WATCH THIS BEFORE YOU SEAFOAM A GOLD WING GL1800 AND POSSIBLY OTHER MOTORCYCLES 

I fought the dreaded hesitation for 2 years on my 2008 Gl1800. I tried several bottles of seafoam, it seemed to help but did not cure it. I ran across an obscure post on a forum about the hesitation, he claimed to fix it. There was no other discussion about the fix he had explained. It was time for an air filter so while I had the shelter off I did what he recommended, it cured it. If you look closely down the bore of your throttle body where the butterfly plate seats on the sides of the bore at idle, you will see a faint dirty mark from the throttle plate. Take a toothbrush soaked with seafoam and lightly scrub that mark off the bore and the plate clean. It fixed it completely. I've got about 8K on it since then and still running perfect. Mine was so bad it was difficult to do any slow speed maneuvers in a stone parking lot without slipping the clutch drastically. Next time you do an air filter, check it out. You must look closely to see it, at first I didn't, then I got a light and I could see a dirt mark.

I appreciate what you told us about the sea foam. I just bought a 1998 1500 with 18,000 and right away I changed the oil. I then noticed I had a hesitation and knew it was from sitting so long. Also, I owned three 1800's and they all had that pan under the motor and its to keep rocks from ponding the lower part of the motor.

So I am getting ready to SeaFoam my Valkyrie. Suggesting changing the oil afterwards seems like common sense, but I honestly had not considered it. I’m pretty happy about watching this video. Super happy you shared this. Big gut punch though, I just changed my oil and I run Amsoil. So this is gonna be expensive…worth it, but expensive lol Good Job on the video

Conventional oil disapates heat better while synthetic superior slickness reduces friction. I use Honda synthetic blend. My engine runs cool and oil change intervals once every season is clean. The pan protects the motor from road debris definitely leave it on. Yes many bikes don't have that protection. Great video seafoam is a great product and can be added to oil right before oil change. Good call on dumping the oil right after treatment.

In to addition road debris protection some of the Wings have fore and aft ridges under there that can act as wings in a severe crosswind, leading to bad handling. The belly pan blocks those cross winds. Or so I read before I got mine! 1995 GL1500, Mobile1, once a season ( even for 10-12,000 miles. But it is almost all high miles, and very little in town. )

That is a after market skid pan. We use sefome in our shop also but don't ever put more than 1/4 bottle well the top of your pistons and valves are clean. We have been working on goldwings since 1975 we have great results with ams best viscosity will not lose more than 5%. Have bikes we work on with over 289000 miles on ams. One of those people is a imploye. Good video have a great day. Pops

Great info on the oil. I have heard about the sea foam treatment but nothing about changing the oil after adding sea foam to the fuel.

Be thankful you have that metal guard covering the bottom of your engine Mo, it is to prevent objects from being thrown up from the surface of the road and going through your engine cases.

Wow great advice Mo!

I really enjoy watching your videos!

The small pan works just like the belly pan. It is there to protect the underside from rocks etc. I have a Goldwing GL 1500 SE (1994). Hope this helped

Great video Mo! Thanks for sharing.

Great tip! Sea foam really helps clean both the fuel and engine!

I just did a seafoam in both the gas and the engine oil. Drove it about 180 miles and changed the oil this weekend. I have yet to see what driving is like as I took off my wheels to get new tires put on and now have to replace the brake pads. The oil was only because I don't know exactly what the previous owner did. I know he was a sheriff and evidently did a lot of off duty work so maybe a lot of slow maneuvering, so I just wanted to make sure the clutch plates were clean. The oil was pretty dang dirty.

I put seafoam in my 1800 about 2 ounces in tank about every 5 fill ups ,Half a can would be enough for about 20 gallons of fuell ,That much may affect oil ,I've not had dirty oil from the process I do

I had the same problem on my 2012… that slow speed hesitation… my fix was to get a G2 throttle tamer… the plastic oem throttle tube from Honda is crap… the G2 smoothed that hesitation right out… so no sea foam was needed 😊also what helped was to get the wide clutch lever from Show Chrome… better control at slow speeds using the friction zone 👍

Pans are aftermarket item. I use the valvoline full syn in my wing. Told the dealer that .... he was agast that i wasnt using honda lube. He even dared to say regular dinosaur honda oil was better. I just smiled and said thanks for your opinion.

I plan on doing this treatment on mine. Just changed the oil so think I'll wait a bit. Like you said the oil turns dark quickly. I am using non friction additive synthetic mobile 1. I also was surprised how expensive the filter was too. Made in China. Factory filter from Honda dealer as I prefer Honda only. Great video Sir!

I used Shell Rottella T4 Conventional 15w40 in my Yamaha yx600. 14 bucks for 4 quarts. They have T6 which is the same weight but fully synthetic. Little more in price but lower than buying "motorcycle oil". its also got a lot of stuff to keep low miles motors running longer and keeping them clean. Same with older motors with zink and such.

nice.....good call, good tip

I acquired a oil test machine at a sportsman show. I've tested all popular oils over the years an found "Castrol" oil out performs other oils, not by much, but still out performs!

Thank you for those tips

I’m only asking because maybe I’m not getting what you’re saying, but adding anything into your fuel tank should not result in that getting into your engine oil, if it did then surely your fuel would always leak into your oil?? And if so then surely your oil could leak into your combustion chamber and you’d be burning smoke the whole time your engine is running ?? Maybe I’m 100% wring but that would be my understanding ?

