i just got my full fairing CAG (Gpmx3 or watever they call it) and it is one funniest ever built, well for starters the fuel tank was full of plastic chunks, fuel line fell off carb while shipping, and there is even a whole in the exhaust pipe that spits out oil at high speeds, wat do u think about it
be careful we bought bikes from there and the frames snapped between the swing arm and seat frame the bikes dont have a good support for the swing arm and they tend to snap
While you have your welder out, I'd say it would be a good time to go over all the welds on the bike, see about reinforcing them with gusset plates to make them stronger ...... Hell, maybe extend that engine platform out a little, and get it ready for a 110cc engine swap while you're at it ..... just a thought.
I dont think these chinese frames could handle a 150r motor. I've ridden my freinds and it rips for a small bike. Could you imagine that kind of power in a cag.You can get 90mph out of it easy. But the tires would disinagrate once you get over 40.
