Similar to part 0372 except shorter, this shroud is of the type used as the HT Lead cover on many Lucas magnetos, but as the photograph shows - can also be used as a shorter version of the advance/retard cable cover,  Price is each

Triangular magneto flange fitting 3 point paper gasket, as fitted to Vincent KVFTT (and BTH Grey Flash equivelant) as well as Vincent Comet/Rapide K1F/KVF and all flange fitting magnetos.

- Woven cloth HT lead of the type originally used on many competition and roadgoing motorcycles from the early 1920's through to the 1940's.  Ochre/Orange in colour with black flecks - this HT lead is sheathed in a durable and waterproof covering that gives a very authentic look - as per the celluloid covering of the original period HT lead.  Price is per foot

This listing offers a small selection of 18mm Spark Plugs suitable for those older models fitted with an 18mm Spark Plug thread in their cylinder head i.e. Norton 1920's models, WD 16H models and Douglas 2 3/4hp models.  Please read the detail listing carefully - as some 'Long Reach' types are no longer available, and alternatives are also listed.  This is a multiple listing item, also offering original type 'crushable copper' washers for both 14mm and 18mm spark plugs.

This listing shows a selection of brass fittings for veteran motorcycle spark plugs, as well as some rarer spark plugs and fittings (and a nice copy of the Veteran Lodge style brass cooling fins that fit over most spark plug types).  We have manufactured the knurled brass nuts for securing the HT lead on older motorcycles (i.e. pre spark plug cap) in two main styles and a variety of threads  See item listing for full detail and options

NGK B6ES Spark Plug to fit all Norton road going single engines, i.e. Model 30/40, OHV ES2/Mod 18/Mod19 and SV 16H/Big4.  It also fits Vincent 500cc and 1000cc models (Series B/C/D).  

I use NGK spark plugs on all my bikes now, I have found them to be the best of all modern plugs for quality and reliability.  The B6ES is equivelant to a Champion N5 and is the 'normal' roadgoing fitment for Norton singles and Vincent models.  The other common fitment for these engines was the B7ES (Champion equivelant N4) which is a slightly harder plug and may be more suitable if you prefer harder/hotter running.  I tend to keep at least one of each in my tool roll on road bikes, as spares - we sell the B7ES grade as well - Item no 0576

NGK B7ES Spark Plug to fit all Norton road going single engines, i.e. Model 30/40, OHV ES2/Mod 18/Mod19 and SV 16H/Big4.  It also fits Vincent 500cc and 1000cc models (Series B/C/D).  

I use NGK spark plugs on all my bikes now, I have found them to be the best of all modern plugs for quality and reliability.  The B7ES is equivelant to a Champion N4 and is an alternative to the slightly softer B6ES (item number 0575). You may find your engine runs slighlty better on this grade of plug if you often run at high speeds or your engine runs hot, as this is a slightly harder (colder) plug.

I tend to keep at least one of each in my tool roll on road bikes, as spares - we sell the softer B6ES grade as well - Item no 0575

- Standard black rubber HT spark plug cap. Suppressed

Classic 'Champion' spark plug cap, Type WCX600, with suppressor fitted.  A very popular classic model of HT spark plug cap, fitted to many british bikes in the 50's-60's.   

- NGK modern LB05EMH competition spark plug caps with resistor to protect against RFI interference - Waterproof and probably the best cap you can use if you are using the bike seriously - but not cheap! - I also include the small nylon tie band that NGK have stopped supplying themselves now! Aug 2023: Now back in stock!

This listing is for a bag of 6 small, neutral colour, cable ties - which are very useful for clipping to the rubber boots fitted over magneto advance/retard cables, rubber HT Pickup boots and those spark plug caps which have a rubber end.  Fitting these small cable ties very much helps prevent water sneaking in and affecting the electrics. Price is for a bag of 6 cable ties

These are the split brass washers that are soldered to the end of the HT lead that is screwed into Lucas and other similar magnetos that use screw in HT connections.  Using these washers give a good connection and retains the HT lead as the was.  Price is for pack of 4

Lucas early racing magneto serial plate. These were fitted to very early Lucas KR1 racing magneto's of the late 1920's and early 1930's, as fitted to the earliest CS1's and International engines. Very high quality reproduction plate in etched steel with black enamel infill

Lucas 'Racing Magneto' plate. As fitted to 1940's and 50's road racing NR1 and KVFTT type magnetos. Also fitted to Lucas 2MTT rotating magnet magnetos, as fitted to DOHC Manx Nortons from 1957. Very high quality reproduction plate in etched steel with red enamel infill

Lucas 'Racing Magneto' plate, with rounded ends. These would have been fitted to fitted to 50's road racing NR1 and some other similar type competition magnetos (very similar to the green label also used on some of these magnetos, mainly trials bikes, if green). Very high quality reproduction plate in etched steel with red enamel infill

This Lucas label, with Red colouring, is very similar to the extremely rare Lucas SR-R label, the racing magneto fitted to DOHC Featherbed Manx in the mid 1950's, prior to the introduction of the 2MTT rotating magnet magneto. In the 2nd photograph here, is my SR-R, with the remains of its original label. I am not sure why the reproduction label has an extra area of blank metal on the left of the label, but I think this will need to be carefully removed to fit into the indent correctly. Very high quality reproduction plate in etched steel with red enamel infill

This is the standard Lucas serial model and number plate, fitted to many Lucas magnetos from the 1930's to the 1960's. This includes the Lucas M01 Magdynos fitted to Norton Internationals and other Norton road models for many years, as well as KVF and K2F magnetos.

Lucas 'WaderMagneto' plate - in green. This plate was used on the Lucase waterproof magnetos, which were fitted to trials bikes and similar in the '50's and '60's era, Genuine Wader magnetos were quite rare, and I am not sure if the 'Wader' name was used on different body types, but the best known Wader was a variation of the Lucas Mad/Dyno type magneto - M01L, of which a photograph is shown. High quality reproduction plate in etched steel with green enamel infill
