1990 zx6 at 55mpg

I recently purchased a 1990 zx6 with 30,000 miles. I downsized from a 1000cc yamaha. I have put 3,000 miles on this bike since purchase a few months ago and have been averaging 40-45 mpg. This is with commuting, alittle touring, and some spirited riding up the canyons.

I have decided to ride year round and want to get the max fuel mileage I can while commuting to work. I have been considering trading my bike for a ex250, but decided to try and see what I can do with this 600 first.

My commute consists of 11 miles one way. I ride home for lunch so I make this trip to and from work twice daily (44 miles daily). The commute is half city and hi-way but the hi-way does have a couple lights installed which really sucks for mileage. It has been between 15-40 degrees over these last three tanks so no ideal conditions for high mileage but I have been able to get 55 mpg over the last 3 tanks.

I have made no modifications to the bike, jetting, gearing, or aero. I get into a full tuck over 50 and cruise at 62 mph while on the freeway and usually 30-40 in town. Tires are 36 psi front and 40 rear. I will keep this updated but I really think that as the weather warms up and with some gearing changes I can get over 70 mpg out of this bike commuting. If this is possible I may forget the 250.
