- This is the throttle cable adjuster and locknut as fitte d to many later roadgoing Amal carbs, however the thread size is 7/32 x 40tpi, and if fitting to a later Amal TT carb - you should check what thread type (if any) is already fitted - as some later Amal TT caps had different threads (or no threads at all, in which case a cable cap is often fitted - or the adjuster is stopped in place by the locknut on the adjuster alone).

Note - these are modern type adjusters from a UK manufacturer and will fit both Amal TT carbs as well as Monoblock/Concentric models.  They are high quality, but if fitting to replace the original early Amal TT/RN type threaded adjusters on original carb tops - they are slightly  slimmer diameter, so will require a small washer under the locknut, so as to give full purchase for the cable . 

Note also - if you have an earlier Amal TT or RN fitted with a brass top cap - these were normally fitted with a distinctive knurled top cable adjuster - particular for that model (normally 1930's to early 1950's TT/RN carbs) - we also manufacture that earlier and wider type of adjuster - See our Item 0874

These also fit the Amal TT type top alloy chamber tops (Item 0138) we manufacture - if you have previously bought one of these tops, which are threaded for this type of adjuster.

This listing is for a universal type throttle cable of 37^ in length, with nipples fitted either end - to fit most twistgrips and Amal carburettors.  This cable type has an adjuster in the middle of the cable (about 6" below the twistgrip). 

Price is Each.

This cable type comes with a small barrel type on one end (of the type that fits in all the twistgrips we sell), then a cable adjuster and locknut about 6" further along the cable (i.e. ideal for being adjusted when sat on the bike, just below the handlebars), and with a small cylinder ferrule at the other end - of the type that will fit most Amal throttle slides (including TT, RN and GP).

It should be pointed out though that if you are making cables up for competition TT, RN or GP carbs - and are intending to use our 'original type' air adjuster kits or throttle cable adjusters - that fit into the body of the carburettors - then you will need to unsolder the barrel at one end, carefully grind the cable to a point - so the barrel can be removed, then the outer cable adjusted to account for an new adjuster that is fitted.

We also sell a spare throttle cable outer cable ferrule, and inner cable barrel ferrule (i.e. the twistgrip end) as a seperate item - Item 1218, so if you are modifying the cable, and do not have a box of ferrules . . . you can fit a new outer cable ferrule if you have trimmed this cable to length, and fit a new inner cable barrel if the one that comes fitted is unusable (see Item 1218 for more information)

Although not listed - I should also be able to help with extra ferrules and cable barrels - and may be offering them in the near future (this update in January 2024). Also, if you email me on paul.norman@racingvincent.co.uk, I can provide more information on this cable setup process - it used to be a normal part of any 'Project Build' - making up all the cables to fit your particular motorcycle - but if you are doing this yourself for the first time - remember to 'tin' the cable before cutting or grinding it, and use plumbers solder rather than electrical solder.

This listing is for a universal type throttle cable of 37^ in length, with nipples fitted either end - to fit most twistgrips and Amal carburettors.  This is the 'plain' cable type - i.e. there is no adjuster fitted along the cable length.  

Price is Each.

This cable type is useful if you are fitting it to a carburettor or twistgrip that has its own cable adjuster already fitted.

In the case of twistgrips - some twistgrips come with a cable adjuster which is 'slotted' along its length - in this case, you may find the cable can be used just as it is (i.e. it comes with the ferrules either end already fitted, to fit most twistgrips and Amal throttle slides) - as the inner cable can be fed through the slot, without having to remove an inner cable ferrule to slide it on.

However, the main reason we list this type of cable, is for those customers who are fitting an Amal competition carburettor such as the Amal TT or Amal RN (for which we sell many parts, including - the original type cable adjusters particular to those models) - and want to fit cable adjusters particular to that carburettor type - either throttle cable, or air slide cable.  In this case - of course it will be necessary to heat one cable end up, to release one of the ferrules, and then feed the required adjuster on to the cable - and probably require the outer cable cutting to length, before re-soldering.  To do this it is expected you will be familiar on how to 'make up' cables yourself (i.e. tinning the inner cable, how to grind the end without fraying the strands etc) - but if you need help with this, you can email me at: paul.norman@racingvincent.co.uk.

We also sell a similar length throttle cable with a cable adjuster fitted midlength - this is Item 1216.  It should be noted though that that cable has a 'top hat' type outer cable ferrule on one end, which means it can be dropped into a carburettor top with no thread - while this cable type has a plain outer cable ferrule at both ends (i.e. it will just drop through a carburettor top, if the top was intended for a cable adjuster.

