cleaned the throttle plate and float, still doing it, is the black plastic cylinder inside the carb the choke?

I'm not sure what part you are talking about,but it is not the choke.The choke (enricher) is the plunger on the end of the clutch cable that unscrews from the carb.If you download the manual,there is a exploded view of the carb with instructions for disassembly.This view is from BikeBandit,it may help.

Just to clarify, when you give the bike some gas (throttle up) the revs stay high before finally coming down to normal?

If so, that sounds more like an air leak than a sticking throttle. If you've taken stuff apart this many times to clean them, its more likely that we're just overlooking an air leak somewhere.

From personal experience, something as simple as 4 little holes in the back of your muffler (for noise purposes...don't do it) can cause the idle to "hang" before dropping back down to normal.
Also, there is an "S" tube that runs from the top of the crank case into the bottom of the air box. It acts as a breather tube for crankcases cases. I accidentally slashed a gash in mine one time with my shoe and it wouldn't let the bike idle right.

You need to pull off the gas tank and go over every single rubber hose to make sure that they are not gouged or cracked or not properly connected at the ends. I'm really starting to feel that it's an air leak. And to find it, you'll have to check more than just one hose. Worst case scenario, you buy 6 feet of rubber hose and replace the 2 or 3 hoses just to be sure.
Remember, this bike is 10 years old.

While you are digging around you should check the air box drain tubing. It should have a plug in the bottom end and is only unplugged to drain moisture out of the air box.

What about the black rubber diaphragm under the carb top...
If someone has tried to rejet the bike and that black diaphragm was not centered properly, it would cause an eternal air leak that no amount of adjusting the idle or cables would ever solve.

When removed the carb for cleaning, did you remove the black plastic top?

feltner58 · 04-11-2011, 04:18 PM

Yes I removed the black top

**jonathan180iq** · 04-12-2011, 06:09 PM

Did you verify that the rubber diaphragm was centered correctly and sealed? Even being a little bit off will mess everything up.

feltner58 · 04-12-2011, 07:58 PM

Ill check it again, Its frustrating because it runs really smoothly but its just at a high idle like it runs at enough rpm to take off in first, I can ride it but its just not right

**jonathan180iq** · 04-13-2011, 08:34 AM

And even if you crank the idle adjuster all the way and loosen then tension on the throttle cable it stays high, right? ....

This is one of those that would be a lot easier if we could see it in person.
