Trumph sprint rs idling hi in neutral

Can you give us a bit more details about the bike? What year is it, for example? I'm assuming it's the one in your avatar so it will be fuel-injected I think.

 

I have the same motor in my Tiger 955i and had an idle problem - sometimes it was high other times it wouldn't idle at all.

There is a device called IACV (Idle air control Valve) which controls idling; this is connected to the throttle bodies using vacuum pipes. This valve can get dirty and sticky causing erratic idle, plus the vacuum pipes can perish losing the vacuum. This could be at the bottom of your idle problem.

 

It's not something I've done, so I can't speak from personal experience but I believe it is possible to re-set the idle using a free-to-download program called TuneECU (google search) and an OBD connecting cable (about £15).

With this set-up you can do loads of checks/changes to the way the bike works, including re-mapping the ECU.

 

I have an electronic copy of the service manual I could send you, if I had your e-mail address?

 

Sorry mate, just tried to send you the manual but my e-mail server says the file is too big and din't allow it to be sent

PS RE the clutch cable, I think the guy said you need to tighten the cable a bit, to reduce the free play.
