what is your adverage mpg? how many miles can you get on a tank?
Spooph, you always detailed, page-length responses! Why am I feeling the urge to grab a 1 gal gas can?Depending on how nitpicky you want to get about this, here are some figures:
The stock tank will hold 4.8gal. Considering the bowls, fuel line and such, you can put almost 5~5.1 gal in the system at one time.
As has been posted, the gas gauge is horrible at being accurate. A lot of people post that their gas gauge reads low. I thought mine did too until I started filling the tank to the top. With the bike level (while sitting on it), fill it to the filler neck. Then keep filling. It won't fill up as quickly as you think, in fact, it will take a BUNCH more fuel.... ONLY DO THIS if you plan to ride the IMMEDIATELY, otherwise you'll just waste the gas from the overflow tube once you put it back on the kickstand.
What is your gearing? Where in the RPM range do you cruise? I have 15/44 gearing and tend to cruise speed limit + 6 or so, which means I'm rarely HARD on the acceleration. When we go for a canyon run the bike works 30% harder, with RPM's never dropping below 9K. This gives me an average of close to 60mpg, maybe 58 or so, never below 55mpg's....
Your riding style. When accelerating, do you take your time accelerating up to the speed limit, maybe holding the RPM's higher than they need to be for more than 2-3 seconds? When I come off the line I tend to give 50% - 75% throttle and quickly shift through all the gears to top gear at the speed limit + 6.....
How much do you weight? Do you carry extra weight with you on a daily basis? How much? Where is your tire pressures at? How well is your chain lubed? Are you provided with nitrogenated fuel or good old fashioned unadulterated, un-cut gas?
As Zandit mentioned, your engine is still settling in, so you'll see some benefits from there as well. What is your goal for MPG's? I have put 300 miles on a tank before. Your best bet is to get a 1 gal gas can, fill it, strap it to your passenger seat, and go ride her till she's dry....
I use my ninja 250 every day for a 100 mile round trip commute mainly motorway riding. The best i've seen is 105 mpg, the worst was 46.5 mpg riding at 80-100 mph. The overall average is 72 mpg. Thrashing it around twisties with the wife on back 4th gear against the rev limiter, I managed 60mpg. The longest I have gone between fill ups is 260 miles for 3.38 uk gallons. the bike will be 4 years old in a month and has just done 55,000 miles.From just above the Emark to the steel thing in the fill up area I can pull ALMOST 300miles if I baby it But what's the fun of babying a sports bike? haha, so I get about 200miles per tank until around july\august then I get in the 280's. Not sure why but my bike HATES winter mix fuel.
