I dont even know really what the thing does but how much of a difference will it make to a stock 50? Well I have -1 in the front and stock rear sprocket..Other then that my bike is bone stock.

 

I don't know how much of a difference it makes but what it does is it raises the rev limiter.

 

thats a sick avatar BTW.

 

Its not gonna do much to a bone stock motor, but when you add parts like intake and carb, air cleaner, exhuast, 88cc kits it lets the motor rev out higher.

 

^^ Now thats an honest man with with one hell of a product line. Now very many sellers will you find to be that honest when it comes to their product. MOst of then just want to sell their product. But Ryan on the other hand, also wants you to know what to expect from the product........So with that being said. Ryan knows i'm a 50stunt customer for life, hehe....=-)
