I have only put a few of hundred miles on my '05 RIII since I bought it but it has already become clear that this thing is a gas hog. My first mileage check was 24.5 mpg.
I rode conservatively to try to see what the bike would do when not pushed as far as gas milage goes. The speeds were around 55 to 60mph on secondary roads.
It had the CAT bypass, TOR pipes and a Power Commander (which I can't tell you anything else about except that it's "in there". I know it has also been screwed around with using a Tuneboy program. I think it was mentioned that it is "zero", whatever that means............
Any suggestions on the sucko gas mileage?
24.5 mpg is way too low.
I bought my bike with the TOR's and cat bypass and a stock tune. I was getting maybe 34-35 mpg. After a I put a richer tune in it using Tuneboy, the mileage dropped to maybe 30-34, depending on the season.
Do you have the Tuneboy cable? If someone loaded a Tuneboy tune into your bike, the license is specific to your engine - it can't be used on another bike - so whoever you got the bike from should give you the cable. If someone paid the $400, you should be aboe to use the Tuneboy software to read the key code for your engine and just buy a new cable.
You also have a PCIII on the bike? You need to upload the trim map from that PCIII to a computer so you don't lose the information. All you need is a USB cable, a laptop, and the PCIII software you get for free on the DynoJet web site.
Then, disconnect the PCIII and reconnect the cable from the injectors back to the Triumph ECU, remove the PCIII O2 sensor bypass and reconnect the O2 sensor to the ECU.
Then, have your dealer load the proper tune for your exhaust.
If you have or can get the Tuneboy cable and a laptop, you have easier options for either loading the stock tune or a tune from Tuneboy made for your exhaust.
