wiseco crankshafts are junk went thur three thought the first one just a bad one that happens
sometimes but the last one diddn"t last a half hour put in a oem crank and bike is still running
but on the flip side their pistons are number one in my book
Rm125 Crankshaft works great I have been running the bike now for about 10 hours and no problem I put a new piston in as well and have no issues with it
