91 Night hawk 750. I jumped up one tooth from stock and this helped lower the RPM at highway speeds, but not enough for me so I bumped up one more tooth, and I'm happy with that. If your running 55 to 65 mph and you want to make a pass, I have to notch it down to forth. Around town I was really pleased. The taller gearing allows the bike to stretch out between shifts especially between 1st and 2nd gears. In 3rd gear I can run at all town speeds with out any further shifting. One thing that made a big difference was doing the Tim Hodge exhaust modification. You can Google it. It only cost me 1 can semi gloss paint and 8 stainless steel Pan Head screws. I drilled 5 -1/4'' holes in the baffels per the mod. I gained more low end power and better economy. The bike averaged 40 mpg, some town and country roads conservative riding. The mliage jumped to 45 mpg with riding the bike hard! The sound level is a little bit deeper, but lets face it, the bike still sounds like a wuss. I have checked the spark plugs and they are normal gray color. So overall with the sprocket change and the exhaust mod, I'm real happy with It. Good luck! Hondo.
