Proper Break-in Procedure

[muscle]

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 start mine up on the stand and warm it up for about 5 minutes using very little throttle, shut it down and let it cool. Then I start it up and ride it easy for about 10 minutes, stop and make sure everything is torqued down right and I'm ready to roll.

how does hte cold weather affect the break in? up here its usually below freezing so should i wait until summer to do the 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.
