Does this refer to the recent o-ring question? If so, care to share with the rest of us?
Drew400:
Yes indeed. I received a suggestion by PM hence not sharing, sorry.
I was shown a picture of an 'oil pump gaskets set' that had only two of the questioned O-rings therein. The two options shown in the parts catalogue are shown on David Silver's website to be of different sizes, 13.8mm or 15mm. I simply then measured the ones off my bike (15mm).
I'm still unsure as to why there are two sizes, but at least I got the answer I needed to progress.
Cheers,
D.

Thanks! I was curious about the two item numbers myself...

Did you ask Mark? Did you get a reply you can share with us?
There is a thread on the same site that might be worth looking at - it's "Branden's leak free top end thread"

Dear expert peeps,
Here's another inevitable follow-up question...
The oil weep clearing job has taken a little longer than expected (what's new?) thanks to one of my exhaust pipes literally falling apart from the collector box. Clearly, it's rotted through from the inside but only became noticeable when disturbed. Hey ho, some miracle welding from a genius welder mate of mine and it'll be ready to go back together next week.
During the intervening period, with no head on the engine, oil is now weeping from the cylinder base gasket area.
Does this mean I now have to remove the block and replace that gasket, or will it seal up again when the head if finally reattached and torqued down?
Ta, D.
