    750 SX/800 SXR engine part selective inter change question

    Is it possible to switch certain engine parts out on a 750 SX engine with certain 800 SXR parts? Being really new to the PWC community i am unsure about inter changing parts and the compatibilty. I have been looking around and havent really found a solid answer to my question. Who would be the resident expert in this subject and can somebody point in the right direction. Looking into it I am thinking it may be possible to change out the cylinder and head on the 750 engine and possibly swap them out with the 800 SXR jug and head. I may be going in the wrong direction with this and if so somebody stop me. If this does actually indead will work, how does this/what impact does it have to the engine dynamics?

    To tell if a 750 is big pin or small pin you look at the color of the engine block. Silver is small pin and green is big pin.

    Not Really!!! but green usually meens BP (unless it was rattlecanned) The 95 Sxi is silver and also a big pin w/12 intake mani bolts.. 95 was the phase out/in period for 20/22mm wrist pin size. Porting was changed along with ignition timing for 95' & up to 2003etc etc.. 10 bolts on the intake side of the cases mean small pin & 12 usually mean big pin. I say usually because some of the 92-94 sit downs were small pin dual carbs and had either 10 or 12 bolt manifold intakes. There is a supplement to the manual for 95' years only.. I need to find one myself, I have gathered alot of info but still want/need more.. If anyone has a 95 750Sxi manual supp on pdf. please get ahold of me. Always trying to learn more. Thanks, J.

    Edit to add: forgot to answer OP's question.. Yep, Big pin case, sxr cylinder & head & research..
