Trev's Vintage Machine Shop

This is a set of replacement 50mm long stainless steel carburetor studs with stainless steel nuts and washers to fit many British-made classic motorcycles including AJS and Matchless.

These are 50mm long overall to accommodate a 3/4in spacer with monobloc carb. Threaded 5/16 BSW and 5/16 BSCy, machine cut threads. Supplied with standard 5/16 hex nuts (1/4 Whitworth spanner size).

Please note that not all models & engines use the same threads, e.g. these don't fit the AJS IS 1965 Model 14 because it has different threads into the head. If in doubt, please check the threads before ordering.

These studs are manufactured in our own workshop here in the UK using high quality stainless steel, so they are an upgrade over the original parts that were only made from plain steel. They are far superior to cheaper, lower quality studs that tend to be made from threaded rod or long grub screws.

It contains 2 new studs, 2 stainless steel nuts and 2 stainless steel washers as shown in the picture. Please remember to apply a smear of copper grease or similar to the threads during assembly. All items are dispatched quickly via Royal Mail 2nd Class, with 1st Class available at extra cost.

Not what you want? Return the studs unused for a refund.
