i have had my 850 cylinders bored to +.020 and have a question...can I use norton villiers genuine spare part 26640/k +.020 piston rings fitted to Emgo 850/77MM +20 pistons? Should I be using emgo rings? And should I be fitting new circlips on my gudgeon pins or ok to reuse the originals?

Unless you've taken measurements (ring thickness and width/land clearance etc.) I would stick with the Hastings rings so many Emgo kits come with.

I would use new circlips, providing they are of good quality and are secure in the recess.

The JCC pistons I bought had the round wire circlips, I pressed some blu-tak into the circlip groove on the piston and checked the impression for shape and width, square groove and 1mm ish width so bought the proper circlips.
