I took my schwinn stingray occ bicycle and cut up the frame, rewelded box steel to it and put a honda gx200 clone on it, i've had this bike for a while, and i just bought a torque converter for it, i used to have a centrifugal clutch on it, but it would break all the time. the engine's governor has been bypassed, and it now has a K&N style air filter with a red foam prefilter. when i had a centrifugal clutch, i had a 35 pitch chain drive train, i always had problems with the chain being too small to handle the power from the engine, so when i bought the torque converter, i upgraded to 41 pitch chain and a 54 tooth sprocket. i am also doing a hydraulic disc brake conversion on the rear tire, before i had a crappy mechanical disc brake from a pocket bike. in the pictures you will see a stone between the engine and the frame, i put that there to judge the distance that i have to raise the engine for the torque converter to fit. after i took these pics, i bought some more box steel and started to make the spacer, i am using 1in by 1in box steel with 4 1/2in thick bolts, i am placing 1 bolt between the engine and steel, the mounting bolts will go through the engine, bolts, and the steel before bolting the the frame. i am only 16, and ive done almost all this work by myself. dont pay attetion to the camera date, my camera got messed up the oldest pics are from 2011, not 2007.

yea, i was looking at a bigger cam, billet rod, flat top piston, small head, bigger valves, and electric start. i can get a billet rod for $60

You just need to remove the governor,,add 18lb valvesprings,,GX140 atomizer,,#90 mainjet,,foam airfilter and custommade open exhaust headder and itll be flying already with redline going from 3600-over 5000rpms easily.....The total of all mods the same $60..........

I already have a K&N style air filter with a foam prefilter, and i made a custom straight pipe with a muffler adapter on the end of it, since i have to raise the engine for the torque converter to fit i have to remake the straight pipe. and once when i tear open the engine, i will remove the governor, and replace the stock rod with a billet and a flat top piston.

The tires can handle the power, but the frame at one time cracked in half on opposite sides, i had to pull the frame back together and weld the cracks on the front and back, then, i made a brace from a strip of steel, and welded the brace over the welded cracks.

here is a little update, i made the spacers for the solid motor mount, and i welded a piece of steel on on the frame over the old steel. I started to make the slots for the motor mount, but my cutting wheels for my grinder have gotten a lot smaller from being used, so, i have to buy a new one tomorrow to finish.
