Cases can be cleaned up. The dealer or machine shop can clean up the crank shaft and install the rod. Just call around for prices OR you can send it to Ritter Cycle Racing - FAST, NOT FICTION. or numerous online sites if you don't have anyone local.I have had cranks rusted solid,cases in just as bad condition,but was able to get em running.If you don't have a manual get one! Doesn't matter what year model on the 250 manual as the internal mechanics are the same. OPT

my mechanic is putting in the rod and crap for me. i dont have time but he has no job right now so were helpin eachother out, but i need to send the crank and the crank case to a machine shop and they will know what needs to be done?? do i just tell them to clean it?? or what??

If rod has ANY up and down play on the crank(side to side is ok) the engine wont last with just a top end! Also make sure you roll the rod around and if any bearings feel rough they need to be replaced. Just trying to save you some $$ if the rod or crank bearings go out. They can take a new top end out with it! OPT
