03 Tiger with 40k miles on it. Lately the gas mileage has gone down to the mid 30's. Light used to come on at 200-210 and now comes on between 180-190. Bike seems to be running a bit rough at idle.
Valves are in spec. New plugs. Clean air filter.
What else to check? Throttle body sync? Can a dealer do a diagnostics check from the computer?
Thanks.
might be the oxygen sensor acting up. Tends to make it run rich.

I've had an 02 eliminator installed for the past two years.
I've heard a lot of arguments about how O2 eliminators don't really work.
Just something to consider.
