Hi All,

Does anyone have or know where I can get a list of all o rings sizes for the engine?

Thanks...

The A65 engine only uses a handful of O-rings and some of these are available from parts suppliers under the appropriate part numbers. For less critical ones, for example, as a seal for the oil release plug, it is normally sufficient just to pick an appropriate imperial size from an O-ring set.

Thanks Arthur,
I was hoping to get the sizes and buy Viton rings to ensure quality.

I am building a couple of bikes from bits and pieces and have a A50, they are a mixture of years so I am compiling a reference manual for each of my bikes for the future.

Best wishes...

The sizes of some of the O-rings are available. What year is your A65?

Hi Arthur,
The cases are the later design 1969 - 1972, I have not had them specifically dated as yet.

Best wishes.....

Hi Arthur,
