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.

I would like to know if a crf450r crank and piston would fit in my 2005 Trx450r. I can’t find a trx450 crankshaft for sale but I found a crf450 one and wanted to know if it’ll fit inside the engine. Please get back to me. Thank you.
