Two things, gas mileage. My speedo is off about 10 mph so I guess the odo is off too but it seems (Nighthawk gets 60+ mpg) that the GS is like the Norton (that got around 35mpg) and gets around 30-40 (I am running a pipe; yoshimura front and kerker back) and the power band is kind of weak under 3 grand on the tach (I think that's working okay). I caulk this up to light flywheels. 1st, 2nd and 3rd you can short shift all you want, the motor will do anything but 4th and 5th need to be treated a little different; shifting out at a little higher rpm and with my tall gearing I find myself wanting 4th on the highway occasionally if I have to blast away from an idiot.
My three major questions are mileage, low end and muffler. Can I use a yoshimura, like a RS3 type, and have a quieter bike. Or is there any smaller (in size) quieter slip-on)), one could buy?
Thanks, Rick
