Need new pipe-want more RPM
meangreen500:
I have a pc works pipe, and both my friends have fmf desert pipes they dont have the upper end rpm I got but i still have the low grunt too its kind of the best of both. just my opnion

It would also be worth considering getting a bigger carb if you want more rpm.
I think stewart and a few others are running a sudco 41mm, which sounds like the goods.
I have a fmf gnarly desert on mine, but one of the biggest differences i noticed up top was when i played around with a lectron 44mm carb on the bike.
It screamed and had a top end surge like a 250. But then a piston pin spring clip broke in half and destroyed my top end and i havent had the time to put the lectron back on yet since the rebuild :oops:

How was the low and mid with the lectron setup?
Johnniespeed:
When I had the brand new original stock pipe on, I had upper RPM power, then when I switched to the Gnarly Woods pipe the bottom end power went up, but lost RPM. In other words the pipe moved the power to a lower RPM. I was hoping someone has tried both the Gnarly Woods pipe and the Gnarly Desert pipe, and could comment on the difference. I have already ordered the Gnarly Desert pipe and will post my seat of the pants "butt dyno" results here in a few weeks. I am guessing the Desert pipe is designed for higher RPM and the Woods pipe is designed for lower RPM.
As far as installing a Lectron and destroying the upper end, I will leave those modifications for someone else who is more skilled than I am.

junk man:
So why not put the stock pipe back on ?
