WR 426 ENGINE OR YZ 450 ENGINE CARB MOTOR

[Kevmister]

I am looking for a WR 426 or a YZ 450 carburetor engine, I was riding my bike the other day and it seems like the conrod came loose from the crank and the bottom end of the main bearing went through the block. I need help with either replacing the engine or rebuilding the one i have. If any one has knowledge of where i can get a owners Manuel for this bike i will be great full.

Thanks
