Let's say someone has a Tomos A3 that has been cut/welded into case induction. Let's also say that this same person is exploring their options when it comes to air-cooled cylinders that will work with a 43mm stroke and a 12mm wristpin.
According to the wiki (re: moped and scooter strokes)
43.0 mm = Gilardoni 43mm stroke cylinder (Minarelli horizontal LC)
43.0 mm = Simonini 80cc cylinder (Vespa)
43.0 mm = Parmakit 80cc cylinder (Minarelli horizontal AC&LC)
43.0 mm = Derbi FDS/FDX shifter
43.0 mm = Puch automatic
43.0 mm = Tomos automatic
So where do I find these Parmakit 80cc Minarelli Horizontal AC cylinders? What other cylinder options do I have? Welding up the old cylinder stud holes and tapping new ones isn't out of the question either. Looking for a good chance to take advantage of case induction, but without going to watercooling.
