So basically I had an old 86' TRX 70 sitting around with a bad gearbox and no carb. Then a 125cc engine off of a pitbike. I started the build on Saturday and finished it up yesterday. Got to ride it for about 20 mins, running it through the gears, and took it on some trails by the house. This things hella fun, and pretty quick!! The whole thing can't weigh more than 100 lbs. I can post up the whole build and pics, or just a pic. and video of the final product. Would anybody be interested??
