Low speed off.

[KeithO]

HI there.

I have a 2013 Trophy SE, which i purchased new in 2013. I currently have 81,000km on the bike.

Just recently i had a low speed fall, pulling out of a gravel parking lot up hill turning right. The gravel at the top of the incline was deep, so i blame the fall on the front wheel washing out. This off through my wife and i into a deep ditch, fortunately it was grass and no harm was done to us, just scratches to the paint work.

Fast forward one week. Same thing happens again in a coffee shop parking lot, no gravel, only this time, my wife breaks her arm and i suffer tissue damage to my right side. I have been riding for 40 odd years and this has never happened. I blamed myself for both incidents.

Then i started to do a little research to see if the bike, or engine management systems where at fault. I looked into the the throttle position sensor TPS, to see if this may have caused this to happen.


Just recently, when i start the bike it revs high for about 10 seconds before it settles down, i have also noticed on acceleration from a stop, that it skips, misses, just briefly, then carries on as normal. It does, (just recently) this every time i set off from a stop. So I am thinking that the bike could have missed during the slow manoeuvres causing a lack of power to the rear wheel, therefore causing an off.


Being in my sixties now I am starting to question my abilities with this heavy bike, or could it be an issue with the bike. Any kind of help would be appreciated.


Cheers, Keith.

Keith I am sorry to hear this and wish your wife a speedy recovery.

I am new to the TTSE, having just had my '13 since July 3rd. That said, my bike does rev a little high for the first ten seconds or so around 1600 RPM before settling down to right around 1000. In 3000 km I have not yet felt any power loss through the range though.

I'll follow this hoping your issue gets resolved.

Good luck,

Ed.

Sorry to hear of these incidents Keith, and hope you both make speedy recoveries. 

It is quite normal for the engine to run fast when started from cold,
and then settle down to the usual tickover speed as it warms up.

There have been reports from a couple of Members who had a probem with the Gearbox,
where it would jump out of gear momentarily during accelleration, but in 2nd Gear, not 1st.

One thing you could try is to carry out the "Engine Adaption" process,
which can help things run smoother by "Adapting" ( Calibrating ) the ....

Closed throttle position reference status
Twist grip adaptation
Oxygen sensor adaptation status ( off idle )
Oxygen sensor adaptation range ( off idle )
Oxygen sensor adaptation status ( idle )
Oxygen sensor adaptation range ( idle )

To run the process :

Start the engine from cold WITHOUT touching the throttle.
Don't touch the Throttle throughout the process.
Allow the engine to warm up until the Cooling Fans kick in.
Allow the engine to run for a further 12 minutes
Switch the Ignition OFF

Cheers

I also have a '13, just passed 90,000 miles.
There were several recalls on the early model, and many firmware upgrades.  ECU, centerstand, fuel tank, radio killing the battery, etc.

The ECU, reason was the original could be compromised by radio frequencies as I recall.

After I had this done, my throttle went from 'snappy and instantaneous' to 'mushy and soft'.  The next day, I dumped the bike turning around on a badly off-camber surface, and part of the blame goes to the 'mushy throttle' which I was not used to yet.  Half way through the engine died/I killed the engine, and, being as it was too far to the ground for my short legs, down we went.

I complained to Triumph, had it inspected at a nearby dealer, to no avail.

But .. the next firmware upgrade that came around ... The throttle was back to normal and has been since.

So I'd suggest you bring it to a dealer and make sure all of the recalls are taken care of and make sure they upgrade to the latest firmware version.  Not sure what that is however.
How to check the radio firmware version is detailed in this forum; you might find your dealer is clueless on that one.  https://www.triumph-trophy.com/index.php/topic,1887.msg91317.html#msg91317

I just turned 70, and I hear you about the weight and top-heavy-ness..

Thanks for your concern< coconut, and replying to my post.
 I performed the process as you described. just a little gun shy at the moment. I will take her out for a boot, the bike, tomorrow.

[KeithO]

Thank you all for your concern.

I performed the test as posted by coconut. will give her a run tomorrow.

Radio update is good.

I have had the bike since 2013 and have had all the recalls done ans all the firmware upodates. Since having all the work done this bike has been flawless, i have had down the Eastern sea board, mid west all over Ontario, and it has never let me down. It was blow to my confidence when this happened. no worries though ill be back in the saddle soon, as for my wife, well that remains to be seen.

thanks again.

Keith.

Hi Keith,
Something you might look into:  Around 45,000 miles, my 2013 started running a bit rough at idle, and fuel economy dropped quickly from averaging 43mpg to 38mpg to 32mpg, all in the matter of a few tankfuls.  It stalled a few times at red lights as well, then later I would need to throttle up in order to keep it running while stopped.  The problem ended up being an issue with the valves & valve seats.  A new head fixed the problem completely.  I'm thinking that if you're having the same issue, the bike could bog off-idle as you hit the throttle.  You would probably notice these issues, as they become quite obvious pretty quickly!  Hopefully it's an easier fix than that, though.

Keith, I too wish you both a speedy recovery. It is feasible that a lack of confidence following your first unfortunate drop contributed to you being overly cautious at the second event. I had a low speed drop about three years ago (I blamed the icy road surface!), and to this day I sometimes experience moments of tension during low speed sharp maneuvers. Now I just blame my age, and my pillion has to wait off the bike until I am in a more assured position for take-off 
Whatever the cause, mechanical or cerebral, I hope you get it sorted soon, and start enjoying your bike again, with confidence....
