I'm going to be doing almost all the upgrades you described--
but, against the advice of the experts, I want to gear it LOWER instead of higher---- wheelies, smoke shows and rapid acceleration.
I might only hit 40-42 mph, but I'll be going like a bat out of hell when I accelerate.
I'd like to have a moped that pulled the front end up, without even trying--- Every time you gun it....get a little lift in the front end.
I know it's not too smart--- I'll overwork the engine, hit max rpms too soon, I'll have to be careful not to hold it at max throttle.... probably have to redo the rings after a season....
But think of the low end power--- hill climbing dream--- not to mention taking off like a rocket.
I'll see if I can get to the rear sprocket tonight--- I'll be posting some pics as it it.
