any polaris 800 rebuilders out there i have a razer with a broken valve. it managed to go through the piston. so all i need to replace is a piston and valve. the biggest question i have is the valve seat got recked alittle and i was wondering if i could replace it or do i have to get a complete new head. also were is the best place to get new parts, ie piston valve gaskets ring seat, or new head. thanks for any input you give

 

Any good machine shop can replace it. I have done hundreds of seats in aluminum heads.
Sorry, can't help you with parts.
