I almost fell off the chair laughing when I heard this one, cause I had the same ideas you did! Well, my good ol Cag 47cc bike broke down, and rather than just toss it, I took off the front fork and tire and put it on the Razor. The disk brakes stop on a dime and handling is superb. In regards to increasing power output, theres not much you can do. I actually tried taking all the electrical compeoneentes out of the Razor and putting them into the empty CAG chassis, but that didnt work out too good. If you are serious tho, I'd say get a better gripping tire for the back, a smaller sprocket and chain to increase power to the rear, and if possible, swapping the bulky drums on the rear for a disk. Dont rip off cables tho, as I discovered in the disk lever there is another cable that works as a clutch (disconnects power to engine) when gripped. Try experimenting, these things are fun to tinker with. At my forum (private message me for more info) we race those Razors in parking lots and driveways in our own racing series.
