Just bought this 02 gp1200r from a friend motor is locked up. Pulled head today piston in rear is burnt, cylinder is marked up in 3 places then I found oil line was off carburator. Has anyone had this kinda trouble? What about going to premix? Am i looking at a topend or will crank bearing need replaceing to? Thanks for any advice this is my first ski.

Very common for the oil injector system to fail at some point on that ski. That is why so many go premix. As far as need for just piston/cylinder or more is hard to say until you tear it apart some more.
