Good to know Bernd, was thinking about both methods -rear sets and reversing camplate, or rod/to rear gear change off rear footplate, reversed the thing when I did it just in case at the time.
One other decision with the Norton box of whatever flavour you have is the oil feed pipes -to try to follow the original routing, or under the gearbox coming up just in front of the RFM pivot under the battery tray and connecting to the UFM oil tank that way. I tried to keep it original, but found two issues -I needed to cut the feed pipe a little shorter (level with the inspection cover in photo), then tucked under the decompression cable (gets tight at that point and I'm thinking of making a tab to hold the oil pipe off the decompression cable), then threaded through the gap between F106 body and the bolt through the 'new G50', adjusters/top of the Norton gearbox flange, ain't pretty, but it's out of sight and a little protected -if seen in conjunction with David's instructions the second photo should make sense-
Alternatively, could just run it up between engine gearbox as normal, trim pipe, tuck behind G50 and up around F106 to the oil connector, much easier- I just wanted the pipes hidden away where possible...
