    I am riding a 2008 kfx450r that I purchased a while back. Just recently my slip-on cracked and it's totally falling apart. I believe it is a Two Brothers M7 full system. I'm having troubles finding somewhere to buy just the slip-on. Does anyone know where I might be able to get one??

    I currently have the big 3 and stock sprocket set up. I have a 15T front, but it's not on yet. I am considering putting in both intake/exhuast stage 2 hot cams. What will this do for performance and for longevity of the engine?

    I bought my 2008 KFX450 in excellent condition, low miles, and bone stock. I added an HMF slip on pipe, K&N intake, and an HMF optimzer. It sounds pretty good and in my opinion runs pretty good. I am pretty new to the sport and don't have much to compare it to. Apples to oranges, but I get...

    Unfortunately this past weekend while riding in West Virginia, I had a bad encounter with a steep hill and a gas pipeline. The quad ended up rolling down the hill about 30 feet and smashed into the pipe. All in all it managed to break everything on the right side, but the plastic. (as you can...

    OK, here's the challenge. I've had my KFX for a year now. I've been to the Florence, OR dunes, the Moses Lake, WA dunes, and rode probably 100 miles of WA trails so far.

    First off, I'm new to the forum.. I bought a 08 a few weeks ago and I've been thinking about retrofitting an extra stock kx250f muffler onto it until I buy a nice system. It wouldn't be for performance, mainly just aesthetics. I have seen the same muffler put onto a trx before.. If anyone has...
