ok, so i have had 2 wiseco cranks in my warrior, first went in with a new .020 piston, just running stock valves an over sized cab and a slip on, it grenaded at about 40-50hrs sheared the crank between the main bearing and flywheel, no biggie, called wiseco rep and got a "thats odd, must have been a lemon, send it in we will inspect it and send you another." so i sent it in, 4 WEEKS later i get a call "yes the crank was a factory defect, a new one will be sent out monday" got it a week and a half later, put it in and didnt notice it bent a valve, so i did oversized valves, P&P and a hot cam stage 1. get it back together, no big deal, runs about 10-15 hrs and the cylinder is shot (didnt go together perfectly clean) so i bored it to .040, threw out the base gasket to bump compression to 11.02:1, ran it maybe 20hrs, and it blew the second crank! same spot same deal, i call the rep again "sorry but 40 hrs is a long time on a 'race motor' we wont even inspect it. have a good day." so i said "to hell with it!" and decided to build it with a rebuilt stocker! here is the pics of the damage to the motor the second time (sorry no pics from the first one) first tell the crank broke was how the flywheel collar was shoved out the side. it was burning clean so it didnt get hot and burn up. crank never even got hot!! it bent both valve BAD. you can clearly see where it sheared it off. i hope this will warn future buyers to NOT buy a Wiseco crank for ANYTHING.
