Here is Adelaide South Australia fuel is between $1.40 & $1.60 depending where we are in the weekly cycle. That's just for normal unleaded not premium.
I use my bike for commuting more often than not & my average is 250-260km till reserve. I tend to ride in fifth gear though so my revs are about 2800 @ 60 km. If you are only getting 100km out of a tank with no smoke or fouling of the plugs then it can only be leaking somewhere. If there are not any puddles or stains under the bike where you normally park it it must be one or more floats or a leaky fuel line. Fuel line is easy to visually check while the bike is running (under pressure). If the fuel overflow hoses are not showing leakage at the same time whilst on the centre stand then I suggest that you remove the carbies clean them with some carbie cleaner, check the float levels & try again.
My gauge also shows reserve long before I'm even close to it in reality.

 

Just been lurking. Too slack too post.

 

Went out on a good haul yesterday. I was getting 360km on my first tank. Lots of hard driving on snaky turns and twice made it over 200km!! ****ing WILD!. When I filled it, it took 19 liters so from the 22 liters max, there was still 3 liters left in the tank. My reserve was on hard (like the needle was sitting as far left as it could go for 15 minutes) for 30 km. I was thinking it would die anytime, but it made it to the next drinking hole! I love this bike........

 

if u love this bike so much, why not get a cbr1000rr, to me these old girls are like driving the oldV8 holdens to the new hrt's (cbr RR's)

 

Thank you all for your comments, I will go check the fuel line,I do remember some three months ago I had a very little leak right in the hose that goes from the tank to theshut off/on/reserve knobwhich I duck taped (the way of fixing your bike here in Mex), I will check that spot and see if the duck tape wore out, so I would need to put a fresh piece of tape (...just kidding!!) will have it properly changed this time. But never realized that this tinny hole could let escape that much gas.

V's,
Luis

 

I don't know about Gill, but I wouldn't buy a 1000RR because its ugly and uncomfortable.

The 1000F is beautiful and comfy.

 

Yeah, I certianly wouldnt want to do a long haul on a 1000RR. The seat looks like a washboard and your *** would be pretty sore. I drove one on a test ride one time and swore I'd never get on one again......and my friend rides a F4i and its even worse!

 

I don't know how some guys can stand those uncomfortable seats. And I think it's way worse going from a niceseat like the 1000F has, tosomething else. If you don't know how a seat is supposed to feel, you just kind-of get used to the pain, I guess.

Oh, and for Luis, I can't believe you used duct tape on a leaky fuel line.....don't you know that's what gorilla tape is for? Gorilla tape is like regular duct tape on steroids. I have a roll hidden at work for emergencies.
