Last time at the track, bike ran well. I red-lit first round so loaded it on the trailer and drove it home. It sat for two weeks. Went to get it out yesterday, kicked my guts out trying to get it started. Found I was getting no spark and eventually tore it down far enough to find my crank split in two at the main pin. Never showed signs before or while trying to kick it of being locked up.
Anyone ever hear of anything this before? This is about a 10 year old Port Magic 7 mill crank. Never had an issue before. Also, anyone have a ballpark of what it would cost to have it pressed, reparied, trued and welded to get back on the track? I haven't had a chance to call Rudy yet to ask him, but I think he farmed his cranks out to Louie at Twister anyway. I could be wrong.
The center pin looks like it just sheared. Not a clean brake, but not quite a twist either. More of a fragmented break.
