The old girl's been getting a good going over since the trip to the rally.To date, I've replaced the leaky O-rings in the oil cooler pipes and have given the crankcase breather system the cleaning of its life. Jeez, there was some muck in there! Repaired the half missing head of the oil filter bolt and fresh, thicker oil with a new filter to top things off.
Been sitting around waiting for the rain to stop so i can get out for a comfortable ride to check that all is well. Was thinking of my oil loss scenario on the trip and the fact that my bike may have met the same fate as Christians if it wasn't for Steptoes insistance that we check it when we did, instead of my theorised check at about Moree, which would've been about my normal stretch between checks, which may have been too late at that rate of loss. It definitely was a shock to see how far the level had dropped.
I know for a fact that since the rally experience, virtually everyone is keeping an eye on the little window, just in case they get Xtianed! ( new word for the week!)
So I had a look around to see how something could be devised to give a warning if the bike suddenly starts using / losing oil ( or even if the sump plug has fallen out) BEFORE the oil pressure light comes on and it's too late.
So here it is. No devising or fabricating required. Just a minimal wiring run to hook up a factory oil level sensor fitted to the required XJ1100 sump pan, of which I have one now winging its way over from the states, which will go to a warning light I'm thinking of putting between the bar clamps.
I picked the whole sump / sensor up for just $100 including shipping so I reckon that's a cheap price for absolute peace of mind.
I'll keep you posted when the fitting time arrives.

Sounds great Errol.........although unlike a car that stays flat to the road most times...you might have to get used to the regular false warnings you may encounter due to cornering/riding lean angles.
Is there any info as to....... how far below max level it will indicate on?
How is the set point calculated?
Is the XJ1100 an identical sump pan regarding holding the same (or less) volume and why use this sump instead of converting the original XS1100 one?
-
I haven't got any specific data on them, Jeff. I did a fair bit of reading on the dot com site from owners over there and i haven't found any reports of false readings. I did read that the XJ's warning light comes on before the level reaches the bottom of the window, so should be ok for my desired purpose.
The sump is a direct bolt on though it may hold slightly less oil due to the big recess where the sensor is fitted. And to answer your final question, you can probably see why I didn't want to try adapting the original sump in these pics

It's an oil level sensor. When the oil level comes below the top of the sensor, it triggers.
Also, according to the XJ owners handbook, the oil capacity is 3.5 litres with a filter change so is supposed to be the same as an XS. Hmmmmm......maybe a tad less, I think
-
Errol....to avoid having another globe to add somewhere on the bike.....you could use a tricolour LED installed where the existing oil pressure globe sits.
As the plastic filters the colour to red on the existing globe.....by replacing it with the LED.....retain the red for the pressure..and use the blue...to make purple for the "level".

I like it!

Had one of those moments this morning, Jeff. I realised i no longer use the headlight warning light on the guage cluster due to the HID headlight so I could slot a nice bright red LED in that holder and revamp the wiring to suit.

Bit of an update on my project. Received the sump on Friday and between nightshifts, started planning the details...
(https://xs1100.com.au/forum/proxy.php?request=http%3A%2F%2Fi950.photobucket.com%2Falbums%2Fad349%2FEveready1100%2FXS11%2520oil%2520pics%2FScreenHunter_01Jun181112.jpg&hash=381a6b0206b8a3e755556b09473f4e36149453bc)
^ Inside view of the recess for the sensor unit. I'd guess at about 200ml in capacity lost due to it.

