1980 Kz440 ignition system

So to use those individual pod type air filters instead of the stock airbox, I would need to rejet the carbs?

You can boil some water and soak the boots in the hot water. That'll make the boots more easier to put on

Yes , get the jet kit .

440 airboxes are not hard to find on ebay or bike yards. 

I was messing around with the bike today, and spraying starting fluid in the lower intake box (I don’t have the upper box w filter element). I probably sprayed too much but while cranking, there was a pretty big fireball from the airbox. What would cause this kind of backfire?

Either getting to the spark plug.

Is this something that I should look into more?  Does this mean the spark timing is off?
