Starting troubles

I recently purchased my first BMW ('99 R1100S) but one thing that's been bugging me is cold starts. I always need to give it a little gas when I start it up in the morning. I called the local dealer, and he said its normal for older BMWs to be a bit cold blooded.

Is he right? Or should I adjust my idle so it's getting enough gas to start up on its own?

Usual suspects:

Bad gas.
Tune up.

You can use the choke for faster warm-ups.

You can clean the starter.

You can replace spark plugs.
You can replace ignition wires.
You can check the battery voltage.

the choke mechanism on the bars is prone to breaking,
but it is not a choke it is just a throttle opening device,
so it opens the throttle while it is cold, should be warm in a minute or two in the summer.
the newer r1200xx engines have a automatic system to do this.
but check that the idle balance and throttle bodies are synced.
and plugs are good etc, the alternate plugs available also help cold starting

As a newish owner of an r11s, I'm probably not the best source of wisdom, but I can tell you my bike is in pretty good knick (25k, fresh plugs, fuel pump/filter, oil/filter, battery, always 93 octane w/ supplemental ethanol treatment, TB sync, valves adjusted all within the past month) and it behaves much the same. Always needs choke on cold start and even then seems to like a bit of throttle input on cold starts. Fires right up and idles/runs great, but cold starts seem to take more effort than I'd think than new. Warm starts are different and requires no choke or throttle input. I don't sweat it.