^ Where the sensor protrudes

^ Top edge of sensor is approx 20mm above sump gasket level, which brings it in line with the bottom of the window, so it will show low level when you have a sump of oil left, which should be enough to save your motor.
(https://xs1100.com.au/forum/proxy.php?request=http%3A%2F%2Fi950.photobucket.com%2Falbums%2Fad349%2FEveready1100%2FXS11%2520oil%2520pics%2FScreenHunter_02Jun011319.jpg&hash=afdb700f9ee1dfb96d23d384c7e53bee6a245955)
^ Sensor unit is a simple float affair which switches as soon as the float comes away from the top of the unit.........but............
due to the XJ1100 having a computer module in the dash that carries out all sorts of self tests at startup and while running, Yamaha have designed the unit to go open circuit when the sensor triggers instead of the normal closed circuit, like most warning lights etc. But all is not lost! After a quick discussion with my pet electrician at work, I purchased one of these dual mode relays, which can be set for either open or closed circuit operation at a cost of $15. This will be set to close the contacts for the warning light when the oil sensor goes open circuit and unloads the relay.

^ Relay unit
This will make the wiring a little more complicated but should still install pretty easily.
I'll have a crack at it this week between shifts and keep a pictorial step by step for anyone interested.

1st ive seen on this thread,
what a good idea.

Holy Shit Errol....................thats uncanny...........
Here i was coming home from work today ..............wondering......how Evs going with that sump/oil level setup.
And lo and behold...................there s your post..............fricken spooky......

May have to look a little further into this one, its certainly better to be safe than sorry when it comes to oil level. Not a fan of getting off and walking home... Guess it can go on the list along with changing over to an automatic cam chain tensioner, eh?
-
I took my sump over to Geoff's place on saturday morning to show it off and he noticed the marks on the bottom of the sump under where the oil pump pickup sits. I notice yours has the same faint swirly circle in the middle of the pan just below where the connector plug is sitting in your photo. Any theories on what might cause that?
The sensors opposite to the norm workings caused a bit of a worry until that relay type was pointed out to me. I didn't know they existed in that form, but now I know. The one I bought is a massive case of overkill as far as the loads are involved but the price seemed right to me.
My plan is to utilise the connectors where the Reserve lighting unit used to hook into the harness and fit a bright red led where the (now defunct) white headlight warning light resides. this way, I'm not modifying any part of the main harness. Just the add on bits which have already been altered.
Hobbsy, personally I'm not keen on the ACCT in that they progressively tighten up the chain with no going back till you physically reset it. My view is that they could put extra tension on the guides as the chain expands when hot an maybe getting a click of adjusment, then as the chain cools and shrinks, it'd tighten down on the guides as the tensioner will hold its new position. Just my personal view, but then I'm looking at it with a view of mechanical sympathy.

I've gotten a bit done this week with all the wiring now done and a dummy run done using the sensor.
All's well in that department. Here's how it went..........
(https://xs1100.com.au/forum/proxy.php?request=http%3A%2F%2Fi950.photobucket.com%2Falbums%2Fad349%2FEveready1100%2FXS11%2520oil%2520pics%2FScreenHunter_05Jun281202.jpg&hash=0104d9fdaf78d1531acc68e05b8f334a40014c6e)
^ Selected a suitable site for the relay. I then sourced a switched & fused power feed wire for the infeeds for the relay ( terminals 30 & 86 in the relay packet photo above). I just joined the two together as there's no real load on the circuits at all. The relay's coil ground wire (#85) went to the sensor and the power output (#87) went to the reserve light unit's old connector (Light green wire, centre bottom of the 6 pin plug). I don't know if it would work with the reserve lighting unit in place just by splicing it into the wire but that'd be worth trying.

^ Relay in its nearly completed state. Just have to put a heatshrink sheath on that top terminal to avoid any shorting out possibility.
Now, I'm just setting myself to pull the exhausts (again) and swap sumps over the weekend.
I will get out the measuring spoons and check everything with both sumps side by side on the floor.
Stay tuned!

love your work 8) :)

