Connecting pipe balance
Balance pipe connecting the two carburetor intakes on Amal Mk2 Concentric twin-carb setups.
This is the balance pipe that connects the two carburetor intakes on twin-carb Triumphs running Amal Mk2 Concentric carburetors. It ties the two intake tracts together so both cylinders draw evenly and idle settles down instead of hunting between the two carbs.

It shows up in the parts book under the Amal Mk2 Concentric carburetor figure, so it's specific to setups running that carb type rather than earlier Monobloc or Concentric Mk1 rigs. The catalog entry we have on this one is brief, so if you're not sure whether your carbs are Mk2 Concentrics, best to check before ordering.
A balance pipe like this is a simple part but an easy one to overlook when troubleshooting an uneven idle or one carb running rich or lean relative to the other - a cracked or loose fit here can throw off both sides.
