fouling plugs..... James&Clark

2 posts in this topic


you guys have to be getting sick of me by now......

I have to really lean the jetting to keep my bike running...

to the point were I can smell the heat off the engine...

but when it does foul if I change the plug it will run great for a while, then foul again....

I YZ timed my bike air box lid off, baffle out.. now I was going to try DVP4# 178 main 48 pilot 1.25 turns out.. acc pump is about 1/4 throttle starting to squirt...

when I run it lean my pipe glows about 4 inches from the head this makes me nervous...
