So if mine has slipped (the bike still runs great right now) what is the solution? Does anyone offer a crank that is welded, keyed, splined or something to prevent the flywheels from slipping? If I keep this bike and rebuild the engine (if mine has slipped) I would not want to replace with a new crank with the same potential problem.

While we build/balance, and re-build/balance pre-1999 bolt-togather cranks here, and have for decades, using S&S Master Crankshaft Tooling,(just did a little 45" Flathead crank yesterday, for a client from Maryland) we release the press-togather crank assembly work to Hoban Bros./Darkhorse Crankworks, Newton Wisconsin.
Once they are completed with the needs of any given crankshaft, any pre-existing issues with that, will be put in the rear-view mirror.
