It's not modified, it came that way. The 20 lb stator (or whatever size) stuck out too far, so it was removed for ground clearance and quicker revving.
Well I believe there were only 30 total built. I don’t think I’ve ever seen the number of survivors left in the world. So few that as someone else stated, Barber doesn’t even have one on display. They’re incredibly rare.
The Barber comment does drive the point home somewhat. That’s pretty nuts if they can’t even get one.
Yes but I’m sure it was donated by his family so that his genius could be on display and not lost forever.
A nice fellow named Nick Wargetz bought one of those. Supposedly you had to have a resume to order one but cash talked. He let me ride it once at TWS in practice. All I remember is it was brutally fast, a real handful on the rough banking at the time.
I think they might have more than one, one for sure was raced by Chuck Honeycutt for the Barber race team. I'd guess they bought that one.
I don't know that it was 20 lb, but 10 for sure. I raced a KZ1000J in V5 back in the early 90s. I ran it stock for the first few races, but after you lever the front wheel off the ground a few times with the Gen cover, you realize that this is the only solution. The bike actually revved quite a bit quicker with the weight of the end of the crankshaft. I took the cheap way out, by not pulling the crank and shortening the end, but that left the crankshaft susceptible to damage if you fell. Easy solution is, don't fall. The J was what this bike was based on. It was a handful with minor modifications, so I can't imagine what the actual S1 was like with essentially double the horsepower.
