I have made a simple airbox modification för the Steamer. It involves cutting the left "leg" of the airbox so it can be taken out to the right side without removal of the tank or carbs. See attached pdf.

Cool solution.
Not quite clear to me how the cut part stays attached to the foam and retains its integrity from the mechanical point of view.?

Nice work. More than one way to skin a cat, they say.

That was my thought as well.

How does it stay there?  There's nothing to hold it in place?

Just a thought, but seeing as how one of the snorkels is capped on a Tiger anyway, couldn't you just cut that bit off and glue a blanking plate over the hole, then you could bin the chamber on the side of the battery altogether.

Do you reckon that would work, or does the chamber have some other magical function?

I'm not sure, but on an old Yamaha I had, the volume of the chamber was decisive. Any changes and it ran like an old lady. I am interested to see how that works out with this mod.

that extra space on the right side helps feed #3 with enough air even with the cap on it .
IIRC it starves for air on #3 without the extra volume.

I can see that many of you think this is not holding up, but the foam is glued to the short piece and then this piece is pressed by the help of the retainer screws (I actually only use the screw closest to the engine because u need to remove the battery to loosen the second screw). The pressure is enough to keep it in place. Surely its possible ot reinforce the connection with silver-tape or some bracket.
