Proper Break-in Procedure

Well I just did my best top end rebuild ever. It went so good I hesitated putting it back together and covering up my work! :yeehaw:

My sons 98 RM125 has had a lot of use and probably 20 top-end rebuilds. The cylinder measured at spec but needed honing which I completed no sweat with a nice 45 degree cross hatch. (it was purdy)

Anyway one thing that was nice about this rebuild was my new parts washer. Man this made a differance!

My quesdtion is : what is the best break-in procedure to use on a new two stroke top end?

I dont think the cold temp will affect the break-in but probably jetting will need to be adjusted. Plus in the winter is when I usually devote more time to rebuilding rather than during the summer and peak riding season.

Anyways the RM sure is purring. The boy willenjoy the new felt power too. Were going riding today. Should get to about 64 degrees here in Eastern AZ.

:yeehaw: ;) :yeehaw:
