Irratick tick over.

[TT Ashford]

Bike has recently developed an annoying habit of either cutting out on a closed throttle or ideling at anything up to 3000rpm, runs perfectly other than that, dealership in Melle, France had a quick look but couldn't find anything obvious. Bike is now at LPC in Ashford being looked at in detail, awaiting there call. Anyone had similar problems?

The problem with diagnosis on this bike is the fact that it could be one of so many things...!

Initial thoughts are an air leak on the inlet side of fuel system but that's on a conventional bike - might also be a TPS unit fault but either way your Trumpet man should get it sorted quick enough once plugged in. 


I had an Erotic tick over once but never found the cause...

Hi TTAshford,

I agree with Rocket Steve - especially if your Trophy has recently been serviced.

Other Members have had Dealers that have not seated the throttle bodies correctly
( apparently this is a bit "fiddly" to do ) which can cause an air leak and rough idling.

Something that can often help, and several Members have reported
curing similar problems this way, is to carry out a manual "Engine Adaption" procedure.
( Search "Engine Adaption" for more information on this ).

It's simple to carry out this procedure yourself :

• Ensure the engine is COLD
• WITHOUT TOUCHING THE THROTTLE, Start the engine
  and allow it to warm up until the Cooling Fan comes on.
• Leave the engine to idle for a further 12 minutes.

After doing this if your Cruise Control warning light is ON at Ignition On,
but cruise control will not engage, then see here :
False Warnings for further information and how to reset it.

Cheers

yeah I've had that ... twice.... its one of the issues that I'm hoping will be cured at the next service.. last time they said it was the throttle bodies and the throttle sensor position....

Pain the arse!!

Finally able to update, cylinder head has been removed and found one exhaust valve in each cylinder has significant damage around the edge's. have tried to upload pictures but can't for some reason. very unimpressed with a bike that was first registered in 2013 and only has approx. 44,000 miles on it. Triumph aware and awaiting their response.....

Just wondering, have you any previous service records etc regarding inspection/adjustment of the valves??

[TT Ashford]

At great expense it has a full service history carried out at the same dealer, Laguna Ashford, who are always helpful and through, if a little expensive.

[earthman]

Hmm, so my assumption is that the actual metal of the valves wasn't up to scratch then??
