I bought this machine for $1500 and took it to the Honda shop for a thorough service.
After replacing the brake callipers, fork seals, rear disk, TIMING BELT, radiator header and fan motor as well as plugs air cleaner etc they now inform me that that the pistons and rings need doing.
So I shall be cutting my losses and selling the bike with 6 months rego for whatever I can get.
So far the workshop bill is at $2500 approx.
If I can get that much for it I will be only $1500 out of pocket.

G'day Cesspool. :think1 juST a queSTion, How many K's on the clock , its a 98 yr?
mines a 98 ex police with 167,000k's I'm juST thinking about the piSTons and rings they say need doing..

even though mines a 99 and at 182,000k I still haven't needed to add oil between the oil change period.

Alan :thumbs STranger also hasn't used any oil between services, that's why I was wondering about the mech saying piston and rings need doing.
:think1 Maybe the mech is hoping to pay off his mortgage :well :OldMan

Their compression test was like 70psi dry on the 2 RHS cylinders, 95psi wet. The 2 LHS cylinders are up at over 140psi wet.
What are you guys suggesting???

Looking at the list of work done "????", I think you may have been had. For a start, the compression check should have been done first (after pulling the plugs ), not after replacing everything.
I'm sure a member near you can double check the compression test, I have never heard of an ST that needed rings..
My ST has 152000 on it , and only had tp replace the calipers cos the pad retaining pin was seized. The rear disc needing replacement perhaps.

Gday Brock here is some lowlights of the day's play:
Marc from Honda shop:
"We have completed 90% of the work needed to the bike, and the tech was on the final stages of completing the job.
During the last few stages, the tech did a tuning process on the bike. This is to sync the carby’s, tune the motor, and make everything run smoothly and in unison.
Unfortunately, during the tuning process, the tech noticed that one cylinder was dropping in and out. Once the bike was up to running temperature, the 2 left hand cylinders were not firing at idle.
Obviously this was an unexpected issue, so the tech looked into the cause of this, and a compression test revealed low compression on both left hand cylinders, which would be due to damaged internals.
What this means, in short form, is that 2 cylinders are not functioning correctly due to worn pistons and rings, and potential other internal damage.
The unfortunate thing in this case, is that the bike was dropped off to us with no mention of any engine issues, and supposedly running fine, and a list of other jobs to carry out on the bike (a service, but no major engine work).
Therefore we set to work on all the other requested jobs. It was only at the final stages of the service tha..."
Me:
"When I dropped the bike off I did indeed mention this problem, namely, that two cylinders were dropping out in combination with the brakes being automatically applied at the same time.
I mentioned that this combination of symptoms suggested to me that the ECU was playing up.
I also told the guys that I interrogated the ECU for fault codes and found only a low voltage code which I cleared. This bike sat with a flat battery for years I have been told.
This issue is intermittent and therefore very difficult for me to diagnose. My strategy would be to swap out the ECU and see if the problem goes away. I will try to get one from motorcycle masters.
A compression test should confirm healthy cyls and rings. I did one and all seemed OK some months back but I only had a El cheapo gauge."

An elcheapo gaugemay not be accurate, but it will give a good indication of bad cylinders.
The valve clearance on the left bank may be out, causing them not to seat fully. That will also give low compression.
I dont even know how to interrogate the ECU on the 1100, I dont recall a port for that..
Is your bike an ABS model??

From the thread title I would say it was.
Nothing on there to test it that I know off unless you pull the connection off and connect the tester to it. Not only controls the spark etc. but takes info from the ABS sensors for the traction control system

I had similar on my old gs850, and it was burnt valves (prev owner never checked them). The problem becomes less obvious once you are riding, and was worst at idle.

Yep it's got ABS/TCS/LBS.
The ECU gives out fault codes by flashing the dash lights when you turn on the key while holding certain buttons depressed.

That's the ABS sensor codes which has nothing to do with the ignition and from the ABS module which is item 14 here http://www.st-1100.com/st1100-parts-fiche-fairing-stay-st1100aw.html (http://www.st-1100.com/st1100-parts-fiche-fairing-stay-st1100aw.html)
The Spark and TCS unit or item 1 is located in front of the gauges and behind the headlight.

Thanks Alan I have examined that unit and about all I can do is note that there is no evidence of burning on the PCB under all that encapsulant.
I like Brock's suggestion of getting someone on Perth to check the veracity of the compression test but I reckon they will not allow anyone in their workshop on ohs&e grounds etc.
Especially since I sent them this:
"I expected the first priority was to investigate the misfiring and brake problem. This is what I asked you guys to do first.
The general opinion of the ST owner's club is that a competent technician would check the compression immediately following the removal of the plugs.
Therefore it appears we are in dispute, and I will need to refer the matter to consumer affairs."

So this machine now has brand new Bridgestone batlax tyres, new fork seals, new rear brake disk, new timing belt, new pads, and is registered til march 2017.
Unfortunately the engine compression is poor as the Honda shop correctly diagnosed. The bike starts and runs smoothly over 3000rpm and has reasonably good acceleration and top end
Most unfortunately it has met with an accident while parked in the carport. The wind blew a stack of doors on top of it damaging the top box scratching the air cleaner cover and destroying the rh mirror. Also I have disposed of the sidecar I was intending to fit.
So the bike is for sale. I'm asking $3k, ONO.

Give me a ring 0418937173, I have a spare 1100 motor if you are interested, it would be interesting to find out history on this bike, sounds to me as though it has been cooked at some stage of it's life
