glide special with 63k miles. I have never had a problem with her and I don't have an EBS and don't plan to get one. Should I still use Sea Foam every so often? Thanks.
I would do something. Would have to think about it...never considered not running an EBS. Like mln427 says, won't hurt it, but I don't know if there is something better to use if one was to knowingly continue putting that hot, oily, oxygen depleted air into their throttle body and combustion chambers.
I have used Sea Foam periodically, per the instructions, when I've gotten some bad fuel. Never had an issue with my bikes with cats or without cats. Sea Foam Spray is made from 100% safe petroleum cleaning and lubricating ingredients, so it can’t harm sensors, the catalytic converter, or anything else. Sea Foam Spray is used up in the combustion chamber so it’s all vaporized with the hot exhaust as everything is sent toward the tailpipe. Thank you for commenting! MB
That M8 piston was nothing. You should have seen my 2005 Twin Cam after the Harley valve seals failed at 10,571 miles. Since then I have been using a product called Mix-I-Go. Use 1/2oz per 5gallons every tank. Very little carbon. Plus it keeps the injectors clean, removes water in the fuel and helps the octane while stabilizing the fuel. Then I put your breather on and there is even less carbon.
Is this for bikes that ONLY have external breather systems? I have a 07 street glide with 31,000 miles and I noticed a light black puff of smoke during my winter month start ups and I don’t have external breathers
Bikes that have External Breather Systems do not have the oily buildup to be cleaned out that bikes without an EBS get. Bikes that do NOT have an EBS will benefit more from this. You may find this video interesting/useful- ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-EfDeFZblMck.html
Vented dipsticks and transmission cover vents do NOT take the place of the breathers. There is still hot, oily, oxygen depleted air being fed into the intake. The folks that sell vented dipsticks and trans cover vents, have it right in their tech notes that they do not prevent all that crap from going into your intake. The only way to completely eliminate all hot, oily, oxygen depleted air from going into the combustion chambers (thru the throttle body) is with an External Breather System. IF you have an older M8, with the older oil pump and you are concerned about sumping...OR, IF you have a built engine with higher compression, then it may be beneficial to do an EBS And a vented dipstick or trans cover vent.
I use seafoam in my bike. Is there a certain amount you put in the gas tank, or do you just dump the whole bottle in there I've been told different things and I've always wondered.
To tell you what EBS will work with your set up we will need to know what Air Cleaner you have.

I don't grasp the difference between my M8 117's stock breather which is external ad you talking about external breathing systems. Know what I'm saying?
The stock M8 107, 114, and 117 all push the hot, oily, oxygen depleted air thru the throttle body and into the combustion chambers. This reduces power, reduces engine longevity and results in tune instability. Here is a link to a video that explains the difference between your stock breather and an External Breather System- ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-EfDeFZblMck.html
I have a Screaming Eagle large flow air cleaner on my 2015 Road Glide. With this type of air cleaner system, does that mean I have no options to install an (EBS) external breather system????

