Hello Everyone! This is my 1st day in the forum hence I'd like to thank you all in advance for your sharing of knowledge and experience. Pardon me if this issue has been discussed before, but I just couldn't find any info in the midst of topics related to the Concours.

My question is regarding a problem starting up the engine.

I have a Concours 1400 Year 2011 and I've been the only owner of it. I ride the bike only on weekends and yesterday was the 1st time I faced an issue which was a rather puzzling issue.

The usual temperature we ride in is 27-30 deg.Celcius, and yesterday I rode approx 100km up to a hill resort where the temperature is around 15-20 deg.Celcius with a little moist wind. I have similarly rode up to this resort over 10 times since i got the bike but never had any problems.

Yesterday I rode up with no symptoms whatsoever of any problem. After leaving the engine turned off for about an hour in the cooler weather, I wanted to ride back down but just couldn't get the engine started.
-There were no warning messages nor unusual indications on the console.
-The battery was fine and the engine cranked smoothly and normally
-The fuel pump was activated in a normal manner and there was no issue with the fuel supply.
-There were no known irregularities with the FOB battery, with all the fuses beneath the saddle, with the connecting pins of the ECU socket.
- I tried toggling the engine-cut switch while simultaneously depressing the start button (in case there was a switch malfunction)

The engine kept cranking but just wouldn't fire up.
I just couldn't figure out any other thing to check nor did I know what could the problem be. I called for a truck to transport my bike to the dealership.

It was an agonising 1.5 hour jouney down from the resort (I had to sit in the back of the truck with the bike). As soon as we got the bike off the truck, I just gave it one last shot and to the surprise of all of us there, the engine started up. I turned it off and retried, it started. I repeated this 5-6 times and there wasn't any problem anymore.

The technician at the dealership feels that the moisty cool air could have caused a weak connectivity at some physical electrical connection at any one of the sockets. I told him this wasn't my 1st time riding the bike there. I find it difficult to visualize what he said and cannot agree with his opinion.

Would you brothers happen to have faced a similar problem or could think of a more logical possibility of what the problem may be ?

Thank you.

Im thinking electrical. Something got lose on your ride up there for wouldn't start after being turned off. The ride down must have giggled something back causing it to start after the truck ride down. I would start by checking all fuel related connectors, than move on to wires and coils, ground, etc.
Something has got to be losing connection while riding.

Thank you Lou, I have inspected all the physical connectors that are visible beneath the seat. I may need to look for any other fuel or sparking related connectors that are hidden.
Do you think an electronic ECU diagnostic test would be able to pick up something now that the bike starts fine ?
BY the way Happy New Year !!

I'm not sure if what ever problem is causing this would through a code. But there is a test that would show any recent code. Give it a try.

non start problems starting

Hi ranjan,

I have had this problem on my current bike which i ride a zx1200r, over time regardless of age of bike the following can occur and it is nothing you can see visually without taking handle bar switches etc apart to component level, (yes the technicians opinion is plausible as moisture in any electrical contact can cause havoc as can different temperatures altitudes etc( speaking from experience and what i have read and learned.

bike will crank but will not start:- 1) you stated that you have toggled both the starter switch and the cut out switch at the same time this does some times get it started, however depends on how corroded the contacts are(if at all),

2) wires to the clutch lever cut out switch and switch faulty causes the same issues.

3) if the bike is in gear the gear selector switch faulty, and the side stand switch faulty, check all the above, i have stripped all my switches(the ones that i could with out having to replace the switch if it is a sealed unit) ive stripped them down to component level found the brass contacts corroded and pitted cleaned with emery paper so they are flat high spots taken off rebuilt starts first time every time.

4) the ignition keys on new model bikes carry a transponder chip in them that sync to the ecu (anti theft device) if the key is faulty or the transponder ring is faulty (intermittent this will give the same effects.

5) break in either wire to transponder ring (happened on yamaha r1) wires to taught in wiring loom when turning steering left to right caused an intermittent break in the wires making the bike unable to start then with some swearing and cursing it would start.

these are some of the main issues that stop your bike from running dont forget to check teh usual air/fuel spark etc though

kind regards

mike.

Thanks very much, Mike

Appreciate the effort and thought put in your reply.

I emulated the same ride up to the resort (with some backup this time) but did not face any similar problem.

components the key fob battery replaced and the fuel pump sensor checked. Haven't got to the control switches, gear/stand/clutch switch. In fact I'm pretty sure that if it were any of these componen then the engine wouldn't crank at all.

I'll updated you all in case I discover the actual cause of the failure.

Thank you and enjoy your rides.
