hey guys i've been doing some research on how to make a 50 go fast and i've came to the conclusion that i want atleast 100cc's cuz im a bigger guy and enjoy minis' lol

well the part im confused about is the cases. are the 90cc cases stronger then the 50s'? would it be cheaper/easier to take my 50cc engine to the machine shop to get it bored for a bigger crank and cylinder? or would it be best to sell my 50cc engine and buy a 90cc to accomplish this?

i dont race this is just something i wanna do to cruise the gravel rodes and be able to somewhat keep up with my buddies on full sizes. i have to take the quad with me when i go down to ride and it fits nicely in my suv and i can get it in and out myself which is another reason i like it:D its just really slow at the moment so i guess im going for more speed then anything cuz the take off power is descent.

heres a couple things i've done to it so far and its not fast enough but definitly faster then stock!

107 main jet
