Re: 200w petrol motor
I live in the ACT. Local law says 200watts here. However, if you can prove that your bike can only produce 200watts via a certification engineer or dyno run like they do with the rock solid kit, you will be ok. Then get an engine plate made up saying 200watts with the manufacturer name on it.
You could either limit the amount of air going into the engine with a smaller intake gasket or re-jetting the carb during testing.
