Finally got around to working on the 750. Last time I rode it ,2 months ago, it seemed like it was only runinng on 3 cylinders. The time before that , two weeks, ran great. Found two things, glogged slow jet and stuck float needle. Bike runs good now, little lean, could use next size main( 122s, 4-1 , pods). But it seems like when shifting and sometimes when blipping the throttle that it hangs up or closes slowly. All four slides are smooth and work great, but I could see them start to snap closed like normal then close very slow for the last 1/8 of an inch while I was blipping the throttle. Is this just the slight lean condition? I never noticed it before but I have not done any real ridin on it, just trips around and up and down the block.
