This is my King Motors 30.5CC baja, cost about $1,400,oo and, i modded it out, new alloy parts to replace the plastic, Heavy Duty parts, upgraded to fit my style, and, a deadly machine it is. I bought 3 speed transmission, and alot of upgrades, it has 2 boost bottles, and 4 bolt 30.5CC ordered seperately, and i added custom made tire chains, since it spins a lot from it doesn't get great traction on snow, so far, i am impressed. I show some of the parts i bought, not all, and the video of me doing a little bit of a run with it, i think it turned out great.
I had a few parts fail, from the high torque, and wieght of it, it wieghts about 40 pounds now, and it is a machine, that seems to have alot fail, due to weak parts, so, i just gonna keep adding replacements till i get the right parts to take the abuse.
Non the less, a good hobby, very fun, and this machine, is sure to turn heads, very loud, and awsome to see going full out, just make sure, ur not in it's way, cause it is sure to snap legs if it hits someone.
