There has gotta be something Wrong with my bike. It's a k7 600, 5w 30 oil, highest octane fuel every time, getting about 150km per tank. Is this normal? I remember getting 230ish on my first k7 so this doesn't seem normal to me. I don't red line at all, don't randomly rev my engine or do extreme anything. I like getting off the line with some brisk but nothing out of the ordinary. Thoughts?
 
Does your bike require the highest level of octane? If it doesn't, I would put what's recommended so you have a few bucks back in your pocket since your bike is burning so much gas.

The other basic things to check that relate to fuel: air filter, plugs.. when was the last time they were changed?
 
How big is the tank?

Every modern 4 cyl sportbike should be able to make 200 kms ish before fuel light comes on, provided you are riding it like it's a race.
Using the reccomended octane should help your mileage a bit, as an octane higher than reccommended will take longer to burn and provide marginally LESS power.

Does the bike have a power commander that might be dialed in really rich? I have a buddy who put akro full system and Power COmmander on his ZX10 and lost almost 15% of his fuel range, and had a sooty tailsection. He swore it was tuned right , on a dyno, by Ryan Gill when he was at Rider's CHoice. But for me, A n example, I'd perfer to have 160 hp and 200+ km range instead of 175 hp and 155 km range.
 
first I've ever heard of 5w30 oil being used in bikes. Isn't that a designated automobile one? Might want to look into what the manufacturer recommends for oil.
 
How are your brakes/calipers?

Is this 150km when your fuel light comes on? Most bikes fuel level indicators are notoriously inacurate.You might be surprised how much fuel is really in the tank.

Best to write down the odometer, ride till you need to fill and go gas up, take new odometer reading - old odometer reading, divided by # of L you just filled, and you have your KPL. Multiply that by the size of your tank, and you know roughly what your actual range is.

LOL.. ...ROUGHLY what your ACTUAL range is?

Sort of like saying ALWAYS and SOMETIMES in the same sentence.......SOmetimes we always go to Port Dover for Fri 13th,LOL
 
My Fiancee' has a k7 600 and she gets more then 150. I beleive she gets about 200 - 225, depending on how she rides.

I get around 185km and I own a k8 1k.


Fuel Economy also depends on driving style, tires, and ergo.
 
The 125 kms seems awefully low.

I have a 600 katana, and I got 125 miles to my last tank, that was with 1/2 old gas, soem spirited riding and I think I am running a bit rich. All highways and some pretty cool mornings.

Typically I will be 150-160 miles per tank

First and foremost, this thread is useless without the actual fuel consumption figure in L/100Km or at least mpg if you insist on medieval measurements.

5W-30 oil? Is that what the manufacturer recommends?

Not only that, but lower octane fuel should theoretically improve the mileage. Less anti-knock additives = more actual fuel to burn. Also, regular usually has higher percentage of alcohol which should improve combustion if I'm not misinformed. Bottom line, unless your engine is knocking there is no valid reason to use higher octane gas.

what does ergonomics have to do with fuel economy?

The higher the speed, the more ergonomics have to do with fuel economy. Seating position, rider height, windshield shape can all significantly influence already poor aerodynamics and induce drag, adding to fuel consumption.
 
Your bike is clearly failing, time to get a new one ;). 250kms for me on 08 GIXXXXXXXXERRRRRRRRRRRRRRRRRR 750.
 
any weight gain in the off season?
That extra 30 lbs might be slowing you down.....


:D

This ^. I have a PC5 on my R6 right now with just a custom map and the fuel mileage is really bad, my light comes on around 160 but I don't exactly try and save gas either..

We are talking about street riding, not long term, high speed, high RPM running where aerodynamics come into play.

for regular street riding, the mileage difference between a 100lb rider, riding in full tuck position at all times and a 200lb rider sitting straight up would be negligible.
 
I have a K6 750 and I see on average 200-220 KM's/Tank before the gas light starts to flash...
My bike takes 10w40 as per factory spec. I thought the 600 would be the same? (that is not something I would neglect)
The manual says that it requires at least 90 pump octane, not sure if the same applies for a 600 but it's worth a look into...
