FMF Pipes
RICHK:
Can anyone outthere explain the apperance and powerband differences between the Gnarly (woods) 020055 and the Gnarly (desert) 020038
the fmf web site has the same picture and discription for both pipes I know the woods is low end and the desert is mid high but if i go with the woods will i miss the top end is it less than the stock pipe top end i plan on running a reed spacer on a completely fresh motor with the KIPS mod a Rad valve and might even window the piston i am your typical picky whiny consumer i want everything and don't want to loss anything anywhere this poor bike has to do everything with me tight mountain trails, open logging roads, sand dunes, riding with the wife and kid and even the local mx track when i feel crazy . any help, stories or helpfull wisdom would be awesome and pictures so i can tell them apart online
thanks
Motorrad:
the woods signs off EARLY.. You WILL give up top end..
Id also not reccomend the reed spacer... you will give up...
look at V-force reeds...

Sounds to me like you should be building a nice kx285 or 310 to do everything you want to do with the bike. Yea I have K5's but my everyday rider is a K2.5 that I also have a 310 cylinder that I swap on and off, depending on the riding- it loves fuel and I have to carry extra .CBX

I tried both FMF series on mine, they worked pretty good. That Gnarly really does sign off quick.........brutal off idle /low end torque though. I ended up with a PC Works. Powerband seems to be like exactly what your looking for. I use my bike for everything from lugging on tight trails to MX racing, works great for anything you can throw at it. If you have to run an FMF I'd definitely go with the Desert version, very good pipes.
I run the V-Force 2 reedcage, with reeds set at high tension setting, 10mm reed spacer, thin metal head gasket, KIPS mod, ignition set on full advance mark,VP C12 fuel, Mobil1 2T syn at 80:1 and Iridium plug 1 notch cooler than OEM.
I'm curious to hear others chime in with which set-up is best on their bike.

is the desert the pipe with the kink around the rad cowl like the oem did or the low boy looking pipe
