Bike takes a very long time to warm up

[kord_f]

This doesn't cause too much of a problem for me but I'm wondering if this is something that can be fixed.  From a cold start it takes my bike a good 4 or 5 minutes to get warmed up with full choke.  My brother is on a 99 bandit 600 (I'm on an 07 GS) and his warms up substantially quicker than mine, probably in about half the time.  What can I do to fix this?

What is the air temp when ya start the bike and it does this? When it is around 50 degrees or below, (parked outside at work all day or whatever) my GS takes I'd say between 3 and 5 minutes to warm up too. It's a '98... I always thought that was normal? I will say though that in my garage at home it is anywhere between 68 and 70 degrees and tends to warm up a little quicker than that (again after sitting all night or for a day or more, etc).

This is in about 60-65 degree weather after sitting overnight.

On a Bone Stock bike right out of the box you can go up one size on the pilots and the mains, that's what I did with my 07, Thankyou EPA

My 02 takes every bit of 5 minutes to warm up....and it's a lot happier after I have ridden it for another 10

Thank God for FI, now folks will never have to learn how to use a choke.  My stock 02 is ready to go about the time I hit the end of the driveway.

You're not stuck in the snow storm up north?

lol

Big snow was east of us. Besides I did my 30 years of winter riding.  Maybe next spring, maybe not.

Yep this x1000. I don't have to use choke for any longer than 2 min even in 30 degree weather because I've rejetted my bike. Between the EPA and California they tend to ruin everything good about everything.

If I was a current day Hipster it would be #ThankyouEPA

One step up on a Stock '07 would be #20 pilots and 132.5 mains

even after a rejet my bike takes about 5 minutes in this cold ass chicago weather...

And 3 times to start and run on both CYL! always fire up on 1 then is like "ohh wait I have two pistons"....Then again I still need to sync it after a carb rebuild..

How do you even ride it with the carbs out of sync?

[RichDesmond]

If it's taking 4-5 minutes to warm up enough to be happy it's likely that low speed circuits on the carbs are at least slightly gummed up. A carb cleaning will help. A #20 pilot and adjusting the air screws is a good idea too, if you've done that and and the bike isn't ready to ride almost instantly then a carb cleaning is in order there also.

the warm up is for getting the oil to a safe operating temperature... if your oil is up to temp, you should be able to to just go.

some people say putting a piece of cardboard over the oil cooler helps to warm up the bike for you northern folk.

sorry for the hi jack , but going up 1 jet size from stock...would that do it for a slip on or is further jetting needed ?
