High Idle w/ Choke

I'm new to vehicle ownership, so be gentle...

Every morning when I warm up my bike (06' GS500F) to head to work, I turn the choke on before I start. Bike fires up and idles around 1200-1400 as I would expect.

After a minute or two, all of a sudden the RPMs raise quickly (within a second or two) to about 3000. I can fiddle with the choke to get it back down to 1200, but there is a very thin line between staying at 3000 and dropping to the point the engine almost cuts out. It will usually do this again one more time at the new setting, after which I just turn the choke off.

Am I correct in thinking that 3000 is too high to be normal? This isn't a serious issue (I don't think), but it's made me curious. Other than the noise 3000 makes at 7AM pissing off my neighbours, it hasn't been a problem.

Any guesses on what could be causing this? If it helps I might put together a simple video showing what I mean.
 
Its cold and you now have to warm the poor little carbed beasty up

-Start full choke
-When the rpms start to go up drop it to half choke
-When you can have no choke and the bike doesn't die you are fully warmed up and ready to ride

Welcome to cold weather riding :)

If you want a more detailed answer I can give one, but in short its normal.
 
That's good news. I thought the carb needed some adjustments, but if it's just the cold that's even better.
 
Mine used to jump to 5500....so yeah, it's fine. I'd actually let it warm up around that high and it was still fine.
 
OP idk if I read it right but why are you riding with the choke and then doing some more fiddling.

In cold start you just choke to start.
Then cut it when your bike has warmed up.
Then ride away without any choke.

If you're riding with the choke on then your RPMs will definitely be high.
