Plug Question

[Bender]

At the tip of my plug there was a hard white piece of somethin stuck to it. What is it and what causes it?

spark plug? If it is your spark plug than you may be running REALLY lean. Got a pic?

[Bender]

No i dont have a pic but i know it was running lean cause i ran straight pipe all the way back and had the air box lid off and never rejeted. I noticed it when i pulled it out to rebuild the top end but after the rebuild i only whent to a 118 main jet. Is that big enough? What about the slow jet and needle clip position?

[Tri-ZNate]

what is the stock main jet?

[Bender]

I think it is a 108 but im not sure.

[Tri-ZNate]

if its a 108 stock you should be good if your running a straight pipe and lid off. But do a plug chop with a new plug to make sure.
