2 strokes have long been known to wear out a lot quicker than 4 strokes. What about building a long stroke 1200 cc 2 stroke instead of a small 600 2 stroke. I envision a twin cylinder, opposed cylinder firing together to make a 'twingle' using crankcase induction. Maybe a 100mm bore and 200 mm stroke making about 1500cc. Revving to about 3000 rpm. The icing on the cake would be direct injection, but maybe simple is better. With such a long stroke and mid porting maybe very little port timing overlap may reduce fuel economy. On a different note, i am looking at patenting an electric reduction box that will also work as a hybrid, that should be very interesting as the model using rc electric motors I made is very interesting.
