    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Help guys! I finally got my 78 550e running after a long winter of redoing the carbs, new to me coils, new points and condensors. And a lot of other little stuff. The bike runs like a song when it's warm, I'm tickled pink with how it performs except when it's cold. No matter how long i let it idle with the choke on it will never idle up. I can mess with the throttle and slowly get it to 2500 rpm and slowly take the choke off but it still runs falt until it gets to full operating temp. Help this is really embarrasing at work!

thanks

Neal,
I think you may have answered your post in your subject title.
These bikes are cold natured. Good size hunk of steel to warm up. Nothing to be embarrased about> Be happy it runs so well when it's warm.

You're one step ahead of me. I've still got to redo the carbs. Funny how we've had to replace the same things though.

I don't have much to add, but yeah, even when working properly these older ones take a while to warm up.

Satch
 
true, older bikes are a little more fickle cold than newer ones but this is the only one i've ever seen with the choke on for ten minutes and never idle up, and it still wants to try to die. I've found the 'sweet spot' and can kinda get out of the drive way in under ten minutes. i still love the onry little cuss.

What would happen if you installed larger idle jets?

you beat me to it!
adjusting the pilot jet a bit richer will help greatly with this problem.
the 550's came jetted way to lean stock and had a reputation of being very cold natured.
changing the pilot jets, or adjusting the pilot bleed screws is the fix.
 
You guys are too quick for me!

Yup. richer idle helped my 550L idle better cold.

Watch your idle setting though. Once it's warm it will idle fast (Around 3500). Luckily the idle on mine was easy to adjust from a riding position.
