I got an '09 FZ1 (roughly 30k miles) a couple of months ago and it has been getting absolutely terrible fuel economy. I get about 70 miles before I get switched to F-Trip, which is (70/3.8 = 18.4 MPG). On deceleration, the bike pops a ton, and I think this may be more than normal, maybe like 10-20 times on one deceleration. The bike has some modifications like -1 front sprocket and a 93 octane tune (vcyclenut) but I am always trying to ride under 5500 rpm with the occasional twist to have fun. I also have a problem with the bike running hot (it idles a little high around 1.6k even when warm), where the temperature will climb relatively high even in the winter, so I am worried about what will happen in the Texas summers. I have already changed the air filter and plan on replacing spark plugs but I'm not sure what else I can do but maybe a dyno tune.
