I went 100+ on the first piston but it was too far.I won't do that again.In fact the engine is getting a total rebuild this winter.

yep,that's too much
I do about 30hours in supermoto ,I realy wrench the bikes neck so I don't want to risk anything ,also put a new camchain when changing the piston ands check the valves every 10 hours
