In regards to my brand new WB pipe. Ever since I put my new 130 main jet in, the end of my pipe has been collecting black soot. Any ways to fix it? What should I do or is this normal?

300EX I'm guessing? I found that when I had my 250X(full pipe, open air box, K&N) that it ran the best with the stock jet in it.

 

Yah, 300. My bad. I've been tunning it with a closed air box. Should I try an open box? Also, doesn't the black soot signal richness? Or am I off. It seems to run fine. Great actually. Just a little worried about soot.

 

It lets it breathe much better. Probably don't need to worry about the soot.

 

i just pulled my plug and it is black as night around the end by the threads. the weird thing is that the very tip of the bent piece that sits above the electrode is grey/brown. Rich I am guessing. Anyway to lean it out?

Hey, hylton400ex, what is a 929RR??

 

I believe a 929RR is a crotch rocket.
