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.
Is this on a motorcycle? Really, just a stock airbox and a pipe the jetting required won't be too far from stock, maybe a size or two bigger mains, maybe a slightly different clip position. But what you need to do is run it, go through the plug chops and get it right for yourself.

No kits readily available for the 79. Stage one kits are for the cv series!

I was wondering if anyone has suggestions as to what size main and pilot jets I should acquire to have on hand for messing around with.

I think that the generally accepted position is to go up 5 or 6 sizes on the main and raise the needle (lower the clip) one notch.
Screw settings will be somewhere between 3/4 and 1 for the fuel, 1.5 to 2 for air.
Remember that these are only guesses for starting points, read your plugs to see what your engine wants.

And where is a good place to get jets?

You're right. I saw the "K&N" and didn't notice that it's an insert in the stock box. 
Oh, well, back to the guessing game. Probably 2 or 3 sizes on the jets, personally, I would probably do 3. My son's 850 has a pipe and stock airbox (with K&N insert) and has mains two sizes larger, and it's doing well.
