I recently bought a Wiseco crank off of eBay for under $200. I thought I got a good deal, but then my mechanic tells me that they are junk. Should I just buy an OEM or hot Rod crank now and just get it over with. Or would I be fine running the Wiseco crank with the timing retarded 4°. Do any of you guys have any experience with the Wiseco crank in your two strokes?
