Hobbsy....I just converted a Maloney 100 to
CD ignition..Turned a 16-6 Zinger 7700 rpm, a 16-8 at 7000..
I had a 125 that turned a 16-8 at 8000 rpm..Most of the 125s I saw had out of round cylinders and poor piston rings..John Maloney was on the right track...If he had done a little more work on these, maybe a chrome cylinder without the weight of the detachable head and a better magneto, he would have beaten the little RCS gassers by many years....Isn't hindsight great ????
