If it was a crack I can't envisage a catastrophic failure likely.

I agree that I don’t now think it is a crack. If it was manifesting itself from the outer edge of the disc it would be plausible. Having had a good examination of the mark under magnifying glass and good light I’m quite sure it is just a scratch.

Might be a daft question but are still able to get hold new discs or is it a case of getting hold of a second hand one that still has plenty of life left in it.

Another one done, with a final bit of tensioning it’ll be ready for a tyre!

Do you have to grind off any excess spoke ends on the inside of the wheel or does the tape stop it lancing your inner tube?

No excess spoke Ted! If they are the correct spokes for the rim they and hub they should be sound. The tape will undoubtedly cushion the seat for the inner tube, I suppose there could be small burs on the nipple ends if it had been built using a screw driver. I just use fingers and spoke spanner.

Impressive! I need at least my rear wheel rebuilt with new spokes and rim but I don’t know if I can work up the courage to do it myself; it would be a first for me.

It's really not that hard Mike once you've watched a few videos, the critical bit is getting CWC to send you the correct spokes, they've got mine wrong twice out of two builds.  Quite enjoyable really.

Onward we go. Could have done this with the engine in frame but glad I removed from frame this afternoon. Definitely worthy of a top end rebuild!

I've seen worse NJ's 400 strip down springs to mind - it's amazing it ran as it was when the pistons were out.

Looks like number 1 cylinder was  a tad leaner than the others - but not massively.
