Took off the carb on my new to me 2000 cyclone. irregular idle now and hangs with a little throttle. I put some propane to the carb/manifold rubber and the idle went up. This is my first vtwin so I'm wondering if theres a trick to sealing this carb to the manifold, or if i need a new seal.

Sorry for the question without introduction but first things first i gotta get this thing ready for inspection

usually a good idea to replace the seal every time you remove the carb. the second good tip is to polish the surfaces that mate to the rubber, to make sure you get a good airtight seal.

Use Sylglide also. On both the boot and the intake seals.
Replace all three to save headaches later.

Probably a dumb question, but since the bike is new to you, did you put the carb mount back on the front of the carb before you fired it up? There is nothing physically retaining the carb except friction unless the carb mount is bolted to the carb and the heads of the bike.

Good idea Bluz. It is very good for rubber parts. It is called Sil-Glyde and made by American Grease Stick Company and I have been using it for over 35 years. Including many more uses.

BUELLers:


INTAKE SEALS 101

"i" live in Florida, therefore how long the intake seals lasts depends on where you live ...

Before "i" installed a cooling fan, "i" replaced the seals every 2 years ...

Just replaced these seals at 4 years and they were still good, next replacement will be at 5 years ...

My way, is spray seals with silicone, assemble finger tight, and evenly torque to minimum spec. ...

Replaced my allen screws with hex bolts which "i" safety wire ...

MAY THE LONG LASTING BUELL BE WITH YOU !!!

Thanks for the sil glide idea, thats what i was looking for. The local dealer has the part on stock so not a big deal. Ill replace and add sil glide.

Yes the bracket held by both cylinder blowouts (carb mount) was reinstalled.

Thanks for the ideas. This seems to be the better site for buell forums.

Now any idea where to find a parts fiche online?

Out mean a Buell parts cache? His name is Wilson... He is the largest LOL. Anyone of the other Buellers here who have multiple tubers generally have a large enough cache to put another bike together...

1) Why did you take the carb off?
2) What did you do to it?
3) Why?
Put a Mikuni on. It will fix everything you broke.

Psyclown, go to American Sport Bike for your tuber needs. Rebuild the carb! If it has never been rebuilt then that rubber is shot. I usually have to do this every 5 years and what Bluzm2 said as well. Check your throttle and idle cables and make sure they are moving freely.

parts fiche, ha ha, you must be an old timer. Fiche went the way of the floppy disk, the big 5 1/4 ones. Parts book for your model is the best bet. The dealer only has computer terminals now, and the 19-year old kid behind it may have never even ridden a tuber, in fact may or may not know what you mean if you say the literal appellation 'tuber'.

Seal replacement is a good 'break-in' for a new owner. You'll find out which tools you're missing!

If you ordered a new Forcewinder, look into the vent bowl mod because you'll need it. It will make a difference!

The white rectangle indicates what the stock float bowl vent looked like, you have to open it out for proper venting.

There are better pics in the Knowledge Vault

While you have it off, you might as well take some 220 and 400 grit sandpaper to the inside of the elbow of that forcewinder and clean it up a bit. It may not be a huge difference, but it can't hurt. I did that to mine and will do the same to my intake manifold when I replace intake seals.
