Based on a project on scooterhelp.com, I found an old VBA and have decided to put a new PX200 electric start in it (as well as upgrade the front end to the PK, etc.). I am seeking advice on the motor... I definitely want to put a Malossi top end on it, and given all the extra power and the very light weight of the bike, what is the consensus on the upgear kits? I think I should be able to use very tall gears without a problem due to the upgraded, bigger motor in the smaller, lighter frame.
What about this Worb5 24/63 versus the regular Malossi upgear kit? Is it worth the extra money?
Also, I know want to stick with injection (sorry, boring, I know...), so what about the Mazz. cranks versus the Worb5 "special lip"? Since I am not going "all out" (reed valve/huge carb, etc.), does this seem worth the expense?
Finally, the lightweight flywheel should not be a problem, right? Based on the bigger motor/smaller frame...
Thanks for your opinions!
