How to install a Jet Kit Honda VT750  

I used this video 7 years ago to install a jet kit in my Shadow 750. Now I'm back and doing a rebuild on that same bike, as it's developed a massive lean condition at high RPM. As an instructor in many topics myself, this is a great example of how to teach. Thanks for sharing such great info with us!

Great video, and very informative and helpful. Fun fact for gear heads: Japan uses JIS (Japanese Industrial Standard) which looks similar to Philips, but there are fitment differences between the bits -- which is why those screws were hard to get out. Philips head screwdriver with JIS screws. It's a sloppy fit.

I just want to say thanks for taking the time to make this video. Great video and great explanation!!!

this instructor did an amazing job in explaining every detail and made absolutely sure everyone understood by asking all the right questions. great video!

Talk about thorough, this guy pays such great attention to detail, when wrehcing on motorcycles it SO incredibly important to ensure things, especially carburator are set to spec and inspected properly as well, you can do everything right and have one small thing that you made a mistake on and the bike will not ride properly, to be a great mechanic you pay pay special attention to detail and take no shorts. These are great video series

I completely agree, this is a great video and clearly these apprentices are learning from a great tuner!

This guy is a fantastic instructor! Well done, sir.

GREAT video- I'll be watching it again when I pull the carbs from mine. It sat for three years and has issues. Backfires when attempting to rev and won't reach higher RPM. Just to make it fun, figured I'd install a jet kit during the clean/rebuild. EXTREMELY well done and you are a VERY good at being an instructor.

Great video. Im a old school automotive mechanic and have done hundreds of car carbs. And also have done my personal motorcycle carbs. This video is very very good. covered everything. Helped me very much.

Good little video and class. Also the Shadow 750 is a very little known/underestimated performer. In stock trim we see them make around 38-40 HP at the rear tire. This is far from exhilarating but can be easily increased. A set of good 2" drag pipes or 2 1/4" cruiser pipes, simple modification of the stock air box (Google "BeanBox mod") and Stage 2 jet kit will yield 43-45 HP at the wheel and is a VERY noticeable difference on a 500lb machine, especially since power is up everywhere from 2800-6200 RPM vs stock. This puts the VT750 Shadow square in the 1/4 mile territory of HD Sportsters, Yamaha Bolt, Sabre/Shadow 1100 etc with mid 14 second passes being the norm. If you want to take it further, JE produces 10:1, 10.5:1, 11:1,11.5:1 & 12:1 Pistons for our Shadow factory bore sIze. (11-11.5:1 is about ideal for 93 pump gas) At the time of adding new pistons, take the time to smooth the intake ports/runners on the stock heads. (Remove any/all casting flaws) After re-assembly, do the "4* timing mod", go up one step colder than factory for the spark plugs, and re-jet the carb again. (This time individual jets will need to be ordered, not a kit) It is also reccomendsd at this time to go with a "Hyper Charger" type of airbox or an open element K&N style filter for maximum flow. I personally switched to a single carb setup ala the 2006 Aero model, just to make tuning the bike easier. When all is said and done you end up with a lightweight and nimble Honda Shadow with over 60 HP at the rear tire and an incredible power curve. Total cost if you can do the work yourself is about $1500, pipes included. After this newfound power a sprocket change will be the next logical step, Aero owners will not see the most gains unfortunately due to shaft final drive. For those people just put some good hypoid gear oil in your shaft housing and call it good! For the Spirit and other chain driven guys, add that new power to the proper gearing and you can see 12.9x quarter mile ETs in the 110-112 MPH range with a 1.8x 60ft on stock Aero tire sizes (120/160 F/R) It's about as fast as I would want to go on such a small, low riding cruiser! Cheers to the Shadow!

I just bought a similar bike. Lots of great advice in your video. Thank you so much.

Excellent video! Thank you!

thank you sir for all your work!

Thank you so much awesome video Going to dig into my 07 shadow to re jet it for intake + Drag pipes. this video helps very much

Excellent video my friend. Very informative, very clear and well presented. Thank you.

This is an amazing video. I'm going to be doing this on a 2006 VT1100C this weekend and I'm sure watching this has already helped me a ton. The vacuum slide tip in particular I wouldn't have known since it's not in the manual.

