400/4 'O'ring list or kit

[adriangsmith]

Hi All,
currently rebuilding a 75 400/4 engine.
A top end strip so far shows no problems apart from rock hard 'O' rings throughout.
Does anyone have a list or sell a kit of the 'o'rings that are not included in the standard full gasket kit?

Cheers

Adrian

Hello,

   thought I'd jump on the bandwagon here and ask if anyone knows the size of the O-rings on the carburettor  connecting stubs (the black plastic double ended spigots between the carbs)?,

        Cheers, MikeJ

You could buy a kit of assorted O rings from Screwfix.   I bought a kit for work and I'm always raiding it for the bike.

91317-171-003   6x1.7   Cam tensioner adjuster bolt

Hope that helps !

Perfect Andut,
Just what i was After!
Theres nothing worse when ordering from DSS and you think you have everything and find that one crucial 'o' ring missing from the gasket kit that holds your build up for a week.
Thank you very much! :-)

There was more than one crucial O rings missing; quite a few crucial O rings.
