hmmmm i lost mileage with dynojet too, dont know about mpg but i got about 120 miles to 10 liters before and about 102 miles to 10 liters after....I have the Maxair predator kit on my 1100. It was easy to install took about 3 hours. I gained the mileage I had lost with the Dynojet kit. I like the way the bike sounds, runs, and starts in all temps. I have rode it in all temps from 25deg to 110deg with no problems for the past 13k miles.
I highly recomend the system.
My bike also has straight pipes, ais removed and the fuel solenoids removed.
Hope this helps.
