07 Ultra. Today I run up the shop to get a few odds & sods. When I fired her up it run as normal around 1300rpm and slowly came down to 9/950rpm. I went about 3mi to the shop and shut it down a 1/2hr later I came out straight it up (it fired strait a way) the idol was all over the place (Hunting) also popping back though the intake. I gave it some throttle only a little and it raced high, now I didn't shut it down thinking it wouldn't start again. I rode off with it still popping bake though the intake and hunting I got about 200yards and it cleared up. I got home and restarted it up it was fine normal.
Is this something that can happen now and then and not to be concerned about? or could it be a tel-tel sign of a pending fault that may occur?
Have you had it happen?

I have had that happen if I start the bike and before the idle goes down I take off.

I did move off 50ft then stopped and left it running while I geared up. But it's something not uncommon I do it every time I've gone out. I went out today I did the same thing and didn't have any problem she run and started up 5/6/ times when I stopped off 

Perhaps it was just a electronic glitch Thanks on the feed back. I know now it's something that dose happen

I was having similar problems on my '07 early last year - intermittent erratic idle; sometimes stubbornly high; sometimes drop down so low the motor would die.  Don't recall any popping however.  In the shop several times trying to diagnose and spent several $$$ to no avail.  Finally another shop started at basics (where you should always start in any case, lol) and found a small intake leak.  They replaced the intake gasket and thankfully the problem has not recurred.  Note that this problem arose immediately after I paid the dealer to change the inner cam bearings and lifters on the bike so I think this was the tech's fault.

Thanks ultrafxr,  the info. is helpful I had a intake leek once before one of the mounting bolts worked loose I replaced the gasket and also put a light film of heat resistant silicone on each side of the gasket so I hadn't given it a thought.  I check it by giving it a small concentrated spray of ether on the flange that will tell me if there is a leek if the rpm picks up. The fault hasn't reoccurred hopefully it was a one of.
 Going on a 600mi round trip on Saturday. I hope the old girl behaves her self
