I have a Triumph Tigress 250 scooter 6v electrics.When I put a multimeter on the battery when the engine is running the readings are all over the place.When I put the sidelights on they calm down a bit,but range from 0.9 to 8v.Any other way to check the battery is charging,or ideas as to why this is happening ?

British Bikes / Auto advance
« on: January 29, 2019, 10:12:20 AM »
Having trouble firing up my Tigress.Ive got good spark and wet plugs,but only getting the occaisonal pop.Could the auto advance which looks standard Triumph effect starting,or does it come in later ? The scooter was standing for many years and I cleaned the auto advance up,but it could be a little stiff.

British Bikes / Nut Sizes
« on: December 03, 2018, 08:47:22 PM »
What nut bolt system was used on late 50/early 60s Triumphs? I have a Tigress scooter and cant work out what system was used.I have a front wheel nut which is 0.9 inches 23.3 mm which is apparently 1/2 inch whitworth. Got a whitworth socket set(modern) and the 1/2 socket wont fit. Is this because its modern? Ive heard they dont fit older nuts. This has been one of the biggest delays of the whole project.

British Bikes / Polychromatic/Shell blue.
« on: November 20, 2018, 08:43:59 PM »
I have a Triumph Tigress scooter. Im told its  blue colour is either polychromatic blue,Im not sure of this as a spray can I bought is way too dark ( this is for sale btw)or shell blue. It seems to be the pale metallic blue of the Triumph bikes. A search for polychromatic gave pictures of the paler colour,anyone shed any light on this thanks.
