I am having problems with my 05 ttr250, I put an exhuast on it to release some power but have released some other stuff too.. after running for just a few minutes the exhuast started to glow, and my plug is burned black.. I know I should jet the bike after an exhuast, but does anyone know what I should jet it up to I am pretty new to jetting bikes so any help will be nice..

I would not have expected a four stroke to require jetting changes due to a change in the exhaust.

You didn't accidentially leave the choke on, did you?

Any other changes?
