    Scored a sxr... Needs some engine advice, 750 engine the same?

    So I just scored a 2007 sxr 800 with a completely blown engine. The crank is completely seized, rod broken and blew through the case and busted the starter too. Head is good, cylinder sleeve is busted off on one of them so I have a couple questions. Basically I'm looking for the least expensive way to get it going good again.
    1. Are all 750 big pin crankshafts and cases the same as the sxr 800?
    2. Can I order sleeves for the cylinders then get a local shop to do them? Most machine shops/engine rebuild shops should be able to?

    Basically what I'm thinking is to get a bottom end from a 750 big pin, then resleeve the cylinders that I already have and obviously new pistons and gaskets etc...... Am I on the right track?
    Also if anyone has a link for a sxr 800 manual I'd appreciate it.

    Thanks in advance

    All big pin cranks same. Don't waste time on sleeves buy a cylinder. Sxr cylinders are hard to come by. Xi is similar. Sxi is best speed. Sx is fine. All can be bored to 82mm to start if you have sxr Pistons

    Thanks, so in the hr since I posted this I bought a small pin 750
    The head I have from the sxr has dual cooling so I want to put that on, anyone see any problems there?
    Also any issues with electronics? Just use all sxr electrical?
    Cheers

    Anyone see any issues with putting a sxr 800 cylinder head on a 750 small pin engine?
    I plan to put the sxr stator and flywheel on the 750 small pin engine, all other electrical is stock sxr.
    Is that all good?

    You'll need to use the small pin flywheel, the SXR flywheel won't fit on the small pin crank.
    Never argue with an idiot, they will drag you down to their level then beat you with experience.

    Kevin Redinger out of WA sells complete motors (with ign and ex) for around $1300-1500 US.
