tippy 98 help!

[nat]

Hi all,
can any1 out there tell me how many internal valve 0-rings a tippy 98 should have?
a m8 has got 1 2nd hand! we 've looked at the parts diagram on tippy's web-site,it seems unclear,
I know there's 1 on the valve plug,but should there be another in the valve anywhere?

any help appriciated.

I'm about 98% sure that there's two, one in the front and one in the back. Good luck replacing 'em too, it's a major PITA getting it out of it's housing.
