I've found myself looking for a sixth gear for years. Would be nice. I don't think there's enough room.

I'm running a KZ1000P-9 on stock rims. I changed my rear sprocket from 41t to 38t to reduce my revs at 70mph & improve my fuel economy (I now get 15-20 extra miles from a full tank). Front sprocket is standard 15t.
At 70mph I am at 4000 rpm. Before I changed the rear sprocket, it was 4300rpm at 70mph.

I know what you mean. There's nothing better than opening up the throttle in 3rd gear to get past anything fast!
40mph to 90mph in two twitches of the sphincter!!! :woohoo:
