I personally won't be going anywhere near the top speed. I know the top speed they give the GS750 bike is 130 MPH, but that must just be because it redlines in 5th gear. I had a custom 28 tooth #630 chain sproket made so I'm probably geared a little lower (original rear spocket was 41 tooth), so your 120 might be right on! I'd say 100 mph is probably the top speed because of all of the extra rubber I have on the ground (drag) -- but who knows. Maybe I can find a dyno that will let me wind it up on.

I don't plan on going very fast because I don't trust my welding job yet. I don't have any welding inspection equipment, or the experience to insure all my frame welds have proper penetration, etc. I've done a lot of welding, but this is the first welding job that prevents me from road rash -- hopefully I did a good enough job.

How fast ya think it'll go? I'd say about 120 if you could handle it. When you get it done, take it to a local drag strip just to find out. Get a cable off a larger bike, if not that, splice 2 togther with some kind of conector/mount mounted halfway and attached to the frame, of course, only if you cannot find a longer 1.
