I am going to replace my old piston (95 hours) by a Vertex cast piston.
In order to break up this piston I am thinking to do 3 heat cycles.
1) On the stand 5 minutes from idle to 1/4 then let it cool down
2) Another on the stand 5 minutes from idle to 1/2 throttle and let the engine cool down again
3) Riding around with a small load at 3 and 4 gear slowly for 10 minutes and then riding normally but without let the engine cool down.
Is it acceptable this procedure for a cast piston ?
Thanks.
