I have a 01' Katana 750 with a M4 slip-on. I have two questions, one is how can i further increase horsepower and top end speed.
Secondly, The bike recently started to drop in MPG, i've put about 1500 miles on the bike this year so far and overall it has 6200 total miles on it. i found myself at the pump at around 140 miles rather than the 170-190 i used to get, could it be that the bike is just breaking in now or could there be a problem with my fuel lines? I really don't care if the miles drop, its just i don't want to be driving with a problem and end up breaking somthing else
