I run Klotz super techniplate. My reason? I love the way it smells. Yep. 32:1 smells great, runs good, ain't fried a piston yet!!
As far as the shocks go, I had my rear shock rebuilt at GnR motorsports in Walton Ky. They did a great job. If you haven't done muchsuspension work, (like me) then find a shop that sets up motocross bikes. Get somebody that knows what they are doing. My single rear shock parts and labor was somewhere around $200. but I really don't remember the exact amount. I do know it was worth it.
