    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...

    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.

I'd like to remove the air box from my 78 GS550 and install four K&N pod filters. Will I need to make any adjustments to the carbs for air flow or should it be fine as is?

Yes, you will need to re-jet the carbs due to the increased air flow. There is a search feature in the upper right corner. Use it and type in jetting, re-jetting or some such thing.
I hope you don't hurt your eyes reading the 40 bijillion posts....:)
 
You have vm22 carbs so you won't be buying any dynojet kits. The CV carbs people say are a huge pain the rear but the VM carbs are much more friendly.

The only places I know of that you can buy the main jets for our vm22 is jetsrus and on ebay. If you do go this route please update because I would like to know how it goes for you. :)
 
Easy enough to dial the carbs in on a '78 - bigger mains, lift the needles and play with the fuel / air screws (no need for bigger pilot jets). Make sure that when you buy the pods you get the measurements correct - a lot of them foul the frame on the 550 (on nos 1 and 4) and won't fit.
