Re: not to impressed with first kit looking for upgrade
now heres the deal ...
you can spend 600$ on a dax balanced motor, a puch hi hi head, an reed valve kit and 3rd transfer port jug, a larger carb, a ramped cut ported piston, upgraded hub adapter, and have a fast kinda powerfull motor that will require constant tune ups.
you can spend 600$ on a denardis 50cc air cooled motor and have tons of raw power and reliability, and rediculous speed, but must custom weld mounts on your bike.
you can spend 600$ on a preddy 212, aluminum fly wheel, carb and manifold, degovern it, vale train mods for the higher rpms, and a cvt trany,..... and have the most rellable fastest torque monster bike around, but you better know how to build an engine and custom mod one to also requires custom mounts and proper gearing anf tunning of the cvt.
all of thease can be had for the same cost of tossing money at a garbage china girl to go fast . in the end you could have just got a way better motor for the money you spent.