A screwdriver stocket on a 3/8 drive is my favorite way to break stubborn screws lose. Works every time!

Great video!

Great video 👍 Lots of nice pro tips. Always wondered what those carbs looked like when they're clean and not beat up

Excellent vid thanks

Wow! What a video. This is what RU-vid is for, I bet Troy is happy ;) I've got an Aero - single carb, so it's even easier. Might even give this a go myself. Thanks for uploading.

Good stuff thanks

thank you so much for defining which carb is front and which is in back. realized I jetted mine backwards, maybe this is why I am having power loss

I have a tic disorder, I can tell he might be struggling with it too, this dudes awesome, it's always good to not point out what's "wrong"with people, super self cautious about it

I somehow was logged under a co-worker on prior comments, johncapps. I was interested in if your classes are for the open public or if you had classes for us? love the detail that you explain with every step you take! great job, just subscribed.

I've been watching your videos. your are a great instructor. I feel I must share a story with you, I wish every dealership hired good mechanic. I had Honda install my jet kit when I customized my vt750c shadow aero. after the bike sitting for two years I am getting it ready for the road again I pulled the carburetor to clean it out and found countersink screws in place of a Machine screw. can you believe that. and the chock. mount was broken and glued back together witch had now failed. so after hundreds of dollars later to fix the factory's mess up its working great now. I wish the 500 lb Gorilla never touched my shadow aero . keep up the good work

Just got me a VT1100 video gave me confidence to work it, thanks. Btw i do have a fuel leak on one of the hoses that comes out from the small cylinder (air valve i think it is) that connects to the right side of the carb any ideas what could be causing the strong leak???

Great video, and my comments are all similar to those below...

This is an amazing video, thank you so much! I've been trying to find a good tutorial on this and honestly I feel like I was in that class! My only question would be if you could use this same kit, but with small changes for other configurations of the bike. Like a different air intake for example. Again, thank you so much, this is amazing!

9:42 Even if you use JIS screwdriver and screw is seized, use "snapon 5acp pliers" to break it loose; also look into maybe a vampliers equivalent; some people take float bowl screws down to hardware store and replace w/ allen heads also;

I did substantial hands on jetting to a 2003 spirit. The smaller main jet goes in the rear as that cylinder gets hotter and thus, less dense air....also, the Dyno-jet needles were way-too aggressive in taper. i used the stock honda needles and the bike ran like a top from idle to full-on in 5th gear a whopping 126mph. great class to take and good teacher.

I’d really appreciate the response, there’s so many differing opinions online, to get it directly from a professional would be an amazing thing.

play a drinking game and take a drink every time this guy fucks with his shirt...lmao...

Just the video I needed. Where are more for this 750 carb?

loved that class and I live here in Iowa. is that open to the public or only for students? I'm self teaching myself and LOVED the detail that you presented to the class. thank you.

Excellent video(s) Shane. While taking off the slide cap, I noticed your advice on the phillips screw fastener, risk of stripping, and the ACP pliers. I ordered some JIS screwdrivers (from Japan) to fit these "phillips" screws, and have WAY more success at not stripping these Japanese screws. The JIS screws are actually Japanese Industrial Standard screws, a significantly different head pitch than the American Phillipsm, which leads to stripping the socket mating surface. Some techs grind the tip of their Phillips screwdriver to better seat into the JIS screw head, but still isn't the right taper, etc. The JIS screws usually have one dot on the head helping identify them as JIS. You may have covered this in later videos, but is something I just learned this year for all these Japanese made bikes. Check it out!! This is why many techs will replace these with socket head screws, when it was due to incorrect tool fitment!! Snap on, Mac, etc don't have them, and probably won't even know what you are asking for!! Again, great training(s). Thanks!!! 6-12-16

What is the most crucial step that must be followed thoroughly when you take apart Carb? I think my carb is about to die. Thanks

I'd do one carb at a time instead of worrying about which one is front and which one is rear throughout the rebuild and replace float bowl screws with allen head screws

Great video. Very good explanation. Question!- is the needles actually different ?

