I am thinking about buying a Malossi MHR 70s kit, i was wondering how much power this would add to the engine, and apart from upjetting the carb what else would i need to do to ensure it runs properly?
Being a mid race kit it needs quite a few parts to get it working to it's full potential. A good high rev loving exhaust, larger carb, transmission upgrades, unlimited cdi, etc. You can just about get away with one on the stock crank but it's not recommended.
