F/S is a cylinder head for an 800R motor. It has been milled by BJ (I don't know how much). It is in excellent shape and will fit 07-10 800R engines.

Looking for a set of high altitude domes for a BMP F7/M7/x-fire7 head. Would also consider another head with high and low altitude domes if the price is right. Please PM. Thanks
