fitz did you get the link I posted? its a good faq on jetting.your clip on the needle is 2nd from the top? and is it a stock needle? if so move that to the pointy end 1 position and try that. the needle controls 1/4 to3/4 throttle so if thats where the problem is thats what you want to work on. dont chage to much, I'd change one thing at a time. the main jet controls wide open throttle. where exactly does your bike bog at?
ill pm you the link also...
