what is the float settings for them? this could be my problem for my stumbling....couldn't it? i know you guys know.

 

float level should be 0.52" (about a 1/2 inch)with the carb upside down measure from the lip of the carb lift the float till it touches the needle (but not compressing it) and measure to the top of the float. I use the small ruler that came with my feeler guages (about 2" long). if your floats are off you can expect problems when you wheelie, climb steep hills, and sometimes on hard corners, usually you can smell the fuel from the overflows

 

thanks alot v.

 

RRR, are youi STILL having probs??

Go get a float tool from Yamaha, You attach it to the drain & don't have to remove the carbs to use it. It's just a rubber hose with a clear calibrated plastic tube on it, so it shouldn't be too expensive.
