but size for Centre tank- Exhaust downpipe diameter
« on: December 09, 2018, 03:03:09 PM »
I have a 1977 Triumph Tiger TR7V.
I have forgotten the nut size of the Centre tank nut?
Also the diameter of the exhaust down pipe? I think it’s 350mm?
Can anyone help

350mm would be the diameter of the exhaust pipe on the QE2! ;)
From a (very distant) memory, the nut is 5/16" UNF.

The tank mounting nut and stud is 5/16UNF, part numbers 14-0302 and 83-4930. The diameter of the into head exhaust on my ‘77 Bonnie is more canal boat size at 35mm.
