I pulled out the motor last night. its locked up tight. so its 100% out of the ski. carbs are still on it and the exhaust manifold. I am going to try and pull it apart tonight and figure out exactly whats wrong but since I already have it out, what mods should I do?? go premix?? it already has a shredmaster ride plate, RD intake grate, worx sponsons. this ski is going to be used as a 3rd or 4th ski. not riddin a lot but I would like it to atleast keepup with my 03 riva stage 2 GPR1300 and light modded R12x.

thanks guys
