my bike runs great on top and bottem end but if you push the throttle to suddenly it falls on its face. i tried droping the needle to the 5th notch but that did not work so now i am back at the 4th and it falls harder
These things depend on if you are running a pipe and your main jet size but I'd imagine around a 170-172 should work. Also might want to look at a 45 or 48 pilot. Hope this helps. :yfz You can also do a search for lots more info.
