just got the yfz running. did a warming cycle on it. and burnt a half tank up running threw the gear from idle to half throttle. i started to go from idle to 3/4 for the rest of the tank and its sputtering and poping.

yfz ha an athena 490, cam mod, mild port work, kandn intake and baffle removed in the stock pipe for now so the neighbor doesnt complain. i forget what my jetting is at the moment but when i look at my jets in the shop tomarrow i will beable to let you know.
