I have tried, was suposed to be finished doing all this by last Sunday but air filter went a stray i was also lied to by the seller saying it had a K&N and it doesn't it has a standard one that looks like it needed changing 5k ago

just trying to get it to a good state before its MOT in may and my trip down south next month

sounds just like mine as i get on av 90-110mile befor light comes on and my bike is alwase well looked after. like u said its not normal unless suzuki changed somthing on the k4+ bikes to the k3 bikes in the fule tank. mabe moved the sensor down in the fule tank or somthing but i dout it.

^ i think im going to clean up all the connections to the tank and see if that makes a difference, they most likely haven't been unplugged in the last 7 years but more than likely have gotten wet

and yes the sensor bounces on and off for about 15 - 20 miles

It does if you change down doing it, but the main thing that makes you get through fuel is using the throttle as an on-off switch, rather than being steady and gentle, and observing so as to not need to brake/gas/brake/gas. A bit boring, granted, but it makes everything come together!
Now stop wasting time and buy a new air filter. 200 miles and you'll have spent the extra on petrol anyways!

^ i have brought a new filter about............12 days ago and it went missing in the post, have another one on is way though so hopefully it will be hear tomorrow

PS after i Hoover'd the air filter and did the oil change, new pads and brake lines and 16mm tank risers im getting a hell of a lot more mid range and i mean a hell of a lot the bike is now picking up the front in 2nd it wouldn't do that before , now i was obviously not riding economically but hopefully i will get better mpg as well im willing to say its defiantly the air filter thats to blame (and maybe partly me )

My K3 didn't have a flashing fuel light, it came on at a solid fuel light with ~ 2L to go!

FWIW... There is no need to go out and buy a new filter every time.

Blow the old one out with bulk air - not one of those little blowers. I use a 1/2" barbed end (effectively an open hose) as the nozzle from about 6-8". Air cleaner should be good for 60-100k km providing it doesn't get wet with either water or oil.

i dont have access to compressed air and my air filter has done about 17k mile's just going to replace it as its the easiest option

You are right. A hoover or air line will get most carp out, if the filter is clogged up it needs changing. They aren't exactly the most expensive of parts. Oh, BTW, when was your oil filter last changed?

RE. Mattcollins - some bikes have foam filter elements and they need to be oiled. For those who have them.
