poor gas mileage...
#11
my bike has 29,000 miles, a k&n filter and a slip on. gearing is stock, no power commander. like i said in the original post i just replaced the spark plugs, before i did it ran great and i was getting 42-45 miles a gallon every time. the plugs i put in are the same type i took out the iridium ngk's. and no mine doesnt seem to run any better or worse in traffic when its hot.
I'll get 180 out of a tank no sweat.....

People dont use motorcycles as daily commutes? It doesnt matter if its a cruiser/sportsbike/dual purpose/scooter, when you are getting <30 mpg out of a bike when you should be getting around 40 then theres a problem.

and thats my concern really, the fact that before i changed the spark plugs and fpr i was consistently getting minimum 40 mpg, most of the time it was closer to 45. im just afraid something is really wrong and if i keep riding it im gonna cause something more serious to go wrong. i also wanted to mention that there seems to be a lot of soot building up on the exhaust now too.

Was the FPR change due to fuel in the oil? I have an 01 F4i with almost 22,500 on it, a 2-Bro slip on, a K & N, and a PCIIIr. I have had it almost 1 month. When I first checked, it was getting about 37 mpg. I loaded the the stock MAP and since then I am getting about 40 - 41 MPG. I am going to do a plug change in the future as well as clean the filter. K & N says that the filter doesn't need cleaning unless you can't see the wire screen on the filter. Mine isn't that bad yet, but I intend to clean it anyway. How dirty is your air filter?
As for expected MPG, I expected to get upwards of 45. My 07 R6s consistently got 50 MPG. But as long as it's above 40, I can live with it.

i cleaned the air filter when i changed the plugs about 2 months ago. the bike started running funny, bogging down at low rpms and getting bad mileage and everything i read pointed towards the fpr, including the gas in the oil. but unfortunately nothing improved after i changed the fpr so now im kinda stuck. interesting update today though i jumped the connector to see about any codes and its telling me my vehicle speed sensor is faulty, but ive havent had ANY speedometer or gauge issues of any kind.
