this item does actually come with the gasket kits supplied separately- its surprising how many carbs are supplied WITHOUT it

I would recommend jetting and sliding for GP200. You may have to play around with the main jet- either 118;123 or possibly 125.

You will also need the 22mm carb inlet manifold and carb bellows etc.

I run a 22mm Jetex with a 175 Stage 4 kit and an old DJ expansion exhaust. I'd definitely get a 150 slide (the one with the scoop out the back), a -2 atomiser (I think they come with a 6 or something anonymous. Get a 2) and a 122 main jet but it's a bit lean WOT so I've just got hold of 125 to try.

The slide is important, they come with a 200 slide as standard which is far too rich for a small block and you'll never get it jetted properly as it will be too rich at low revs and too lean at high revs.
That's my experience with the damn things - I'm glad there's not much else to change.
