[928uk] High Mileage Nervousness - Cam Chains

[Paul via 928uk]

Thanks Geoff - Ace Cafe and a curry is definitely on the cards, especially
if you can fathom a 'no start' on the Cerb.

The best thing about the 'Cerb no start' was that I got to do the Ring
again in the 928, and did some really clean laps that made me very happy.
I'm tempted to sort out the wheel/tyre situation now which I never thought
I would!

Hope you have some time free from your roofing exploits!
