Get a new Zuma 50 and mod the throttle stop. It will hit 40mph on the flat no problem. Think of it as an investment. When you sell it, you will get 50% or more back of the purchase price. $1000 outlay in the end for a bike that is new, quick and gets near 100mpg and won't break.
Hate gets you nowhere.
