You could buy a real man's bike and not a geeky moped for a start.





If you wanted to make it faster, you could remove the engine, wear it as a dress, and run faster.
Reply:Port it. Make the exhaust port larger with a file.


Skim the cylinder head by ten thou.


Remove unnecessary weight.


Modify the exhaust, try removing the baffle.
