I have two 50cc bikes, a Honda CRF-50 and a Yamaha TTR-50E.
One would think these would be simple to keep running... I was having issues with the TTR-50 racing at idle. So I tore the carb down, gave it couple good ultrasonic baths, shot all the various ports with carb cleaner, replaced the idle/pilot jet, replaced all the gaskets, replaced the air filter, and put it all back together. It is still getting too much gas. When I try to start it, I can smell it even with no choke on. I pulled the plug and it was wet. I dried it and put it back in. I turned the fuel screw all the way in (this is the screw used to set the idle). The bike started and I turned the fuel screw back out 1-1/4 turns. The engine is still going way faster than idle and backing the screw completely out of the carb does not slow things down at all. I am pretty sure the throttle is totally closed and the slide bottomed out. All the jets are stock.
Any ideas?
