Price is per foot. - I use this on my rigid and plunger framed Nortons - Note: Recently a customer informed me that the HT lead got soaked in the rain, and the spark was lost, as it shorted across the cloth. Please can I suggest that if you use the bike in all weathers, you may want to cut back the cloth 10mm on each end where it feeds into the Pickups, to minimise this.

NGK Spark Plug B6ES: Norton SOHC/OHV/SV and Vincent 500/1000

Product no.: 0575 NGK_B6ES

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 Spark Plug B7ES: Norton SOHC/OHV/SV and Vincent 500/1000

Product no.: 0576 NGK_B7ES

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

Lucas Red SR-R Type Racing Plate

Product no.: 0366 LUC 004

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.
