Alright everyone, here is what I am running. 1999 400ex, ross 416 piston, S2 hotcam, K&N jet kit, open air box w/no toil filter, & 14t frt sproket. exhaust is stock except for ground out header welds. I know I should put at least a slip-on on it, but I dont want the noise.
165 main jet, 42 pilot, 3 1/2 on air screw, k&n needle middle position.
Any way checked the plug last weekend and it is black, not terrible but I am definitly running rich.
The bike runs great
What are you thoughts on my jetting to get rid of the black plug?
Colby mentioned to me that with out a pipe I might have some jetting probs.
What does ya think
All opinions appreciated
