1150 tank on an 1100 - fuel gauge calibration

I recently bought a low-mileage 1100 which has an 1150 fuel tank fitted, looks nice and gives me an extra five litres, but the fuel gauge is all to cock as a result, showing reserve after about 20 litres. Anyone have any ideas how I can get the gauge to show the correct reading? Don't know if the tank has the 1150 float in it, but assume that is the case. Don't want to start stripping out vast amounts of electrics if it can be avoided! Thanx in advance.
 
The extra 5 litres is a clue:augie

You'll need to bend the float arm to give a 'slightly' more accurate reading for the last half of the tank but will find the guage won't move very much during the first half.

If it's an Adv tank and had the Adv sender in it then the fuel gauge would read correctly. The RIDs are all the same - it's the sender in the tank that's different between a standard and Adv tank. So you must have an Adv tank with the original 1100 sender and that's the cause of your problem.

Short of experimental bending of the float arm you could solve the problem by fitting an Adv sender unit. But they're quite expensive, I think.
 
We did the same Mod 1150 Adventurer tank on our 1100. The gauge is out but it has advantages. Simply ride it and watch the bars drop (odly ours never lit the top bar) when the light comes on you have 8 litres left about 80-90 miles..... easily enough time to find a fuel pump...... even in Patagonia.

The cost of the adventurer sender is bonkers and does nothing for you. My advice is keep it as it is

Hope this helps

Thanks for all the advice - will leave it as it is I think, under the circumstances, I just get a bit OCD about fuel, as I managed to run out of petrol on my first trip on my previous 1100. On the forecourt of a closed petrol station. In the middle of nowhere. At night. :blast

It's an Adventure, not an Adventurer..... well, someone was bound to say it, it might as well have been me. :D

With an un-modified filler neck I've never seen the top bar lit on the gauge. If you drill the filler neck (to gain an extra litre or so of capacity at the expense of expansion space - only advisable if you're going to ride the bike immediately after filling up) then the top bar does get used.
 
Thanks for the update on the bike name :)

A little off topic but..........
To be honest the whole upgrade of the tank is a bit of a urban myth. In UK or Europe there is absolutely no need for the large tank, And even in some more remote places its only for mental comfort rather than a necessity. On our travels we only needed the extra fuel once, which was on the Dalton. Even then 5 litres in a plastic bucket tied to a pannier would have been more than enough the rest of the time its just a big heavy lump which stops you taking more necessary stuff.

Gauge

Just reset the trip on the speedo when you fill up and keep aneye on the milage give you an idea when filling up is required. If it goes on reserve that quick must be have the 1100 semnder in it.

With a drilled neck and a tank filled right up to the top, by the time you've been into the kiosk, pee'd and paid there can be fuel flowing out of the overflow. Worse if the bike's in the sun or it's a hot day.

So when I say 'ride the bike immediately' I mean just that - not 5 or 10 minutes later which many people do when they stop for fuel.

That depends on many things - I guess you're basing that statement solely on the availability of petrol stations. On that basis, in the UK probably no-one needs a tank larger than 5 litres!

Having a big tank is about giving yourself options when doing distance - whether to fill it or not. Whether to stop after 200 miles or keep going for longer because you want to. Whether, in an 800 mile day, you want to stop twice or 3 times (or 3 or 4 times).

Next Wednesday I have to reach Pau from the channel coast and my stops will be governed by the range of my standard tank. I would much rather have an Adv tank so that my stops could be governed more by my bodily needs - having more fuelling options does make a difference even if it's not essential in terms of availability of fuel.

At the other end of the scale my weekly commute gives me 4 days out of a standard tank, but just a couple of litres more would allow 5 days. I wouldn't need to fill the tank right up to achieve that, but it would be nice to have the choice.
 
Jeez:rolleyes:..this is the technical section, not the opinionated bigotted section.:D

The guy's bought a bike with the large tank already fitted and only wants to know how to get the fuel guage to read accurately:comfort

A true Tosser is only concerned about size - tanks, pies, bellies, panniers and such things.

Oh, and oil :D
 
I do a lot of work-related miles in the summer, the last two days have been a 150 mile round trip daily, got a 300+ miler next week, 200+ miler the week after, so it does mean less fuel stops with the bigger tank. It is a bit of a pain resetting the trip-meter as I get to claim mileage, so end up having to scribble down the miles before the off. Short term memory problem? Sorry what was the question? . Not a major hassle, was just merely curious to see if it was a big or expensive job. Again, thanks for all the advice!
