[QUOTE="rairden, post: 678214, member: 42933"] I don't know the answer to your question. I'm sure that it's safe to say that the manual did take it into account though. sjmaster, as you may have read before(in the 3 YZ250 threads about jetting) I'm going through the same thing you are. Do you bend the float tab down (if you were looking at the carb upside down) in order to raise the float height. So your float height is now at about 9.5mm. Mine is at a low 4.5mm(thats how its always been). Have you tried measuring it like keihin.com says to? So what's the floats purpose? The petcock is turned on and gas flows down into bowl of the carb. That causes the float rise w/ the gas and "float" ? What the hell does that do. [/QUOTE]
