Hi Jerry,

Thank you for replying.

Do any of your bikes have the pipework to divert some of the engine oil through some pipework to the carb float chambers? Presumably, to do something about carb icing?

On the RHS (sitting on the bike) oil cooler has a T-piece in it, with a tap which is presumably to turn this system off in warmer weather? Because of this, and the braided hose that goes from this tap to the float bowls, even if I unbolt the oil cooler this pipework prevents me moving the oil cooler down out of the way.

The pipework from this tap goes from the RH oil cooler feed pipe to the RH float bowl, then to the LH float bowl, and from there another pipe returns back to the side of the RH oil cooler connection.

I have (I think!) attached three photos of this tap & pipework. Do any of yours have this system?

Thank you, Brian.

Edit - uploading the photos failed, I'll try again on a separate posting.
