I race the +40 class in local motocross and quite often have killed the motor going into tight turns. Do you think a flywheel weight would reduce the chance of killing the motor. My thought is more intertia to keep the motor cranking even under heavy braking.

I added a 10 oz. Steahly flywheel weight to my 426 with great results. The engine accelerates the same as before only now I can enter turns without the fear of stalling.

Does the engine stall or are you killing the engine? If you stab that rear brake when coming into a corner that along with the compression braking you'll lock up the rear wheel you'll kill the engine and with all the compression unlike a 2 smoke it wont relight itself.
