Na, even old fmf's hit. I'm not trying to determine what fits I,m trying to find a "proper" pipe, "it rips" dosn't tell me anything, have you dynoed it?
besides a rz motor is way different, sure there both 350cc's but there is nearly a 20 hp differance, a two stroke is way different than a 4 stroke because of the expansion chamber, if you cut out 2 inches out of it what happens?, how about 2 & 1/8? or what about 1 7/8? why 2"?. I guess what I'm trying to determine is chamber volume and try to match it I only whant to do it once and properly!
I don't whant to settle for close or good enough.
