when did you look at it -after riding full throttle and hitting the kill switch?-running at idle-cold - hot? clean air filter? temp outside ,any new mods
i started it backed it off the trailer and parked it. it was about 45 degrees
no new mods latley and the air filter is clean. it may have been black since i put in my new UNI filter
