I have a question for you Yamaha gurus. I'm rebuilding this 98 yz250 and its a basket case. The top end was ran way lean and melted down. The crankshaft seems ok to me but the threads for the flywheel are destroyed. I've found some wiseco kits on eBay that include a whole crank with rod and all bearings, a piston and whole gasket kit. The problem is I haven't found one for a 98. From what I have found in research it seems that a crank from a 97-02 is all the same. Is that correct? I'll include a pic of the kit I'm looking at. Any advice is appreciated.
