you could probably use the current fuel for your scoot, but i would recommend 93 from local gas station, then do a reading on your spark plug.

I have heard good reviews from a few knowledgeable folks on 4 valve heads. If you decide to purchase one, make sure you not only get the head but also the piston that matches it. Using that head with the stock 2 valve piston is almost worthless. If not destructive. You'd be better off with a ported 2 valve head in that scenario.
