I am so pissed at my Bandit, 2002 1200S, that I am thinking of selling it. New left over 02 purchased in Sept. 04, got high 47-49 mpg. Added a Scorpion pipe and the milage stayed the same, but the header started turning blue. Removed the pipe, ordered an Ivans jet kit. Jet kit installed, wow!!!! Bike ran like a stripped ape. Milage went to a high of 46-47 mpg. This is OK with the power and how I like to get on it. A couple months later the milage dropped to 28 mpg!!!!!!!! WTF!!!!!!!
Found some carb boots loose, retightened the boots. MPG went to 31 mpg. Had the mechanic look at the bike, said all was fine. Last month took it to another mechanic, he adjusted the valves and said she is good to go. This is BS!!! To go from 46-47 mpg to 28, then 31 mpg just sucks. When I ride with friends I am always the one looking for a service station to fill up. I used to be able to go 160+ miles before I thought of a fill up. Now at 120 I know I have 1 gal of gas left. If this problem is not corrected I will trade the Bandit in for something else, I don`t want too as I really like this bike. This milage thing SUCKS!!
