Suzuki 2 Strokes

many thanks if you can. i got 2 of these with a job lot of t250 bits. they are obviously not t250 as they are off a single cylinder - but which one? they are very shallow - only 70mm deep and that 'D' shaped rubber might give someone a clue. i've looked all through the parts books on alpha sports, but to no avail. that's just supposing they are off a suzuki, as i'm only guessing. somebody somewhere might know
cheers, dd.
p.s. that doglegged rubber is 45mm i.d. so presume a fairly large carb.

Nope. Ask me one on nuclear physics.

Honda and Yamaha had twin cylinder bikes with separate air filters boxes with a connector passage between the two air filter boxes.

Per a quick eBay search, it looks a lot like this one from a Honda CB360: https://www.ebay.com/itm/350891440083

many thanks for that jab, that looks pretty damned close. i looked at the 2 airboxes i've got and they are handed, left and right. not worth a huge amount but hey ho
cheers, dd.
