Be sure to replace your Rod with an aftermarket one. I am a believer now that mine went with hardly any hours on my 690 kit.

 

get a 12 or 14 tooth sprocket

 

a 12 tooth sprocket will help with low end acceleration, but be prepared to lose time in a 300' drag. A good set of sand tires are reccommended if you plan in riding in the sand. A set of turf tamers or holeshot like tires would be fun in the trails, (they would allow you to slide the rear end out more.) I put on a durablue +4 axle and +2+1 a arms. Also nerfs, handlebars, and I have purchased an 11:1 wiseco piston and a stage 1 webcam to tide me over until Sparks gets around to getting my 690 kit in.
