CRANKSHAFT Rebuild

My crankshaft let go in my crf250x. Turns out the trush washer broke and came off the pin and started trashing around, the bearings are still intact barely. Honda's warehouse has complete cranks on back order and don't know when they will get them in. I have not found and after market 250X crank. Hotrods has a rebuild kit. I have built several 2stroke cranks but never a 4stroke, anything special I need to know about this task?

Motosport had a oem crankshaft on the shelf. Found it while looking for a rebuild kit. Should be here wednesday,all is good.
