Tufnol spacer flange to fit between cylinder head and 'flange' type carburettors - i.e. Amal TT/RN, Monobloc and Concentric carbs.  This listing is for a 30mm bore spacer, 6mm wide.  

These 6mm thick tufnol type spacer flanges were a common fitment on many models fitted with Amal flange fitting carbs.  We keep two bore sizes in stock:

- 28mm bore - which equates to 1.102" in imperial size and very similar to the 1 3/32" (1.093") bore fitted to many Norton 350cc SOHC models (see Item listing 0844a for this)

- 30mm bore - which equates to 1.181" in imperial size and is somewhere between the 1 5/32" (1.156") bore and 1 3/16" (1.1875") large bore TT carbs, commonly fitted to 500cc Norton racing singles - This item

These spacers are 2.00" between stud centres.

Note: We can also supply 22mm, 24mm, 26mm and 32mm bore spacers by special order, as well as 3mm thick tufnell spacers - email us at sales@racingvincent.co.uk to enquire.

If fitting to other racing carbs - please note, these spacers are approx 2.00" between stud centres.  Although not an expert on GP carbs - I think some of the larger bore Amal GP carbs were larger than this, therefore these spacers will not fit those carbs.

Note on Amal TT and RN carbs fitted to Norton SOHC models:  the flange spacers shown in these photographs are alongside an original Amal RN 'Longneck' carburettor - for comparison purposes only.  Norton SOHC models fitted with TT or RN carburettors were always supplied with the 'Long Neck' variety.  There was also a far more common 'short neck' version of both carb types, and this is often fitted to Norton SOHC models - as the long neck type are comparitively rare.  It is not uncommon for those that do not have a long neck available to fit a short neck type - but to get the original 'tuned length', it is advisable to fit an (approx) 1" thick spacer between carb and head.  I have done this myself on at least one Norton I have.  Sorry, but we cannot supply spacers of that diameter, but occasionally they can be found at autojumbles - or the long way is to buy a block of ally and machine/hacksaw yourself!

Tufnol spacer flange to fit between cylinder head and 'flange' type carburettors - i.e. Amal TT/RN, Monobloc and Concentric carbs.  This listing is for a 32mm bore spacer, 6mm wide.  

These 6mm thick tufnol type spacer flanges were a common fitment on many models fitted with Amal flange fitting carbs.  We also provide two smaller sizes.

This larger bore is 32mm - which equates to approximately 1 1/4" in imperial size.  I know these were a size used on later Vincent Black Lightning carbs and probably other sports/racing bikes in the 1950's-1960's

These spacers are 2.00" between stud centres.

These insulatings seals are 3mm thick and this item is for an internal bore of 26mm (approx 1"), to fit flange fitting Amal carbs.(i.e. 2.00" between studs).  These thick washers can seal as well as insulating the carb from excess engine heat.. 

Price per each.

Thicker than the paper type carb gasket we also sell (Item 0452/0453) - and less thick than the Tuffnol spacer rings we also offer, these 3mm thick gaskets/insulating seal's provide a gasket face for Amal flange fitting carbs (with 2.00" between stud centrres - which covers most Amal flange type carbs), but can also offer more heat insulation for the carburettor than the plain paper type washer.  These are manufactured by a high quality specialist UK gasket manufacturer .

These are 26mm bore - which is very similar to the normal 1.00" 16H sdievalve engine, and close to the 1 1/16" bore used on postwar Norton 500cc OHV models.  I am supposing this type of gasket/inuslating seal would be useful when running cast iron head/barrels that get very hot in summer months.

These insulatings seals are 3mm thick and this item is for an internal bore of 32mm (i.e. larger bore, normally TT/RN/GP1 carb sizes), to fit flange fitting Amal carbs.(i.e. 2.00" between studs).  These thick washers can seal as well as insulating the carb from excess engine heat..