My 1500 had been sitting a couple of years before I got it and stumbled at low throttle plus the gas was nasty. Tossed the old gas and filled it with 93 and a whole bottle of Seafoam. By half a tank, no more stumble. Oil was who knows how old so fresh oil and filter along with 4 oz. of Seafoam. After 300 miles it was filthy so it got changed with Mobile 1 again. About 500 miles now and it's getting dark again. Seafoam loosens the crud and a good oil flushes it out of passages and crevices. It ain't cheap but oil is cheaper than steel.

after market skid plate damage protection for engine case sir

Thanks for your video, so if I got you right, you only put sea foam in your gas tank right, not in your oil refill. ?

I swear by SeaFoam. After I bought my other bike (Suzuki Boulevard C90T 1500cc), I ran SeaFoam through it and my mileage shot up significantly. I got over 50 MPG after running SeaFoam through it. It didn't stay that high, but still stayed in the mid-40 for miles per gallon. I'm not going to complain about that at all.

The cover is to protect the drive shaft from hitting the highy and flipping you over the handle bars

Never gave this a thought. I pored the entire can of seafoam in my St1300. Have done this 3 times in the last year and half......not sure if it really helped but I felt better...

I know this is late but I can see the oil being black if you added sea foam to the oil but you added it to the gas????

I use seafoam for storage only seems to work fine on my GL1500 never ever thought about the deposit thing BUT i only put a small amount Half a can seems like a lot for gallons!

Mo, The belly pan was used on 1500's so the side covers would not blow off. They also help on the freeway when passing a semi. keeps the bike more stable. the front part of the belly pan is held on by aircraft screws so it was easy to remove it to get at the oil filter.

How long did you run with the sea foamin the bike?

Night at the Goldwing!!!!!!!!

Well if you want to use the best on that sweet wing , use Amsoil oil and filter. 💪🏼👍🏼😃

Yes sir they are belly pans. They stop anything you might hit on the road to avoid cracking the aluminum block

The dealer told me if you’re going from the regular mineral oil that is started out with an all gold wings, OEM oil and you go to synthetic you are likely to develop oil leaks because of the molecular size of the mineral oil is larger than the synthetic oil and therefore it will penetrate those all the gaskets and stuff and eventually cause oil leaks. So I stayed with the OEM Honda oil. Have you on the bike since it was new and used synthetic always? I just bought this 2005 and it only had 27,000 miles and it is always been serviced by the dealer so it always had that OEM oil.

Mo, be very careful with the Seafoam in your fuel system. It dries out rubber. So you increase the chances of fuel line failure from the inside of the lines. I'd think once would be fine.

I think you should be using 10w30. The make of oil isn't important as long as its reputable

How do you cure the idle lope?

Bellie pan! Keep it!

How can fuel additive affect your oil?

So the seafoam in the gas, watered down the oil?

Instructions read 1 ounce per 1 quart of oil. Run 100-300 miles then change oil and filter.

Man I love your painted dash, iv never heard of seafoam, what does it do? Clean out bikes fuel system? Alaways worries me putting stuff in fuel tank 🇬🇧👍

I was getting FI code 26. Left Knock Sensor. Poured some Seafoam and revved the hell out of it and I haven't seen code again.

It’s called a belly pan

Half a bottle? I use it according to directions on my 93 Goldwing.....with 117k miles.

Could it be possible that the sea foam created excessive wear on your motor and that's why it's so dirty?

Wait, you just added the SeaFoam to your gasoline and got it that black? Wow!! And you didn't add Seafoam to your crankcase oil 100 miles before the oil change like SeaFoam suggests to clean the inside of the engine. I've used SeaFoam in the gas tank to clean the fuel system and injectors.

You are holding the oil bottle upside down. Look at the image on the bottle. The spout should be held at the top to minimize spilling

Are you still using Castrol oil?

Again sorry,, did you put some into your engine too,?

Knew a guy used seafoam screwed up his diaphragms in the carb, don’t know how much he used though.

full synthetic is only 51% synthetic and 49% dino oil. AmsOil has a 100% synthetic.

A

I dont believe seafoam would have anything to do with dirty oil, gas burns in the combustion chamber above the oil, they dont really mix together unless you have very worn rings.. Most oil will be black after 1000 miles anyway.

Pay Attention People. DO NOT PUT SYNTHETIC OIL IN A WING !!! Here's why,. The transmission and engine share oil. The slicker synthetic oil is BAD for the friction surfaces on the clutch discs. The discs will slip as they mate or come together under load. This causes more wear and heat than necessary. Thus shorter life for your clutch. Don't take my word for it. READ your manual. See what HONDA RECOMMENDS.

Your a little behind Homer, that info has been around for a long time.

Hahahahaha. Sea foam. HahahahH

That oil is tar, The sea foams will clean everything but it sure causes the oil to get hot to turn so thick, I run B 12 in my GW and my oil stays new, The slides get sticky and not let them move as smooth till I put in B 12, about a glass full per tank should do the trick. Would double cheek with Honda on New bikes before you use it in Your tank and how munch

And it keeps vampires away!!!!

im so confused is that a body washer? wtf is sea foam? fuel injection cleaner....do u put A1 steak sauce on a prime ribey steak? come on

Unbelievable. They’ll let anybody put anything on with no accountability. Clown

Why not put some atf in the engine oil to clean that. Hahahaha. And use blinker fluid in your brake master cylinder. Hahaha

Oh so sea foam made your oil thick and black. Ok. Yep. Any and all credibility has been blow out the window!!! From sea foam. Hahahah.

I don't use anything else but what the bike calls for, this cheap fixing is going to cost you money.
