Norton Commando 850 MKIII Service and Recommissioning. Part 23: Helicoiling Z Plate, Gearbox top up

This video is part of a series covering the recommissioning of this 'Norvil' Norton Commando 850 MKIII Roadster. It was built by Norvil in 2012 using new and upgraded parts throughout, including uprated brakes, electrics, starter motor and various upgraded engine parts etc. etc. However, shortly after it was built (only 900 miles on the clock) the then owner decided they didn't like it (too high and heavy for them) and left it sitting in their shed - for 10 years! These videos follow the recommissioning of the bike after its long slumber. This particular video shows a helicoil thread insert being used to repair one of the threads in the right hand Z plate, followed by the oil in the gearbox being checked and then topped-up.
