I have a bmp fix kit with steel spacer for axys and also a wiseco fix kit with a aluminum spacer that's going into 09 dragon but have been doing some measuring and the steel spacer is close to .250" but the aluminum spacer is .263 and with both spacers you add second shim so my thoughts would be that shouldn't the spacers be less than .250 with second gasket to bring head to piston squish close to spec not bigger both pistons measure .250 more height from pin thanks
