Hey dudes, can I get your help with motorcycles again? :)

TITTIES AND BEER, TITTIES AND BEER, TITTES AND BE-- oh hi there.

So I just bought my first bike about two (three?) days ago. There's just one problem:

It has a really *REALLY* high idle speed. It idles at about 5000RPM when the engine is disengaged (i.e. clutch in or in neutral); however, when I start riding the RPM's are normal. I've tried messing with the choke, the idle screw, made sure the throttle cable cleared to the carburetor correctly - which it did - and made sure the choke cable cleared correctly - which it did too. So now I'm down to a hole in the vacuum tubes (I don't even know what those are[ROFL1]), disconnected vacuum tubes, hole in the intake manifold, something screwy with the clutch cable, or possible carb adjustment. Anybody else have any ideas?

Here are some pictures if it helps! Don't worry about the fluid spots on the ground, that's just from changing the oil. And if some a$$wad says "you're having problems 'cuz your gas tank is missing" well, I dunno, I'll fart in your general direction! [Coffee] I took off the side fairings and the gas tank to get a better look at all the inner workings. Anyway, I'd really appreciate any advice you guys could offer! [Beer] First time working on a bike, and I feel like an idiot! [Tooth] *a-hilk*



__Here's a hole I found, the tube that connects to this plastic canister connects to a big black plastic thingy I found under the gas tank.

___Is there supposed to be a tube connecting to this? The spout (circled red) is on the air intake.

___Is this supposed to be only connected to the big black thingy I found under the gas tank?

___These were connected to the gas tank, and I assume it's normal for them to be hanging down. But, what is their function?

____Last but not least, what is that black housing for? The thermostat? I had some coolant leaking out of there when the engine warmed up, so I'm guessing that's what it is.

Well if you guys could help me out I'd really appreciate it. I'm kinda stuck in a mire here...and I have "Bicycle Race" stuck in my head.. [ROFL1]

What is the year/make/model? From those pics it looks like a sport bike. On most sport bikes there is an idle adjuster on the left side just below the seat. Turn it counter clockwise to decrease the idle.

Try that and let us know if it works.

Go to TFOG, I highly recommend him. He is also a member on here TFOGGER is his screen name. They do great work and he treats other members very good. He is off 6Th ave and indiana

Liquid drain for the air box. just a hole for any rain that gets sucked in.

Drain tubes, one should connect to the radiator overflow, one should go to the pan around the gas cap (incase of overfill) etc OH and your idle adjustment knob can be seen in this pic.

Your questions need a bike model, and more specifics. There's 3 black housings in the pic asking what the black housing is. The one with the large tube coming to it is your t-stat for the motor. The one with the bleed valve looks to be a hydrolic clutch in. The one with the shift pattern is trans inspection?


Looks like a pretty stock gixxer but that's just a guess.

If you need a shop TFOG is the one I'd recommend also.

Sounds like the jets are plugged up a little.

Remove and clean. Re-install and ride it to the srip club.....

Could be a number of things, pretty much all simple to straighten out. If the bike sat idle for several months, then the most likely answer is that the pilot jets in the carbs are clogged, and someone cranked the idle speed way up to keep the bike from stalling when the throttle is closed. Another possibility is that the choke bar was assembled incorrectly and is hanging one or more of the choke plungers open. A vacuum leak of that magnitude would normally cause surging, and the bike would not ride at all well. Gimme a call @ 303-216-2400 after 9 and I can probably narrow it down some more. [Beer]

1) sell your tools if you are not mechanically inclined
2) call tfogger, already mentioned
3) as tfogger mentioned if it sat more than likey gummed up carbs.

My suggestion is to fork out some cash for a tune up including having the carbs sync'd.

4) ride to your hearts content

Try that and let us know if it works. I gave that a shot, but it doesn't seem to do much.

+1 for clogged pilot jets. The guy I bought it from left it sitting in his garage for for 3 dang years!

I checked what I think was the choke plunger.

It looks to be clearing correctly, if that really is the plunger.

Anyway, I'm gonna take a few days to tinker with it get it registered etc. etc. And if I'm not able to do anything with it you're the first person I'm going to call. I've been asking around for a reputable motorcycle mechanic for a few days now and everyone here is singing your praises, that's good enough for me!