Threw the tank & seat back on in preparation of pulling the pipes & sump tomorrow. Ran the sensor wire to an underseat earth until that gets done. While checking that all my other wiring was still intact, I noticed that due to the relay taking a moment to energise when the ignition is turned on, you get a momentary flash of the warning light which shows that the bulb is working.
Hey, isn't that a self test??
Unexpected bonus!!
-
Didn't get as much done today as I would've liked due to domestic duties, but I'm ready to fit up the sump tomorrow. Here's what happened today......
(https://xs1100.com.au/forum/proxy.php?request=http%3A%2F%2Fi950.photobucket.com%2Falbums%2Fad349%2FEveready1100%2FXS11%2520oil%2520pics%2FScreenHunter_01Jun302014.jpg&hash=8aa4ddd73ce5247767cbc089e08e3237bb57791c)
^ loosened off the flange bolts and removed the rear exhaust mounts and let the system hang down just enough to be able to get to all the sump bolts. Didn't want to go through the dramas of trying to totally refit the whole system on my own again. Since the last effort, Neriel is calling the garage "the Chamber of Obcenities"

^ Then drained it of its lifeblood. I wasn't even going to drop off the filter but it looked like it might hang up on the front of the sump so off it came too.
(https://xs1100.com.au/forum/proxy.php?request=http%3A%2F%2Fi950.photobucket.com%2Falbums%2Fad349%2FEveready1100%2FXS11%2520oil%2520pics%2FScreenHunter_03Jun302014.jpg&hash=a6ba4dc86a21c268805f24cd4e245e4cc9aa6214)
^ was expecting anything after the reports from Rhodie and Jonesey about bits laying in the bottom of the sump. I was quite relieved that after over 280,000 klms under my butt, all it had to show for it was 2 small pieces of gasket material and a couple of small metal bits, mayve off the 2nd gear dogs as I have some issues there.

^ Gave it a good wash and then sat the old and the new down side by side to compare bits. Notice the small windage tray on the old one that sits where the sensor sits in the XJ sump.

^ The screen after cleaning.
I jinned around between motogp races cleaning off the last of the old gasket and am set to fit the new sump first thing AM. Will fill till the sensor triggers, then measure how much I have put in, which should give a good idea where it will go off if I start to lose oil.
Will keep you all posted.
-
Got into the bike nice 'n early this morning. Had a bit of a delay due to a stubborn piece of the old gasket stuck to the cases just behind the oil filter bowl mount and had a dickens of a time trying to get in a position to scrape it off. Next time, I'm gonna build me a work platform like Jonesey's so I can comfortably get under the bike and work on its nether regions without any contortions required.
Bolted the sump in place, then primed the filter housing and up it went too. The exhausts which had caused so much drama the last time simply swung back up into position and I slipped the muffler bolts through the holes in the mounts. Went up front and did the flange nuts then tightened the muffler mounts up. Took about ten minutes compared to the 3 hours for the last effort.
Then came the interesting bit. I turned on the ignition to watch the lights as I started to fill the sump. Surprised me somewhat when the light blinked off with around 2 litres in there. The funnel still had oil running through it so I couldn't get an exact measurement. OK, that works then, I thought, so continued on till the window showed the full level.
Pulled the plug leads and wound the motor over till the oil pressure light went out, then checked the window and topped it up to the full mark on the window.
So that's it. Took the bike for a hop over to Geoffs place to show him my new additions & had a wee conference on the pros and cons of the device. Frankly, I can see no cons in the modification other than the slight amount of power consumed by the relay coil and the bit of mucking about with the wiring to set it up, By the way, I haven't touched the bikes' main harness with this mod. I just modified an add on bit that could be reverted back to stock if required.
This might seem like a lot of trouble to basically idiotproof the bike ( We're all keeping a closer eye on the oil level window since the rally anyway) but I just wanted to see if it could be done...........................................................and it can!
Errol
Oh, I'll take a final pic of the dash when my super bright red LED comes in just to finish off.
-
On the subject of where the light shows level remaining....i guess they can t go too low with the setting as it would come on and off cornering the bike.
Were you expecting it to come on later than 2 litres as you filled it ?
-
I just thought that it would take a bit more than that from the measurements I took before assembling the beast. You're right Jeff. You probably would get false readings if it was set too high.
Actually, I did forget one thing in my other wrap up post.
The pro's of fitting one.
In the event of a holed crankcase or the sump plug falling out, this will give you a bit of warning prior to the oil pump starving and destroying the main bearing etc, so it could in fact be an engine saver.
BTW, How's your sump doing?
-
Sitting nicely on the shelf at the moment. :-[
As we are considering a ride here in Melbourne i m going to leave well enough alone until after the event.....if you know what i mean.
Two things i have down to do are......replace the valve seals.....as well as the sump/oil level switch.
Will probably do them both at the same time and still need to chase up a few parts in anticipation of both jobs.
Not to mention a few jobs around the house.......that will then allow me to go for a day ride and carry out the work on the bike........ :-X ;) ;)
-
hey Ev,,on the pic with the 2 sumps side by side,, there is a small {what looks like} brass piece protruding at the rear edge of one of them, what,s the go?
-
To quote an infamous (now deceased) QLD politician, "now don't you, you don't just, just you don't, don't you worry about that.........................................for now

