Last Update this year I guess
Why is it so satisfying when you get to try the tank on for the first time

Engine coming along nice at Buzzworkz (Z1 Club Buzzard)

Some nice reference pictures
All the inevitable broken studs milled out and Helicoils fitted.
Clutch plates

[BigZCas]

New valve guides fitted.
Valves polished and seated.

And so the assembly begins

Lovely bag of goodies there, ready to go back into some beautifully clean casings!
Couldn't help noticing what looks like a crack between the plug hole and the ex valve seat on pot no.2

This is an awesome thread

[buzzard]

Ref crack between exhaust seat and plug thread. This is a thing that occurs quite often and I've seen it In lots of heads in the past nothing to worry about. I reckon half the heads ive done have the odd crack in them. Buzzard@ thebuzzworkz.

Quality!!!!!!!!!

[BigZCas]

Picked up the engine from Buzzard on Sunday, very pleased
so I made sure the frame was wrapped with Copex, great stuff very tough, there is no way the frame can get damaged using this, would recommend.
Invited my son and mate round to give an hand, the 3 of us put it straight in without incident.

What size/type of copex did you use?
