I have a new to me 2003 honda vfr800 with leo vince slip ons and not sure of any other mods. It came with a PC III USB. I purchased the bike after the previous owner had let it sit for a few months. I ran seafoam through the first couple of tanks. I was getting low mileage (mid 20's/gallon) so I figured it may be the map in the PC III. The original owner had it dyno'd to his specs and the bike was pretty fast ( i uploaded it to the download section on the forum so others can take a peek, too!), so i figured he had it tuned for performance. I loaded the generic map for leo vince slip ons from the power commander site and got about 5 mpg more. So my questions are the following: 1) is there any map that will give me some better mpg? I don't care to go 100+ mph, but would like the reported mid 30's low 40's everyone else seems to enjoy 2) Is the cozye map everyone has a boner for good for my needs? 3) Would a zero map be okay to run with the slip ons? 4) Is resetting the throttle position in the Power Commander software helpful if a bike has been sitting for a while to kind or reset a "0" point for the rest of the mapping? I am very new to a larger bike with more complexity (my first was a suzuki tu250x). I have an appointment with a shop in a couple of weeks for a tune up. Perhaps my plugs and air filter are not so happy right now and that could be the reason for decrease in mpg's. I'm also getting new tires then as well, that may also help. I know it's a lot to ask, but I'm trying to do right by my investment. Thanks in advance!
