Default New guy w/ ??s

I've been thinking about getting one of the "80cc" chinese kits from Ebay. Just stock isn't in my vocabulary. I figure I'll match the intake and exhaust manifolds to start. New plug wire. And throw on a 36 tooth rear sprocket. I only weigh 150# and nearly all rides will be on flat terrain. Trips to be made at 10 miles one way and under.

What should I expect for top cruising speed(@ acceptable RPMs)? I would like to get 40 mph around the top, over a 10 mile stretch. Is this realistic?

Can these engines use higher octane fuel for increases power? What does 100 octane do to these motors? Blow them up from knock? I'm guessing that the octane boost doesn't do much for a naturally aspirated motor?

Has anyone tried either alcohol or water injection? Here's a link if someone can relate their experience or expertise to the subject. H20 injection can produce more HP at cooler temps and increase fuel mileage, believe it or not!

This is a great site. I had to sign up as soon as I found it. Thanks for any info,
