Re: Does anyone know?
like the wiki says bout kinetic cranks...
_The newer Kinetic TFR-USA model engine crank/output shaft is cut differently than vespa and older Kinetic TFR models, so Vespa and older Kinetic variators and clutches do not fit. This can be remedied by swapping to a Vespa performance, or even an older model crankshaft. _
but really, if I was gonna get an expensive new case and kit, there's no way i would skimp out and run a 30 year old crank.
