im going to install a je 11:1 piston in my raptor and i just wanted to know if i should have some head work done on it.how much hp do you think it will gain. thank you

 

If your already going to have the engine apart and have some spare cash. I would look into it. I own a DS and I won't do any head work until I need a bore or valve job. But then I'll have it done right, by someone that knows the rotax engine like Team Pami or Woods. Now I don't know of any shops that you can call but I know there out their.

Good Luck

 

I would definately do the head work. This will give you the biggest gains along with the piston you are going to install. Quad central 2 will do it for $300
