I just stumbled across this board today. I spend most of my time over at Zumaforums.net
I bought this used 2002 Super9 LC a couple years ago. I also have a 2005 Zuma.
Here's a video a friend of mine shot after I first bought it. His indicated speed while following me on the highway was 56mph.
I have been riding it for over a year and just bought some new parts last weekend. Drive belt, Malossi Green Contra, variator v-bushings, air filter (previous one is torn up). I'm running 5g rollers right now which I think are a little heavy. I found that someone drilled holes in the back of the airbox. I would like to upgrade to the RS II pipe because it seems a little down on torque compared to my 70cc Zuma.
How many revs can the stock crank take?
