Help! I need a crank for an 02 wr!

Recommended Posts

I recently posted about stroked and bored wr250f's, i found the big bore kit, but im having all kinds of trouble finding a stroker crank for an 01-02.. does anyone know where i could find one?? Or even a standard aftermarket one? I've found the oem crank but from what I've read they had problems with the diameter on the connecting rod wearing and causing issues, the stock rod in mine had this issue as well, it was about .001 oversized.. anyone know what the problem was? I assume that aside from the pin being smaller than the 03-current that the rod was not hardened as much as it should have been? Thanks in advance!
