There are 2 sides you can open. You want to open the side that the fuel lines go into and out of if you only want to do the screens. Like I previously posted you'd probably want to clean the whole thing...

The carb manual link is: http://www.mikuni.com/pdf/sbn_manual.pdf
In 97 BRP came out with a new hull and made the new "XP." The X-4 was then downgraded to a SPX, although the same as the 96, just white top hull and minor engine changes. The 97 XP was the dog of all XP's, because it was intended for the 951 engine, which was still in development and hadn't reached production yet. So they backpeddled and did not release it. Remember the problems with the 97.5 GSXL 951? Now you know why. From 97-2003 the XP was the hyperbolic hull.

will it be possible to take the carbs apart to clean the filter and put them back together without new gaskets?

The base gaskets might come off OK, but they also might come apart. Make sure the dealer has some in case. Also, personnally I replace the filters instead of going through the hassle of trying to clean them.
If you need fuel line, the cheapest I have found it in Canada is TSC.
While you are tearing into things, you should check the alignment on your fuel pump and move the ground wire from the starter up to the rear of the block.
Also, if you have the carbs off and want some extra power, JayZ or Robert can give you some rejetting tips using the stock airbox that will make a big difference in power. Caljet should have the jets and N/S you require.
Feel free to join JayZ and I if you want to ride with a couple of other 1996 XP's. We also have lots of spare parts in case you are ever in a bind.
