Question Fuel sending unit

I read somewhere recently that later models' sending units were more accurate, and more consistent.
To which year models does this apply (if it's true at all)?
I have an 01, and I've had some intermittent problems since removing the tank for the first time (about 20yrs ago).
Thanks in advance for the advice/opinions of the listers

Say what? 20 years? The VTR isn't that old....

Either that came out wrong or I'm misreading...

Anyways... The sender unit is different from 01 onwards, with the larger tank (Europe only) and as far as I know have the same reliability... but that should mean that you have the "new" sender unit...

So it's probably not the design of the sender unit which is causing your problem... However, new or old, they can fail... test it, by clamping the vaccum hoses...

I've had the tank off my '03 at least a dozen times. The readout for fuel is dead bang accurate. When the red light starts blinking, I've got exactly 0.7 gallons of fuel left.

Ok, I have a Q not entirely off topic, but how many miles would you estimate there to be left in those 0.7 gallons when the red light o' death begins to blink? I know each bike is different, but just give me a guesstimate.

Supermarto;

It would depend what kind of riding I've been doing. I posted about a test I did "200 miles per tank?" a while ago. Holding 65 mph on the highway I got about 51mpg with about 36 miles on reserve.

Usually I get 44-46 mpg on the highway, which would be 30 or 31 miles on reserve.

For urban traffic or scooting in the hills, I get low to mid 30s mpg, more like 23-25 miles on reserve.

They probably changes to a different sending unit for the '02s on since they have the LCD fuel level readout. My '02 seems pretty accurate.

Anybody got a sending unit they'll part with for almost no $$?
