OK, I've done about as much research as I can on this forum, so time to drop the question...
I have an 81 XS400 that currently is running 16/37 gears with a 16" rear wheel. In 6th gear, it runs about 1:100 (I.e. 60= a hair over 6000 RPM). As I do quite a bit of 55+ mph riding, I'd like to calm that down a bit. xschris said on one of the threads I found that he's running a 16" rear with 17/37, and at 60 was at about 4800 RPM...
So, can I really lose like 1400 RPM by gaining a tooth up front?
I was thinking of going 17X36...would that be too much? I don't really hot rod it around town, and would prefer to keep the RPM fairly low on the highway (i.e.60-70 MPH). I realize it's a 400, but this is going to be my main bike this summer, so I'm gonna need it to keep up...
Mechanically, it's stock, with shorty glasspack mufflers and rejetting.
