I am still having problems with my bike. It is still idling uneven and puffing out small amounts of darker smoke.

I checked the spark plug and it was "carbon fouled" so I replaced it and that helped the idle (for a day), but now it is uneven again. I checked the spark plug chart and it says "carbon fouled" plugs are due to being too rich, so I was wondering how to resolve this problem.

Any help would be appreciated as it is too nice here Cali to NOT be riding! Sad

Reply #17 - 03/25/09 at 14:54:13 Is there a way to check the float without taking the carb off AGAIN? I took it off the other day and it still looked very clean from the time I cleaned it.

Reply #20 - 03/25/09 at 18:08:24 Does your carb have a drain teet? put a clear line on and hold it up next to the carb. open the drain on the bowl. and set the petcock to prime. gas should come up in the line even with the bowl gasket.

You got a leaky float or your float has sunk or is stuck. does the fuel shut off? Then it floats. Is the fuel level low? readjust the the tab for the shut-off.

Reply #23 - 03/26/09 at 21:07:36 Rion, Here is a good test of your petcock: Crimp the petcock line completely shut. I mean completely. Run the bike with the petcock set on PRI. If your problem clears up, then that points to a bad petcock diaphragm. Good luck!

Reply #24 - 03/27/09 at 15:46:45 Well I have tried the Petcock idea and there was no improvement. I also put a clear tube on the drain hole and the fuel level comes even with the top of the float bowl. Not sure what else to do, Please if anyone can help, I need it!!! It's GORGEOUS outside!!!!!

Let's see:
Running rich with hesitation during acceleration
Petcock- good
Floats- good
Air- good
Spark- good

I'm assuming nothing clogged up the tail pipe. So that just leaves dirty carb (again) and something seriously wrong with the engine. Hmmm... so why did you have to clean the carb 2 months ago?

My money is on a carb problem. likely a dirty pilot air jet. Other possibilities are worn main jet,/needle or slide vacuum hole plugged (rare) not functioning properly creating excess vacuum and pulling the slide up too early.

I don't think you've mentioned any carbs mods done. Have you done any?

Reply #26 - 03/27/09 at 18:30:31 I don't know but it appears that the white spacer is thinner than stock. spark plugs are carbon fouled I cleaned the carb last time due to running out of gas and not being able to start it afterwards. I checked the carb a few days ago and it looks very clean

Sticking slide.

Sounds similar to oldfeller's description:
"I have mentioned some "wonky" running characteristics from getting Mazola oil transferred from your oil laden dust trapping air cleaner to your constant velocity vacuum actuated carburetor slide.

When this happens you get slower response to throttle off changes and generally rich running condition as your slide movement is always responding slowly and is always behind the power curve so to speak."

My experience comes from good ol' natural creationist dirt. His dirt is artificial, un-natural, darwin type dirt. I wouldn't trust it.