Hey boss, I have an 05 shadow spirit 750dcb, same exact carbs, but I can’t find the dynojet kit you used , where would I source the same kit?

i cant find the oring that goes around the inside, i have a shadow 750c2 single carb its the bottom piece of the carb (where it opens to the jets) anyone know where i can find it/or the part number thank you!

Float pin and float height at 32-34

The reason you were in danger of "stripping" - aka ruining the head on - those carb screws was that you are using the wrong screwdrivers. Japanese bikes (and electronic equipment) commonly use JIS screws. With JIS screwdrivers you can feel the driver lock into the cross slot on the screw while a conventional Phillips driver will not seat properly in the JIS screw. You can feel it wobble and you risk ripping up the slots on the screw. Btw, JIS screws can often be identified by a dot on the head next to the cross slots.

Hi. I am just wondering if you have a video that shows how to remove the carburetor for a Honda Shadow VT750 Spirit 2002. Thank you for your great videos.

For me, one question isn't answered - but very important - in the beginning. If there is an aftermarket exhaust with baffles and original airbox with aftermarket airfilter (k&n), is there still the use of 102 (front) and 104 (rear) or should 104 (front) and 106 (rear) be used because of the air increase of the k&n. He said that the question of using the stock airfilter is important but not why or what would be the difference in setting up the jet-kit 😢

Is this doable on a 125cc carb motorcycle?

hello shane, you mentioned about removing the fuel screens behind the needle/seat. What benefit would that give?

Why didn't you use a tap on the screw? Give it some love by tapping on it. 13:30 now I know why does my moto is not running. I mixed them up while putting them back together. I didn't know that there are differences in jets size jezzzz. How should I separate the front jets from rear ones?

Hey can you make a video on how to reinstall the carb back into the bike? I don’t understand the manual at all with what tube connects to what on the carb.

Do you recommend Dynojet or Vance & Hines jet kits for the 2003 Honda VT750CD Shadow ACE? I'm also installing the Vance & Hines Cruzers 31641 pipes just like your student has on his motorcycle. Notice you were using the Dynojet kit in your video, but there was no mention of why. Cheers

do you have clases online?

What stage jet kit would I need for a 2000 Honda shadow 1100 with straight pipes, stock intake with K&N at 6,000 feet above sea level?

@Shane Conely around 6:06 in your video, you reference “part fish”, what is that resource exactly? Thanks

I have a 2003 Shadow 750 ACE that I bought and it already had Cobra drag pipes on it. I'm not sure if the carbs were re-jetted or not. How could I tell? The bike does not seem to hesitate at all but it does have popping sounds on closed throttle deceleration (engine braking). There is no popping or backfiring otherwise. Any way I can tell?

Hi there. How much is that Jet Kit? Thanks for the video. You are excellent!On those small pliers; they cost $36.00 at Snap-on dude! No way. I'd go to Auto Zone to get'em.

Where can I find the video on bench testing? I am so close to resurrecting a 1984 Vt500FT Ascot if I can just get the carbs to behave!

have a look in to JIS screwdrivers.

i have a question that maybe you can help me with, I own this same bike and i removed the back baffles out of the stock pipes, it didnt do it right away but i am starting to get backfire and popping and smoke coming out out the pipes just recently. the bike has no problem starting, it doesnt pop unles i rev the throttle, what should i do?

Does this carburetor have an accelerator pump???

His ticks are interesting

was that a stage 7 kit because it says on the bottom of package " for racing use only"?

is it possible to install a 6sigma jet kit on a 100 cc pocket bike?

No Brasil não consegui esse kit

i was hoping he was going to talk about the different stages a little more

Where is the best place to buy the dynojet kit?

What would a guy have to do if he did have an aftermarket intake?

I have a 99 Honda Shadow 750 I rebuilt the carburetor change the fuel pump my bike goes down the road guys like runs out of gas what did I mess up what can I check in 60 years old it's been 3 years I want to ride help me I can't take it to the shop money's tight😢😢😢

So smaller jet in front cylinder carb and bigger jet in rear cylinder carb for temp difference. Gotcha.

Just use non-ethanol gas

actually you aren't using the right screwdriver.... you need to use PZ screwdrivers instead of Philips.

way to show float adjustment..........NOT
