yeah, i guess a bigger kit
what kinda kit are you going to get thats a 50cc that you couldnt spot for the 70cc tccd?
your style of carb will depend on your manifiold.
Im not saying it wont work, but thats allotta carb for a 50cc.
There are exprerienced tuners out there that could make that setup work, but i bet it would be easier for you and i to use a tccd 70cc kit and the 21mm intake
also, any performance exhuast will fit a magnum once you take off the slant port head and put your kit on.
Thats kinda whats got me wondering. A magnum cylinder is a pretty good head. With a little porting i dont see it being to far off from the tccd 50cc ( maybe you found a source of 50cc kits but all i know of is the tccd ones im sure there are otheres in europe )
