[SLESTAK75]

I think that mine is a cheap knockoff of this one. The MXR Trailbender 160cc "racing" go kart. They said it only had the 58.5 head but I think it has head and bore. I agree that it has no climbing power. Mine has 16/32 sprockets. It goes near 40mph flat out until you hit a hill then all the speed fade quickly. I already went with 1500rpm contra and lighter rollers. Haven't tested on the road yet but on stands both pullies had full range of motion so seems like ill still have top speed, just hope this gives me better pull. I'll get the uni filter, orange cdi and coil, a12 cam, port and polish, iridium plug...I think I'll be real happy with it then. It came with some really crappy welds. The throttle connector broke on the first ride, its been rigged ever since. The front fenders didn't last too long. The round pipe they were made of was pinched flat where they connected to the body and that didn't hold up well at all. I plan to add some metal to some of the crucial welds so I don't have wheels flying off in the middle of a ride. All in all I like it. I will post some pics soon, as the one I put up was generic from killermotorsports where I bought it. That's all I've got to say about that.
