Alloy finned 'flange fitting' spacer of the type often fitted to sports or racing motorcycles (and Cafe racers) in the 1950's-1960's. Fits those types of Amal carburettors with 2.0" stud distance flanges (i.e. TT/RN carbs, Monoblock, Concentric etc).
These are CNC machined and look nice quality. They are 1" in depth, which makes them very similar in dimensions to the spacer that was sometimes fitted to SOHC Norton's by owners who were fitting a 'short neck' Amal TT or RN carb to their Norton, to replace the original fitment 'Long Neck' TT or RN carb, which are now much rarer to find.
This type is 26mm Bore - but is useful if you wish to open it out further to fit a particular size of Amal TT or other similar type carb.
We also offer a similar spacer in 32mm bore size (Item 0945C) and can obtain some other sizes by special order - email us at sales@racingvincent.co.uk
Note: the accompanyning photographs show one of these spacers held up against an original Monoblock carburettor and also a genuine Norton 'Long Neck' type Amal RN racing carb - as these were what I had available at the time for the photo session. However, if you already have a 'Long Neck' type TT or RN carb fitted - you should not require a spacer.
