The wife and I put on about 125 miles today and burned up 3.8 gallons which averaged out to be slightly below 33 mpg, mostly on the highway. Prior to the cam and map changes, I would have gotten roughly 40 mpg under similar conditions. Admittedly, 125 miles doesn't tell you a lot but it seems pretty obvious that fuel mileage has taken something of a dump. Bike runs well but very cool (based on oil temp) which makes me think that we're running excessively rich. Will check the plugs tomorrow and depending upon what I find, I'm going to give V & H a buzz on Monday and see what they have to say about this.

Cheers,
Dave

Hi Dave.

Checking plugs on a F.I. is not going to tell you a lot, unless it's way out of wack, it is far better to do a dyno run, that will show the fuel curve under load.