A friend of mine constant problems with his 1998 Heritage running poor i put a whole can in his tank when he wasn't looking guess what YUP its running much better
What about the piston’s with all the build up that have been running external breather’s ?? There are many on the forums that ran external breather set up’s that still get a lot of carbon build up. I am on the fence about installing the external breather as my 114 does not puke or burn any oil.
I have not seen a *lot* of build up on pistons that run an EBS. If there is build-up, I would be very curious to know what was causing it (gas will not create a lot of build-up) and fix that. Regarding your non-spitting M8, that is great that there is little to no oil. But getting rid of the oil is only one of three reasons to run an EBS. The other two reasons are: -Getting rid of the hot air, engines run better, the cooler the intake air -Getting rid of the oxygen depleted air, the more oxygen in the air, the more power You may find the following video link useful/interesting- ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-EfDeFZblMck.html btw, vented dipsticks and transmission covers are not an EBS, they still let some hot, oily, oxygen depleted air pass into the intake and combustion chambers.
Do you guys have a kit for arleen ness monster sucker? I always see them for the big suckers but didn't know if they have the same backing plate as the monster sucker. Bike is a 15 fxdb.
I am 90% sure that the EBS at the following link will work. But double check with Dwayne or Natalie at the contact info below to make 100% sure. www.dkcustomproducts.com/diy-external-breather-systems-494.htm Contact info: Support@DKCustomProducts.com 662-252-8828
That piston with 5k on it looks more like oil with carbon, I had pistons like that and it was because rings failed and cylinders glazed, if rings sit properly you should have any blow by really
Yes, there is a lot of carbon on there, along with a lot of weight oil that has not yet turned into hard carbon deposits. Agree with you, could definitely come from a variety of causes, out of round cylinders, improperly installed rings (at the factory) are two that are being seen on a larger than normal amount of M8's. There will always be blow-by/crankcase pressure. Even the best built engines are going to see 2-3% get past the rings, which goes into the crankcase, then thru the breather system, and into the intake. Here are a couple of videos that you may find interesting- Why an EBS improves performance- ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-EfDeFZblMck.html Leakdown Test- ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-gojpttZQjKk.html
Curious about that M8 wiht 5000 miles, would you say that's abnormal and maybe he was overfilling oil or something. Cuz it shouldnt be that bad right? Not saying that an EBS is not worth it, I've already ordered mine from DK and should arrive this week. Just curious if you know a little more details about that piston build up.
Yes, that is more than is typically seen on an M8 at 5000 miles. Could have been the way he rode, or could have been the conditions he rode in, or it could have been bad OEM cylinders or faulty piston ring installation at the factory. That said, while it is not typical, it is not rare either. We have seen many like that (not all). M8's have had some problems with rings installed wrong at the factory, they have also had some problems with out of round cylinders. Sorry we do not know more about what the actual root problem with his was. because he replaced cylinders, pistons and rings with a big bore kit. Always feel free to email or call with any questions. We appreciate your business, and I believe you will be well pleased with your EBS. Support@DKCustomProducts.com 662-252-8828
My 2019 had to have a complete top end rebuild with only 13,000 miles on it. Carbon building up was so bad it was making a noise from the piston hitting. The piston rings were installed wrong from the factory. Had to fight like heck to get the extended warranty to pay for it. They said carbon build up is not covered. Wasn’t until I brought up the rings being wrong from the factory that they covered the work. I now have an external breather and vented dip stick. 😢
one of these days they are gonna make a engine system that sprays high pressure rinse in the entire wall of the cylinder and a high prssure vacuum that releases it to the bottom of the bike. squeaky clean engine. probably would make the bike cost 30 grand tho (not while its running or driving, but when its off and it self maintains itself)

I got a question sir, i just bought my first Harley used,well it seems to stall at on tskeoff, kinda poofs though throttle body also could this be my problem to being dirty,?
Seeing old dirty engines having turbos added, still dirty, then adding methanol injection, and everything gets super clean, makes me wonder about jist squirting some in.
Sea foam has nothing on amsoil powerfoam. Had to use powerfoam to remove stuck carbs and clean out jets and bowls in old rx7 carbs with gunned up premixed fuel. It stinks like mad but just try it.
Best to never build up any carbon by using an EBS from day one. Even if one has carbon build up, Ride It, it will burn off. But sometimes, on a used ride, it is unavoidable. Glad you are liking your powerfoam. 👍
I had soaked the Nikki carb in sea foam first because I knew it was a good product. However using a qtip to clean down inside the bowls just led to a gummy mess. The old premix and varnished fuel literally was gluing the throttle shut - I thought I was going to break the throttle cable! Powerfoam did it’s thing, and it rinsed out with hot water. I’d highly recommend trying it out to clean an ethanol clogged carb or anything that’s been setting for a long time.
I have a 2022 SgS and took off the stock air intake. I went with the Arlen Ness 90 Degree Monster Sucker. I noticed that I no longer have the tubes that came off the engine heads that would redirect the oil back into the air intake. Where is this oil going now. Also now that I don't have the hoses to do that, am I going to cause an issue for the bike?
With the Arlen Ness 90° Monster Sucker from what I can tell the hot oily oxygen depleted air is going back into the intake. We do have a DIY external breather kit you can use with Air Cleaner, but it does mean drilling into the stand offs and tapping them and routing the hose from there.

It depends on what year and model bike you have. If it is an M8, no retune is needed. If it is a Sportster or Twin Cam and still has the OEM tune, it needs to be richened up, even if not adding an EBS and free flowing air cleaner. If it is a Sportster or Twin Cam and already has a free flowing air cleaner, and already has a good tune, then you should be good to go.

