A cam is definitely worthwhile so is lightening the flywheel. IIRC they weigh about 38 lbs stock yet reportedly can be cut down to about 16lbs. My machinist lightened mine to 19 lbs and the acceleration was great.

trouble is I speak English and I don't know this language, what do the symbols represent? :D I suppose it might be quicker & easier to just weld up a truss and test it out :D

Merry Christmas to everyone :) and have a very Happy New Year :)
