I joined QR just because of this post. I gotta know how it all worked out and how this thing runs!
I'm sure it's gotta run on 110 or greater, I'd say she's gonna have plenty of compression. I'm building an 88 motor right now. The faces where the cyl bolt to the case on mine are a little scarred up and I've been gathering info on how much can be cleaned off of each cyl land and what head and port mods must follow. Found a must read for everybody (since it's free) http://www.datafan.com/Horsepower_Blog/gordon-jennings-two-stroke-tuners-handbook/
Check it out! Loads of info. It's got slot of the formulas. Also I have an LT manual here if y'all want me to look anything up.
