<< I was impressed with the difference simply adding my FMF pipe made... Completely changed the attitude of the engine &amp; gives it that signature tinny race 2 stroke sound.

I guess I would say, the first time I rode it after putting the pipe on was more the &quot;Holy Shi+, I wasn't expecting that much of a change&quot; response. >>




Where did you get your fmf pipe? I am looking for one for my '82 250r atc [img]i/expressions/face-icon-small-smile.gif[/img]

Hy bro`s R is undergoing a complete rebuild. It should be ready in a few more weeks, with a 290 cc sleve. Can't imaging a 350 powervalve, that gonna be cool. As for the power of the moter stock was higher than any stock quad, due to the higher engine psi given by the head gasket. I do beleve that it was in the high 20's (27-29). Anyway to make a long story short I spent heaps on my 4 wheel R and could never catch his top gear?

 

If you get a new pipe, then be sure to get a new air filter (as well as rejet) to see the best gains.
