The only modifications I'm considering are a passenger seat and backrest (like the one from Hollywood Motors in Canoga Park, California), and a change in either the rear sprocket, or both sprockets, for better gas mileage and lower revs on the highway. Any recommendations there? I believe the stock front sprocket has 15 teeth, and some seem to think a change to 16 is good, but some think it's not a good idea. Rear sprocket, I believe, is 41, and there seems to be more of a consensus on switching that to 39.
I should be picking it up Labor Day weekend or the week after. I'm looking forward to getting out on some rides with it before the riding season here ends.

Welcome aboard!
There's about a 1:3 relationship between the countershaft and rear sprockets: going up one tooth on the countershaft is like dropping three teeth on the rear. I'm not entirely sure why people would recommend dropping two teeth on the rear rather than three. The 1000 shouldn't have any trouble pulling that ratio - maybe there's a vibration/RPM Issue or something. :huh:

However, those bigger diameter sprockets are slightly easier on the chains then smaller sprockets.
15/35 is still my choice for my bike.
Need to think about cutting out two links and back to 94 total.

I spend most of my riding time on the highway at the speed limit, so I like about 3500 RPM at 60 mph for my old Kaw and Honda 1000's and 1100's. My '81 KZ1000CSR was running at 4300 RPM @ 60 mph with the stock gearing. I changed it to run 3300 rpm at first, but that was too highly geared around town and required downshifting on the highway. 3500 is as low as I would go on the KZ1000....
My '83 GPz1100 seems to like 3800 @60 gearing....it has less bottom end torque than the 1000...., and I occasionally like winding it WFO...with the taller gearing it hits top speed at 9300 instead of revving past redline like it did when geared stock. I'm sure I'm getting it nearer 150 mph now (the speedo is inaccurate, so I don't go by that).
I'll sometimes change the gearing back to stock when I go to the drag strip...
