Hard to cold-start indicates a lean pilot mixture.

Few things might help:
1. Bump the pilot jets to 42
2. Check your entire intake system for leaks. Cracked rubbers, degraded o-rings and degraded vaccuum caps are likely culprits.
3. Lean out your idle mixture screws to around 3 turns.
4. Check your spark plugs and replace if necessary (takes 20 minutes).

When's the last time you had your valves checked?

Not great gas mileage and it smells like it runs rich to me. I'm a complete newbie so I could be completely wrong. I haven't had anything tested to confirm that suspicion.

Check out the easiest and most obvious things before tampering with mixture screws and jets.
1/ Air filter.
2/ Spark plugs.
3/ Vacuum caps. They're the little black rubber bungs, (2 on top of each carb manifold) they're notorious for perishing.

When you try to start your bike, DON'T touch the throttle until it's running.

Yes they're slow to warm up and don't reach full temp for 15 minutes so you might need to goose the throttle a little at junctions and in traffic until it ticks over on its own.

Make sure the two wires on the bottom each carb are intact and connected. They're the cold weather carb heaters that come on automatically under a certain temperature.

+1, yes mine starts first go hot or cold, do same as above.

I will try it. What will this do?

If you twist the throttle whilst pressing the starter button the carbs will flood with fuel and can soak the spark plugs = bad or no start.

It prevents flooding...

Hmmmm. I don't know. I'll have to check the records that came with the bike from the previous owner. I've only owned this bike for 6 weeks or so. It has been well maintained with all the records included. I feel like I may need to take it to the local dealer and have them do a once over.
