Any Japanese thumpers with the BST carb?

This low pressure also causes a low pressure inside the carburetor. Since the pressure is higher outside the engine and carburetor, air will rush inside the mikuni bst 33 and engine until the pressure is equalized.

The moving air going through the carburetor will pick up fuel and mix with the air. Inside a carburetor is a venturi, fig 1. The venturi is a restriction inside the carburetor that forces air to speed up to get through. A river that suddenly narrows can be used to illustrate what happens inside a carb.

The water in the river speeds up as it gets near the narrowed shores and will get faster if the river narrows even more. The same thing happens inside the carburetor. The air that is speeding up will cause atmospheric pressure to drop inside the carburetor. The faster the air moves, the lower the pressure inside the carburetor.

To minimize time taken apart waiting for parts, what should I have on hand? I was going to order new gaskets, should I have floats?

Those Mikuni carbs

Thanks, Ross Roy Gavin The alternative is to fit Keihin FCR33s instead, for even more performance but serious outlay. The FCR is a flatside with accelerator pump; you can snap open the throttle and the bike wants to mikuni bst 33 from underneath you.
