Hello, I plan to be buying a 53.50mm big bore and a cam from dr.atv for my 90, doing a valve job and porting the head. What carb should i use? I was thinking a crf 100 carb would work well with a 2into1 petcock. Also another question would be for exhaust, will a crf 70 exhaust work? I can bend if need be but is it close to fitting? I dont care for the dg exhaust and would like a cobra but cannot find one.
Congrats on your build! It would be best if you posted these same questions in the regular forum. It seems this group doesn't get a lot of traffic; or maybe it's my perception? There are some top notch performance minded folks out there; hopefully they will chime in.
