crankshaft question (really wierd)

[sambo]

I pulled the crank today and it was definately twisted!

Yep! I did the same thing on my GS1000 when I was 19, I was racing a Honda NSX (car) and my motor went BANG!!!
I rebuilt the engine, 4 pistons and 4 valves.... cost me a small fortune and it would not run right.....
Stripped it completely down and the crank was twisted!!!!
Don't fool with that crank, GET ANOTHER ONE......

Do I have to get another 78 crank or would another year fit. I'm just wondering because I've heard 78s were the only ones that had a real problem with this, and I would hate to have to do this again. Although, I'm getting pretty good at tearing my engine down.

I'm not sure, Post the question, I'm sure someone will know, maybe Keith Krause.....

Give John Pierson a call. He is THE crank guy I use. He is in Dayton Ohio. He can help. He has done every GS crank I have had built and never a problem. He is very reasonable also.
