Mine doesn't get over 1,500 either. Although at the end of a spirited drive the other day, the idle was a little uneven, going from around 750 where it sits when warm up to 1,000 in short bursts. That's clearly a different thing, and I've yet to see if it does it again.

Something similar here that only seems to manifest itself when I have been manouvering in the drive when putting it away - rises to 1,500ish and then dies back down to normal after 10 or 20 seconds...

Twink, I think anything up to 2k can be considered "acceptable" bearing in mind we are talking about an engine with over 100bhp per litre.
The rising revs I intermittantly experience with my MC goes up to 4k! This of course is not acceptable...Out: 99 S50 Titan Silver V876 KKO

Hey...
I had same problem in my old MC, small blip on the pedal would sort it out.
Also had same issue on my 993 Porsche, turned out to be the Idel Stability Valve. Simple case of removing, spraying with cleaner (ton of carbon crap comes out). Problem went away after the clean although is a common issue with the 993's.

Even if it doesn't look overly tight, maybe slacken it as an experiment to see what happens.Out: 99 S50 Titan Silver V876 KKO

The only other small chance is that one of the throttle bodies isn't setup properly or is loose (worn ball joints on the levers etc allowing one throttle to open on its own a little).

After owning my MC for 2 weeks I had the high rev problem this morning. When I start her normally from cold it goes to 1500rpm and then settles around 1000rpm after 20 seconds or so. This Morning it jumped to 3000rpm and contained to rise and I turned the engine off in panic and when I started it again it was fine.
If everyone could let me know how you get on that would fantastic :)
