Hi i am wanting to make my 4 stroke Sinnis Matrix 2 (Chinese) faster, i have looked around the bake and i can see no obvious restrictions. I want to know how could i make it go faster the top speed i can reach is 55mph. I have been thinking about getting a new sports exhaust, air filter, rollers and a bigger jet. Would these make much of a difference or do you know anyway of getting it to do an extra 10mph?
There are many ways to improve power, big bore kit (180cc) cam, head, long stroke crank etc but your only going to make trouble down the line. Drive belt's don't last long on std machines, so improving power output will make matters worse! If you really do want it faster then internet has hundreds of parts.
