1. .40 Bore Out How Much Speed/Power and what atvs can i keep up with? 2. What FMF REEDS Power Lite Carbon Fiber Reeds or Dual Action Torque Reeds? 3. What Good Does a FMF RAM VALVE ? 4. What Size Piston Goes With a .40 Bore Out?

 

I have heard very good things about the boyeseen reeds. Aslo I wouldnt waste your money on the ram valve. They make less differance than the reeds do.

 

my blaster is bored 40 over. all it does is bump it up to an even 200cc. it adds little, if any, power. the best reeds I think are Aktive Carbon Fiber. Ram valves or Rad valves do nothing but lighten your wallet. a .040 bore takes a .040 over piston. when you order a top end rebuild kit, get one for .040.
