Just for reference, what is the safe operating range for a stock 50cc 2t engine.

On my Stella I know it is high at 350, and hitting 370 is the seize zone.

What's it for the RH50?

Thanks -

It's all the same for essentially all air-cooled engines. 390ish is redline

^^^ Agreed, except for Stellas. I have seen them seize in the 370's. I tell my customers 350 for a little margin of error.
