What the recommended steps for a break- in after a top end rebuild ? Oil, valves, etc
Replaced heads with new valves, springs, valve guides; new 96 mm pistons, and cylinders. 500 miles ? |

Probably most important for a top end rebuild would be to seat the new rings. Take it up to redline under load and then decelerate to idle. Do this 4-5 times and your rings will be seated. Change the oil... Drive as normal.