As a final note on this - if taking this route (i.e. removing the ferrule from one end to fit an adjuster etc) - we can also offer a useful small item -  Item 1218 - which consists of a spare throttle cable ferrule - of the type commonly fitted at the twistgrip end, and one outer cable ferrule, which can be fitted over the end of this outer cable, if you have trimmed it to a new length (I normally use a small sharp punch, to slightly punch the ferrule after fitting over the cable outer, to stop it coming off).

Also, if making up cables for yourself for the first time - remember to 'tin' the cable before cutting or grinding it (to help prevent the cable strands splaying), and use plumbers solder rather than electrical solder, as well as a good quality soldering flux.  and FYI - do not put any oil on the inner cable where you are intending to solder - they almost never 'tin' once impregnated wtih oil.

This listing is for a spare Throttle Cable (or choke/air/magneto type cable) outer cable ferrule, and a spare inner cable barrel of the type normally fitted on the twistgrip end of throttle cables. 

This item is useful if you have bought a throttle cable (see items 1216 and 1217) and need to then cut the cable to length or fit an adjuster.  

Normally to amend the length of a cable, or fit an adjuster, requires that the outer cable has to be trimmed to a new length - which loses the pressed on cable end ferrule that it comes with.  Therefore this spare outer cable ferrule can be placed over the newly trimmed outer cable to protect it.  When making up cables - I normally use a small sharp punch and give this ferrule a small punch midway along its length, to stop it slipping off in use.

Likewise, the inner cable barrel ferrule can be used to replace the twistgrip end ferrule, if the original is not re-usable after amending the cable.  But make sure you check this barrel type fits your twistgrip (or air/magneto lever, if being used for that purpose) before fitting!

You can email me on paul.norman@racingvincent.co.uk if you require more information about making up and soldering your own cables - or require other ferrule types, I may be stocking more types in the future.  Also - read the listings for Items 1216 and 1217 for more information.

This very useful little item is a 'Top Hat' Ferrule - is to fit original Doherty and other similar throttle twistgrips, which are not threaded at their cable end - and if you are using a throttle cable which has its threaded adjuster in the middle of the cable, not on the twistgrip end - therefore this 'Top Hat' ferrule will stop the cable sliding through the twistgrip hole. 

Background to this item:

We offer both original Doherty throttle twistgrips (Item 0942) and a cheaper offshore version.  Many people (myself included) still like to fit an original branded product if available - for originality sake.  However - the Doherty type twistgrip does not have a threaded end and adjuster fitted - instead it relies on two types of throttle cable fitting:

- A throttle cable that has the adjuster at the throttle twistgrip end, and a nut on the adjuster - then when the cable is fitted, it is the nut that stops the cable from dropping through the twistgrip cable hole

- OR:  if you have a throttle cable with the adjuster mid-cable  . . . and the end of the outer throttle cable is just the normal cable ferrule (normally 0.220"/5.5mm diameter or thereabouts on most old British Bike throttle cables) - then it would normally be necessary to fit a 'Top Hat' ferrule, which slips over the end of the inner cable before fitting it to the twistgrip - and that slides into the end of the Twistgrip, holding the cable outer captive, stopping it from sliding through.

This style of Top Hat used to be available many years ago - I remember seeing them myself at autojumbles and used to have a couple in my cable tin . . . but when a customer pointed this out to me some months ago (when purchasing a Doherty twistgrip) - I could no longer find a manufacturer or supplier of them.

So - we have now manufactured this useful little ferrule ourselves  - they are CNC manufactured from stainless steel - and are also mill/slotted, so they can be slid over the inner cable, without having to remove the bullet at the end of the cable.

Note:  These only need to be used if your throttle twistgrip does not have a threaded adjuster already fitted (i.e - our similar offshore twistgrips are threaded and do have an adjuster

The dimensions are as follows (in case fitting to an original twistgrip or other type of twistgrip or similar):

- Diameter of Top Hat - where it slides into Twistgrip hole: 0.306"/7.8mm

-  Receptor hole for receiving throttle cable ferrule: 0.223"/5.7mm

- Slot width, for sliding throttle cable 'inner' wire through: 0.081"/2.00mm

Please satisfy yourself this is satisfactory for your purposes - and follow all normal safety practices when fitting throttle cables

CNC manufactured by us in stainless steel.  Price is each

Sorry not cheap - a suprising amount of machining (including milling) to make this tiny item!  However we discount this item to £4 if bought at the same time as a Doherty twistgrip from us (Item 0942)

Useful little box key spanner for fitting and unfitting main jets on most Amal carbs that used the standard type Amal Main Jets (as shown in photo).