These are 32mm bore - which is a larger bore size, most suitable for racing carbss. I am supposing this type of gasket/insulating seal is useful if you have an engine running hot, as it keeps the carb cooler (and therefore denser charge)

These insulatings seals are 3mm thick and this item is for an internal bore of 22mm (approx 0.875"), to fit flange fitting Amal carbs.(i.e. 2.00" between studs).  These thick washers can seal as well as insulating the carb from excess engine heat..

These are 22mm bore - which is a small bore (possibly smaller flange carbs fitted to many lightweight or 2 stroke models of the 1950's/60's), but this size also lends itself to being carefully trimmed with a sharp knife, to be opened out to whateve size your own carb inlet tract is - important if fitting to a racing motor with a specific size of Amal TT/RN/GP bore, that needs to be carefully blended.  Obviously - if taking this route. . . . follow all normal safefy practices!!

I am supposing this type of gasket/inuslating seal would be useful when running motors that get hot, allowing the carb better insulation from that heat - and therefore a denser fuel mixture

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.

A pair of Dowty type sealable washers to fit 1/4 BSP Petrol Taps.  Price is for a pair of washers

These washers are a modern alternative to red fibre or copper washers for those petrol taps with 1/4BSP threads going into the petrol tank - of the type used on most Norton OHV, SV, Twins and CS1 models, as well as many other British motorcycles.

Note: in the photo on the left is a genuine Enotts style petrol tap as fitted to the Left side of many OHV/SV tanks of the 1940's.  This is identifiable because of the union at the base of the tap - which would have held an extension banjo to take fuel over to the other (drive side) fuel tap - which would have then fed the carburettor.  A domed nut was then used at the bottom, under the banjo fitting (rather than a fuel pipe to the carburettor, as on the drive side).  These taps are now quite rare - sorry, this one is not for sale.

These washers are not of the type used with the large 'Sump' type SOHC petrol tap - although we do sell the special red fibre washer for those taps - it being Item 0383

Throttle cable adjuster - of the type with tapered top hex, the same as fitted to original Monobloc and 276/289 roadgoing Amal carburettors.

as can be seen from the accompanyning photos, these adjusters look identical in design to the original design - as shown alongside an original Amal Monobloc cable adjuster - with slightly tapered hex top.  This type of adjuster were originally fitted to both Amal Monobloc and earlier 276/289 carbs without locknuts - as the tops for this type were normally threaded.  I believe they were also fitted to later Amal carburettors

Please check the top of your carburettor before ordering though - as some variations of carb tops for these models were made to take a non threaded ferrule - in which case you may want to fit the original design of throttle cable for that type, which normally had an adjuster mid cable.

Final point on these - as sold here, this listing is for the cable adjuster only - normally fitted like this when the top of the carburettor was threaded.  However we also sell the same adjuster complete with locknut - Item 0145 - which is useful if the top of your carb is not threaded, and the locknut can be used to adjust the height.

This item is a stainless steel oil/fuel pipe ferrule to fit black rubber style 5/16" internal diameter BSP pipe - of the type often used on Norton models for cambox pipes, breather pipes or similar - but this type will fit over pipe with an OD of 14mm. 

These are UK manufactured by a specialist ferrule maker.

Although 5/16" internal pipe bore is a standard BSP pipe size, it should be noted that many commercial fuel and oil breather pipes have different outer diameters - and therefore some ferrules will fit and others will not.  This particular ferrule is a good quality UK manufatured ferrule with an internal bore of 0.544"/13.8mm - meaning it will fit over fuel/oil pipes with an outer diameter of 14mm.  Notw we also manufacture ourselves a slightly bigger 5/16" ferrule, which will fit over pipes with an outer diameter up to 15mm - see Item 0979b (but they are CNC turned from solid stainless bar and far more expensive). 

Price is Each.

These ferrules can be crimped with a commercially available ferrule crimping tool - but often on breather pipes, all that is necessary (if the ferrule is a firm fit over the pipe, and is mainly to be cosmetic only) is to use a centre punch half way along the length of the ferrule to stop it slipping off.  If you are using it for fuel - as with all fuel pipes - it will require some form of crimping tool to ensu
