What reed setup should i use? What about gearing? Its stock bore with mild porting, fmf sst pipe, and a k+n filter. Whats it gonna take to match the 450's on the track? Also what do you guys think of running elka shocks on lonestar a arms?

I ran the same engine setup for awhile with the Rad valve.13/38 gearing got alot of wheelspin out the gate so the 14/38 would probaly be better.On the track,I could run with any 450.
My setup was
Stock cylinder .050 over
low end port work
rad valve
Sparks MX pipe
38 A/S carb
215 psi compression

Just an opinion,if you ride a track that is composed of sandy,fine dirt,you might look into a dual stage foam filter.Mine had a K&N but I kept seeing dirt in the airboot.Switched to Uni filterand it hasnt been a problem since.The performance wasnt affected at all.
