As some of you guys know i am re doing my 96 xr650l and i was thinking about changing out the stock exaust with a stainless steel exaust. the question that i have is if i swap out the exaust will i have to re jet the carb. the bike sounds and runs great right now. the guy that jetted it before i bought it did a perfect job. wat to do. i thought about wrapping it with heat tape but that breaks down with time. any thoughts.
