It looks like the problem is the inner webs have the crank pin cast into them, so the entire wheel would have to be remade to service the pin were it worn past spec. At least they last a little longer than the TZ units

Piston, rings and wrist pins are available aftermarket, and most of the gaskets and minor engine internals can be made or repaired if NOS isn't available. But the cranks.... they are vanishing and getting ever more expensive.

Not quite a TZ but I have a 91 TZR 250 3xv1 and have exactly the same problem with the crank, spare cranks are hard to come by! Japan has stock of complete new units, just have to figure out how to ride without an arm and a leg!
