HotCams & Porting?? Need Jetting changes?

Recommended Posts

Got bike back together started it and runs good but havent had a chance to go to the track. Checked spark plug and arm was a little whitish. Do you think jetting changes need to be made?

Not necessarily, ride the bike for a length of time and then evaluate how the carburetion performs.

I didn't need to change my jetting when I went to the hotcams on a Z400 but porting changes the ballgame entirely. It could come out a lot of different wats depending on the porter and what they did. If your plug us white yes, you need to start stepping the jetting up.