Surely.... "All" ....Queensland politicians can t be dead!!!
Because they... 'All' ....sound confused to me!!!

Ok, the last bit - COST
I managed to get the install done a bit cheaper bu using some bits I had around the garage. For those without any access to wire, connectors etc, Here's what it would cost in total.
1/ The sump w/ sensor : Cost US $100 shipped to my door ( I have since been told I paid a lot for the shipping so probably could be had cheaper in the first place)
2/ Always open relay: $15 at local Autobarn store
3/ Warning light : $5.50 via Ebay - Click (http://www.ebay.com.au/itm/Red-Warning-Light-Lamp-12v-12-volt-Dash-Indicator-Classic-Kit-Car-Trike-Custom-/170709684581?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item27bf171165) If required
4/ 12v wire : a few bucks for some wiring from an auto wreckers will do the trick
So the total install could cost up to $125 but that's pretty cheap for absolute peace of mind

Hey Errol
That oil pump screen made me do a double take......thought I was looking at the pic I put up. Be interesting to see how many others are like that?
As for the bike platform........youll find it real easy to do the work your doing at the moment. combined with a stool on castors to work off it'll be a breeze........you'll be thinking up jobs that need to be done ;)
By the way....a very worthwhile job your doing too.
Jonesy.

Yes, Paul. I think that inspection of the screen should be put in the maintenance schedule after seeing what a couple of them have looked like. Not a regular thing but something that has to be looked at say, every 2 or 3 years. My motor seems to be mechanically quieter since before the clean, but that might just be me, or do you think it might be getting an extra bit of oil fed through it?
A platform is definitely on the short list now. It's one thing to reach in under the bike to undo bolts etc, but when it comes to doing something intricate, that's when you need the space to get right in there under it and still have room to move your arms around freely. I'm envisaging something portable so it doesn't clutter up the garage all the time, but anchorable so it can't move when being used but be in two sections - front wheel support and the back bit supporting the centrestand, with a removable centre section under the motor and maybe the rear section under the rear wheel to be able to be removed if need be.

I managed to get the light to trigger while riding to work this morning.
Henceforth, it shall be known as my I.C.I. (Imminent Crash Indicator)
Had a cane hauling semi pull out from a sideroad in the 100k zone on Goodwood road about 50 metres ahead of me. Hit the picks hard and just managed to get it pulled up before going into the nether regions of the bastards trailer. Nearly dropped it when the front locked slightly a few times during the event but managed to keep it upright, just. At some stage during the stopping process, I noticed that the light was on, but it went out again as soon as I'd stopped stopping. This was the first time it had shown up after a fair bit of test riding, up hill, down dale type stuff. Now I had an idea what type of force it took to set it off, I tried to exploit the symptom with a few drag style starts from the lights (that was fun) but couldn't get it to show up. I did manage to get it lit twice more under brakes, but that was using XSive braking force to light it up. Much, much harder than if you were only braking for a bend etc. Real crashstop type braking, so I don't think it's going to be an ongoing worry with it behaving like that.
I rechecked my oil level when I got home and it was about 1/8th" below the top mark, so that may also have contributed to things slightly as well.
