Default crankshaft balance factor

In article ,
says...

A parallel twin cannot be fully balanced because there
is no way that a single rotating mass can fully cancel the pure
up and down mass of the two pistons.


Best bet then is to cut off the two cylinders and weld them on the
sides of the motor. This makes an engine with perfect primary balance.

:^)

Actually the best bet is to contact a bike salvage yard and
get the part that's busted.....

Cheapest and simplest in the long run. Anything else is going
to result in an investement in time and money that *won't* get
paid back. If Kaw could have built 'em that way, they would
have.