Nice quality and very useful to keep in your toolkit . . . saves trying to find a spanner to fit!!

Castrol ValveMaster Plus - Lead Replacement Plus Octane Booster - 250ml Bottle.  If your Norton (or any other classic motorcycle) has not been fitted with new 'unleaded' type valve seats, then using modern unleaded petrol will lead to excessive wear of your valve seats.

Castrol offer Valvemaster Plus to combat this problem - just add a small measure of this liquid to your fuel tank each time you fill up and you will effectively be changing your 'unleaded' specification to 'leaded type - and therefore will protect valve seats.  

Note: Castrol make 2 versions of this lead replacement additive, a standard version, and then this version which also has an Octane booster included.  I always add this version to my British motorcycles - as I want to provide as high as an octane rating as possible to the high performance engines we are running (SOHC Nortons, sports twins etc), to reduce the possibility of pinking.  Therefore I use this in all my classic bikes.

However, should any more encouragement be needed - it is also endorsed by the Federation of British Historic Vehicle Clubs.

This 250ml bottle will treat 250 litres of fuel (1ml to each litre of fuel).  The reason I like this Castrol lead replacement offering over other makes is that the bottle includes a clever measuring device at the top - just squeeze the lower part of the container until the correct quantity of the additive fills the top measuring holder, which is graduated with the different quantities of fuel you are filling your tank with - simple!

Always read instructions before use.

Float needle to fit the Amal 276 type floatchambers and the early (mainly pre-war) type floatchamber.  Note: these float needles are of modified design to the original, with two grooves - which allows them to be used with the orginal copper floats (which use the groove furthest away from the cone) and the modern plastic type floats (which use the lower groove, closest to the cone)

Background: Amal TT (and RN) carburettors are more commonly fitted with Type 14 alloy TT floatchamber, which is identifiable by having a large Hex bottom feed/banjo, and used a different (wider at the base of the conical section) float needle to the one shown here.  To look at a float chamber of that later type - see our Item 0163.

However, earier TT carburettor's, particularly many of those fitted to SOHC Norton models pre-war used the earlier TT type float chamber, which was similar in build to the Amal 276 float chamber (road not racing), and both of these used the float needle shown here.  If you are unsure - the widest part of the cone for this needl2 is @0.222" diameter at the widest part of the cone.  The later competition type TT/RN floatchambers (normally in alloy) are wider than this - and are sold as item 0161.

This needle was also fitted to the road type Amal 276 float chamber, which used the standard pewter type alloy and had 'Amal' logo cast onto its body.  The pre-war type Amal TT float chamber was a different material, and did not have the 'Amal' logo on it.  In the accompanying last photograph is a picture of two original float chambers - on the left is a standard Amal 276 float chamber, with 'Amal' cast in side, on the right is a genuine early TT float chamber - which is different material to the 276 type.  As can be seen though, both types use the same bottom union and this type of float needle (note the banjo of the TT carb is of smaller centre diameter than the later TT Type 14 float chamber shown in Item listing 161).

Driven Defender and Booster - Lead Replacement Plus Octane Booster - 295ml Bottle.  If your Norton (or any other classic motorcycle) has not been fitted with new 'unleaded' type valve seats, then using modern unleaded petrol will lead to excessive wear of your valve seats.

Driven is a well known specialist American oil company, producting oils and additives for the motor racing industry - and one of their products is this fuel additive that protects valve seats on older style 'leaded' engines, as well as increasing octane  - just add a small measure of this liquid to your fuel tank each time you fill up and you will effectively be changing your 'unleaded' specification to 'leaded type - and therefore will protect valve seats.  

This 295ml/10 Fl oz bottle will treat up to 25 gallons (not litres . . . remember it is a US company!) of fuel.  The bottle has graduations along its side, along with a clear plastic area so you can easily see how much additive you  are adding on each fill up. 

I have recently stocked this item because other UK additives have been getting harder to find - and it is supplied by my main racing fuel distributor, so know they can be trusted.  I am using this additive myself now in my roadgoing Vincent and will report back results later in 2018
