more jetting

2 posts in this topic

I need more help with jetting my 99 400. I am now at 175 main and 50 pilot. I noticed last night that my pipe was heating up at idle. Does this mean I should go even larger on the pilot? I also purchased a White Brothers E-Series pipe and silencer.

Does anyone else have one? If so how many discs are you running?

Thanks

Nick

I think all 4-strokes pipes glow in the dark, so don't jump to conclusions and assume you are jetted lean.

My 426 header glows after about a minute. After two minutes its almost translucent. Of course this is only apparent after dark, in broad daylight the pipe looks normal.

Pilot jet should not effect mixture at idle. Idle mixture is altered by adjusting fuel screw at bottom of carb.
