RE: FC 450
WXC
I have a couple friends who use the FC 450 in the trees, and ours are almost if not as tight as eastern stuff, but with more elevation changes. Motor works excellent, and ride it to see if the trans is too tall in 1st or short in 4th, both of my friends bikes have had the xtra gears put in. A progressive spring in the rear makes it magic. That leaves the front to fiddle with.
The ultimate woods machine in my opinion is an FC 450 with the 380 kit installed w/6sp. Use the cam from an 00 400 EXC and you will kill anything in the trees. I used this set up on my last fe 380, and it carried my 240 lb carcass around at 'A' speed, with a big smile on my face.
Enjoy the FC.
