Cant find the link on running in a motor but if you are using old pistons, a few squirts on the accelerator with a back of is all that is required.
Have you ever see race cars do 10000 miles as slow speed to run them in ?
New pistons, new hone, 2 - 3 heat cycles and pedal to the floor.
Quite and old video of mine.

Thanks Wallace,
Yeah, I meant the same rings to go back to the same cylinders.
What do you use for honing? Just a honing tool in a drill or you take it to a machine shop?
12500 rpm is not bad for a 4T single

. What can the CB125 twin do, if the singe can be spinning like this?
