    Default O ring thickness

    Anyone know what thickness the o ring is that goes between the engine & the primary on a '71 FLH ? I've got a James gasket set and there are three of them . Thanks , Mike

    The ones I have in stock are Cometic and measure aprox. .070. It should be the the skinny one in you kit.

    Be careful. If you use the wrong one, when you torque the inner primary, you will break the ear on the front of the primary. The thin one is the correct one.
