    Ryan in WI

    Got it the first try

    Very easy all in one kit. Follow the directions and do it once. Jets are listed according to elevation and are dead on.

  • FMF Gold Series Pipe, "Fatty Moto"

    FMF Gold Series Pipe, "Fatty Moto"

    robert in NC

    Over all great fit on one bike and not so good on a...

    It's fmf so it's a great product! It does get much hotter than stock and the fmf factory fatty..not sure why although it does not not have as "twisted" and as large of an exhaust chamber as the pro-circuit and fmf factory fatty.. it some how performs just as well. Could be why it gets hotter..?.. the fitment is great on my 98 yz125 although on my 99yz125 (different part #, difference is the way it connect to cylinder) the kicker hit the pipe..that is 1 negative ..although not worth sending back. Also I wish I knew how to keep the fmf gold fatty series to keep from dulling.. maybe it's in the instructions..?.. It definitely increases hp. I would go with the fmf factory fatty if available for your bike..
