CRF450R throttle cuts after main jet

Recommended Posts

Went from 168 to a 162 as the guy recommended from the shop. I live at 10,000 feet and ride higher than that often.

i can't tell if its a rich issue or a lean issue. it cuts out if i open the throttle quick and is smoking out of the exhaust split where the clamp is. its chilly today but don't think i should be seeing that smoke. (not riding just on the stand)
