So when I bought my 1100 kat it had after market jets, pipe, and air filter. I've only had the bike on the road for about a week now and finally have it running good and noticed how bad my mileage is. A friend and I were thinking maybe smaller jets would make a difference. I have "138" jets in there now if that means anything to anybody and that's what was put in at the dealership when the previous owner took it there. He was told that "132" jets is what is suppose to be in it. So any advice to get more than 25 miles per gallon would be much appreciated
