intermittent faults

[Tally]

Mr Gee .
I have a question for you.
Are the battery cables firmly attached to the battery, especially the live (+)cable. I had a problem with an old car once and that was the cause, the cable no matter how tight you tightened it down it would work loose and cause the fault . The only other reason I can think of is you have a live wire shorting out somewhere on the frame. Good luck with your hunt for that elusive pimpernel

When the bike cuts out do the needles still sweep if you try to restart?
I had a similar problem with mine and it turned out to be a faulty battery, when I went to check the voltage of the battery, put my meter on the terminal and terminal was broken inside the battery I could physically move it with the probe...strange but kept working for most of the time.

Right, it's a K5, the model that had issues with the antenna.  If I recall correctly, Suzuki did a recall on that part for the K5 & you could take it to the dealer & they'd check if the recall had been done using the VIN. If not, they still perform the recall FOC now.

My suggestion is to find out if it's had the recall done or not.

I rung a dealer over here & quoted the reg to find out if the recall had been done on one a couple of years ago. So no need to even drop in if they aren't local.

Can the immobiliser be removed (after speaking to her nicely), perhaps threatening to remove some parts may help?

Also, the key tumbler does get a lot of crud in there, it can be removed from underneath the head stem, bit of a fiddle and I think you have to drill out two rivets that can be easily replaced with bolts or screws, this allows you to clean out the key tumbler.  alternatively to pulling it apart, spray some contact cleaner into the key slot (cover your tank and front mudguard with a towel), let it sit for a minute then blow it out with compressed air, may dislodge and remove some of the crud and clean the contact ring ? just a thought.

Antenna has to be there, to connect with immobiliser and immobiliser has to be there, to connect with ECU. 

Have tried cleaning out key barrel but might get my mate, to try stripping it down and reassembling.

The guy is a genius. He has tuned bikes for Mike Rutter (second place at the TT, after leading all the way until the last lap) and other racers too.

I bet Rutter never asked him to clean out a key barrel...it may stretch him!

Symptoms certainly point to immobiliser, especially been a known fault with K5 but no certainty 🤷.  Check out your recall, hopefully thats an option🤞🏻

The key barrel & ignition switch aren't too bad to strip & clean, just small fiddly parts.

Barrel - https://gsx1400owners.org/forum/index.php?topic=6266.0

Switch under the barrel - https://gsx1400owners.org/forum/index.php?topic=6268.0

I'm kinda suspecting a broken wire in the loom where it goes around the headstock though, seen it on some other older bikes.

Thanks for the link that will come in handy.

Does your model light up as soon as you turn the key ? My K5 EU one does, and I had an intermittent electrical issue. Turned out the starter button had a very minor oxidation on the contacts and I only saw it on the second go; was thinking only the start position would influence, but rest position was the problem.

Sorry, missed your post somehow.

Mine lights everything up and the clocks sweep but it is no longer registering the key. The lights on the antenna aren't flashing now and the code reader says check but you can't, because the engine needs to start before the fault registers.

Mate, did you check if recall had been done? Sounds like first action to me, if both keys ok, then receiver sounds faulty

Yes the recall was done just after, I first bought her early in 2006

Been running sweet for the last twenty years and still does when it runs.

I suspect the receiver too but how do check it out.

At £256 plus, can't afford to simply fit one and it not, be the fault.

Can understand, lot of bucks to just hope.When I was working used to get lots of cars with faulty key readers. They could be diagnosed thru OBD2, pity our bikes cant. Just been searching, cord available to convert our 6 pin to OBD2,never heard it mentioned before. Anyone used it?
