Default Cold start issue, need help please

Is it normal for my 1992 Cbr 600 to have a hard time starting around 30 degrees f and lower? I’ve started it at approximately 10 degrees before and it starts up but I hold the starter for quite a bit. Usually I’ll have to hold it up to 5 seconds before the bike finally starts up. When it’s running everything is fine but I figure the starter is starting to wear. Let me know what you guys think! And if you need any further info just ask and I should be able to answer in a few hours! Thanks!

At around 32F, you should need full choke, but the bike should start quickly. 1-2 seconds.

My questions would be:
1. Are you using full choke?
2. Is your choke working correctly and adjusted? There is one on each carb, they all need to move together.
3. When was the last time the bike ran? The longer it sits, it may take a bit longer to start.
4. Why are you trying to start the bike at 10F? Where do you think your going?

I lol'd.

(I'll admit that I fire up the F2 in all kinds of weather just to get some new fuel moving through the carbs, but as far as riding, anything under about 50F and it's a 'nope')

1. Full choke everytime
2. Not too sure I haven’t had the bike long and was planning to clean the carbs before spring but it’s been freezing where I live.
3. start it once a week 5-10 min and if warm enough with no snow I’ll take it around a few blocks.
4. It’s winter, don’t want to let it sit too long.

1. good
2. dirty carbs can cause hard starting. Clean the carbs, clean carbs are happy carbs. Adjust the choke and check for wear on the choke pistons.
3&4. I see where you going with this now. So lets take a few minutes to talk about winter storage.

Your bike is not alive. You do not need to circulate the oil or fuel. You do not need to start it to keep it fresh.
Starting your bike once a week is an urban myth that just won't die.
It causes wear on the starter, the battery, the charging system. Wear on the cylinder walls and rings.
And not getting it up to FULL temp can cause condensation and rust in place you don't want to know about.
It's a hunk of metal and plastic, it's winter, leave it alone. You're doing more harm than good by starting it.

I've had my F2 24 years now. It's got a crap ton of miles on it. It's always starts perfect every spring.
Here's what you should do:
1. Change the oil. You want to store it with clean oil.
2. Run the bike once with fuel stabilizer in the tank.
3. Drain the float bowls. Turn petcock off.
4. Put it on a battery tender. (or take the battery out if bike is outside)
5. Throw a blanket over it and forget you own a bike for the next 5-6 months.

Damn, guess I found a soapbox this morning.

Thanks a lot! You pretty much answered all the questions I had. I’ll let it sit the rest of winter and hopefully I’ll have the time to clean the carburetor. You were very helpful, ride safe!
