Yesterday I got the silencer mount done. There is a comical amount of room for a two stroke exhaust on a four stroke. I actually had to space the mount out from the frame to center it in the space.
I also got the suspension in today. The front forks are the KX450F air forks with Dal Saggio Sphere inserts and coil springs. Brian at N2Dirt Suspension has had really good luck with them, and calls them the most plush stuff you can get. The second picture is after I got them.
