I have a 1987 yamaha warrior i have a stroker crank for my quad but i need to kno what is soo special about a stroker piston cause i cant find one that is bigger than 84 over i need one bigger and i want to kno what makes them soo special

 

I don't really understand your question. A stroker piston has a different pin height to make up for the longer stroke.

 

i think he's wanting to go bigger than 84 mm, you should be able to find them.
