Know your product....The XS1100

[Jonesy]

All appears to be working ok I ran it down to 1/2 on the fuel guage, filled it again and have put another 240k's on it and guage is indicating about 1/4 to a 1/3 of a tank. I'll run this tank right out and see where reserve is

Thanks for the reply Jeff.
Havent actually ridden anywhere since initial test ride to suss out the new tacho. In actual fact I plugged in the old/good guage with the new blackbox and it max'd out too. The fuel in the tank is actually about 3/4" down from filler neck on the centre stand so I'm going to give it the benifit of the doubt and run the tank out and see if the guage moves accordingly. Rather live with an inaccurate guage than rip open two neatly sealed clocks to do the transplant. going for a ride next w/end so see what the fuel guage does then

View the link that Petejw1966 posted .It shows the fuel meter removed from the tacho and also show points for adjustment.If all the adjustments fail....swap over the complete fuel guage from one tacho to the other.You have nt said if the fault to full scale is regardless of what volume of fuel is in the tank or whether it eventually does change or is it just stuck in this position with the key on or off?The guages are nt remarkably accurate,they are a general guide........but with checking and setting up known values according to the book, regarding the level switch inside the tank, is a good starting point..........followed by replacing the meter should get you close to where you want to be.

Well I swapped the black box and wiring from good fuel guage to bad fuel guage and it made no difference bad guage is still maxing out to way past full.
any other ideas?

[Jonesy]

I was just about to say dont answer that ....I went and had a look for myself,  but you beat me to it

[excess.11]

It does.

[Jonesy]

Thanks for the replies fellas,
Jeff does that little black box and wires just unclip complete and clip onto the other one?
 plug and play so to speak.

The wiring and  connector on the tacho ,  part terminates to a small black box which is a regulator for the fuel guage.Swap the wiring loom off the faulty tacho that has the  operational fuel guage to the one you have full scale deflection on.

i just had a look at the 80 standard i picked
up a short time ago it has    X1000r/min  no idea
if its the original tho.

[Eveready1100]

Hi Jonesey. The tacho off my 78E 2H9 has the x1000r/min on the face, so I'd say yours was the original. Haven't got another one to compare, though.

[Jonesy]

yeah electricals not my favourite either, been knonn to let the smoke out of multi meter leads checking battery Give me a set of spanners any day
Bikes running pretty good just doing a few bits here and there to it

[petejw1966]

no worries,
unfortunately electrical isnt one of my strong points.

hows the bike running?

[Jonesy]

Hey Pete
Thanks mate, I just got off that site and it is a very good informative thread. although they dont really mention failure modes, but I guess repair and parts are very well described and identified.
was still hoping some of us locals had the knowledge to answer some of my Q's

[petejw1966]

hey jonesy,

one of the guys on the .com site did a bit of a write
up regarding the fuel guage, heres a link

is this any good..

Heres one for those that really know XS11's.
Topic: The  Standard Tacho/fuel guage.

Recently got hold of another tacho for the XS to replace the "whacko tacho". There is one very slight difference between the old and the new that you can see.
What I assume is the original (hard to tell with these old bikes) has written on it at the bottom of the clock X1000 r/min. The replacement has X1000rpm. The replacement tacho is heaps better than the old one, only wobbles about +/- 500rpm occasionally as opposed to  going from zero to right round to the fuel guage. The down side is the fuel guage reads past full hard against the stop. Tank has about 50k's used from a sidestand fill.

Q 1. can you tell from the X1000r/min and X1000rpm what model they are off (mines a 78E)
Q 2 Are there any subtle differences in the electronics from model to model to make the fuel guage behave this way. The fuel guage from whacko tacho is very accurate.
Q 3 Is there a fault in the guage to make it max out
Q 4 can it be repaired
Q 5 Can the good guage be removed and swapped into the good tacho.
