Spark plug cap

Didn't actually need it as the spark plug cap screws to the HT lead was found loose when removing, this had been causing the spark to jump from under the cap to the engine casing. Fitted new cap anyway, took all of 30 seconds to fit.

Plug caps of joy 🤩

Fantastic, I was having trouble with my plugs arching onto the valve cover of the Triumph and I remembered a bike that I had years ago doing the same thing and gave me no end of running issues, so I bought original plug caps and plugs from triumph and cut the HT leads back a cm and checked the coils earth and bingo no issues.
Great customer service from Triumph over the phone and really fast delivery service, a little on the pricey side but for my personal tastes I think my motorcycle deserves the best as it gives me loads of pleasure 😎
