The whole point is to keep the engine up in temp and then raise it and lower it within a range, so the piston forms to the sleeve.

the other thing is I replace the connecting rod after break in, in fact I use a "break in" rod then replace it. What a break in rod is one that I use to break in 3 motors then toss it. When I get a new motor, I take the new one out, put in the break in rod, break in the motor, then put in the new rod. Yes, this work, but what you do not want to do is stress the rod. The other way you do this is to heat up the motor before starting it when breaking it in. A lot of stress is placed on the rod and pin on the crank when the motor is new and cold. The other thing you need to remember you what less "pinch" in an on-road motor then an off-road motor. We are looking for higher RPM in on-road, and you are not on the low end of the motor as much as you are in off-road. Less pinch allows the motor to rev and the pipes and clutches are design for this operating range. Your clutch settings are VERY important, and if you know this sorry I'm not trying to insult you.
