High tickover??? Help.

[blacktiger]

I need help. Yeah I know.....
When fully warmed up, my 955i has a high tickover which will drop back to 1100 after a while (several minutes) but when riding it stays at around 1500rpm. I've replaced the crank speed sensor and the rubber gasket around the IACV but it's still doing it.
Anyone had similar?

As its an efi, I cant help on the electronics side of the issue, but, have you checked the basics such as free unrestricted return of the butterflies, ie,not sticking or a spring binding somewhere.

Not yet. By posting this I was fishing for ideas before I strip it down.

Some of the regular Tiger owners will most likely see this tonight.

I haven't experienced this so I'm not sure if there is anything short of stripping it down to check it.

Not yet. With outside temperatures hovering around freezing I ain't doin' nothin' in my unheated garage.

 

[CarlS]

I can understand that! Do keep us posted on what you find, please.

Mate of mine has suggested this :-
Time to clean the inlet tubes then. The butterflies in the inlets get black deposits around the spindles and this builds up. So a complete clean required. Solvo and WD40 with a stuffed rag in the inlet usually sorts it out. No need to remove from bike. Adrian Pondlife gave me these tips years ago.

Many Thanks

just a thought check your vacum pipes for holes or cracks my 900i had a high tick over and thats what it was (sucking air ) ,
also mine ticks over around the 1100 mark but is spot on as soon as you turn the lights on .

To me 1100 IS spot on.
Thanks for the vacuum pipe tip.
