Max RPMs on a 225 ProMax???

Whats the max RPM on a 225 ProMax??? PreMix fuel and Top pinned pistons??

I turned over 7000 on my 200 super mag. It's the oil gear that won't handle the rpm.

If the pistons are top pinned then the next real weak link of the chain if the oiler gear has been removed is the fragile cast pistons ... I cryo treat most Pro max cast pistons to make them more durable if the customers wants to turn more and do not want the forged piston issues on steel sleeved engines....