@@DKCustomProducts my local shop is about 15 mile from me will it hurt the engine if i do the EBS and high flo air filter then ride it to the shop to get retuned?
It does Not. Only an External Breather System, like seen in the link below, completely eliminate all hot, oily, oxygen depleted air from going into the combustion chambers. www.dkcustomproducts.com/breather-systems-c21.htm Vented dipsticks and transmission cover vents do NOT take the place of the breathers. There is still hot, oily, oxygen depleted air being fed into the intake. The folks that sell vented dipsticks and trans cover vents, have it right in their product description that they do not prevent all that crap from going into your intake. Here is a copy and paste from the Trask website- "This will reduce the oil exiting from the head breathers..." IF you have an older M8, with the older oil pump and you are concerned about sumping...OR, IF you have a built engine with higher compression, then it may be beneficial to do an EBS And a vented dipstick or trans cover vent.
Yes, once you have an External Breather System installed, a lot of guys like the Marvel Mystery Oil. It has been decades since I used any. I cannot speak to whether it removes build up or not. Thank you for commenting! KP
Some folks use a borescope hooked up to their phone. Fairly inexpensive, and interesting to look. Here is a link to a written report that you may find interesting, plenty or photos and some videos that you may find useful. www.dkcustomproducts.com/overview-of-external-breather-systems-ebs.htm
Back when lead was on the gas we would just put a trickle of water down the carb throat of old cars. On a bike I would suggest just a spray bottle to squirt some water in......steam will break up the carbon......you will see it come out the tailpipe.
If you get all that hot oily oxygen depleted air out of your intake the carbon build up will stop and eventually burn off on its on. Yes there are lots of ways to clean the carbon off this was just a video about how we clean it off and how we suggest that it be cleaned off. Thank you for commenting! 👍 MB
Wow, sorry you have not had good experience with it. It has been very helpful to me on quite a few occasions. To further my knowledge base, can you share what your dealings were with seafoam? Thanks. 🏍
@@DKCustomProducts sure, I have a 1982 Honda goldwing aspencade and filled the carburetors with seafoam, the bike set for a while because I had some medical problems, I thought that'll be fine it'll just do a better job cleaning the carburetors, finally when getting back to the bike, I had to drain the crabs four or five times after filling them with gasoline. I finally got the bike started up and had to learn across the bike to get to the throttle and the bike was running very badly, I looked down at the muffler and it was cherry red, I switched off the bike and cooled it down with a fan . It ended up at a shop so I go to the shop when the carbs are dismantled and I was asked have you been running either (not sure about the spelling of that) the diagrams in the carburetors was kinda like tar. I guess I left the seafoam in to long. My bike is a Honda and a bike over 10 years old the Honda shops won't touch them. I guess I was lucky to find that shop. Anyway, after getting everything on the bike fixed or replaced I spent something like $4,100.00 on it and I did have to get the muffler recromed. The bike is in mint condition and right now if I could ride, I wouldn't be afraid to ride to California. I think the carburetors were probably about $1,000.00 to be rebuilt. Anyways, I really don't have anything against seafoam, I'm just afraid of it.
Yep, I was taught to do that over half a century ago...and a lot of folks (most) do it with zero issues. Over the years I have seen only a couple that had a piece of carbon break loose and mess up a valve seat. My preference is to not have any build up to have to clean up. 👍 You may find this video useful/interesting- ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-EfDeFZblMck.html
Because that is how crankcase pressure is vented. If you plug them you will blow seals and/or gaskets. What you can, and should do, is get an EBS that stops that hot, oily, oxygen depleted air from routing into your intake. Here is a video on the subject you you may find useful- ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-EfDeFZblMck.html
Yeah, I've seen a few vids and articles too. They never offer any proof, and just talk about what they like or what they think. Whereas, I have actually experienced the benefits of using it, and have seen many videos and reports where folks show the beneficial results. Regarding breaking up carbon deposits on the pistons or in the throttle body....as stated in the video, better to use an EBS from the get go, but if you don't, just riding will eventually get rid of most of them, and if you want to speed it up, then use sea foam. For getting a bad tank of gas, it works Great!
How not to get carbon = venting crankcase vapors to atmosphere not the intake. That also phuques up MANY thousands of car and truck intake manifold passages where the goo bakes into sludge. HD crankcase venting problems were solved before WWII and dumping oily vapor into a perfectly good combustion chamber just inflicts what piston rings and valve seals exist to prevent.
Yep, it is crazy how government agencies think they are reducing pollution by venting internally, when all it does it make things wear out prematurely, AND makes for worse MPG. So more parts have to be made (which causes more pollution than is saved from venting internally.) Here is a video on the subject- ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-EfDeFZblMck.html
What do you think will happen? I have used Sea Foam periodically, per the instructions, when I've gotten some bad fuel. Never had an issue with my bikes with cats or without cats. Sea Foam Spray is made from 100% safe petroleum cleaning and lubricating ingredients, so it can’t harm sensors, the catalytic converter, or anything else. Sea Foam Spray is used up in the combustion chamber so it’s all vaporized with the hot exhaust as everything is sent toward the tailpipe.
