With everything correct there will still be a break in period to seat the rings. Don't use synthetic oil. Do run the engine for a few 6 or more heat cycles lightly throttling before riding on the road. A few short break in rides with on and off the throttle riding will help seat rings. Depending on how tight you set the motor up will dictate how many break in rides you take. An engine with only .001" piston to wall clearance takes longer to break in than one with 1.5 or 2 thousandths with same piston. Clearance is set depending on manufacturer's recommendations based on piston alloy, forged or cast and intended use. 20,000 mile street use or one night at the track...make sure your cross hatch finish on bore face is correct or rings won't seat. Just couple ideas. Erik K
