timing engine cams valve

  1. 2005 Trx450r rebuild advice?

    My crank bearings went, motor locked. Now I’m opening it up and kinda need some advice as to what put into it. Should I get a hotrods stroker? Should I stay with the oem crank? Bigger cylinder and piston? Stage 2 cams? Anything is appreciated, I just want to make power and reliability.
