Oh the joys of pre-beam framed bikes.... Carbs will be much easier to remove and refit without the standard airbox, but it'll take a lot of fettling to get them running properly with K&Ns or whatever you end up using, and they'll be noisy as well. Before you spend time balancing the carbs you may as well check and adjust all the valve clearances and balance the carbs when you've done that. It's normally a piece of cake on Kawasakis with CV carbs, attach the gauge hoses to the appropriate balance take-offs (hopefully they're on the top of the carbs on this one, not underneath on the inlet manifold like they can be...) and balance carbs 1&2 together by the small adjuster screw between them, then carbs 3&4 likewise, then the pairs of carbs together by the screw between #s 2&3 - dead easy [smiley=thumbsup.gif] - Don't lose the vacuum take-off caps!
You mentioned a fuel pump - I wasn't aware that these had a fuel pump as they gravity-feed to the carbs from the tank don't they? (I don't think this model is injected as you've been talking about carbs all through so far...)
