As in just sand it smooth??

Nurse Julie:
Trig says just remove the burr with a sharp instrument, and then use a very fine wet and dry around a dowel. Trig would ream it.

Sweet, I'll give it a go

Bryanj:
Shaft does't turn in there anyway so as long as its a decent load surface it's OK

Yeah only just realised that! I though the shaft turned in the cam towers rather than the rocker arms turning on the shaft   ;D

Sanded it down anyway and it's all smooth now.

Assembled the rocker arms no problem and then came across a baggy of 8 little metal 12mm cylinder pin things suspiciously like the ones that go between the cylinders and head.. doh! Definitely not ideal going so long between stripping and reassembling.

I remember installing the 8 rubber bits (which sit around the metal pins) and remember thinking at the time they seemed a bit loose just sitting there..

How much of a risk is it to leave as is? What's the purpose of the metal pins?

I have the creeping feeling the head is about to come off again!

EDIT: seems these metal pings weren't present until the K3, probably missed them out as I was following hondaman shook where he rebuilds an earlier bike.
