Hello everyone, I have owned a 961 Commando from new in 2016. When i received it it sounded like a guy hammering an anvil. So bad that I returned it to Norton who said they did some 'adjustments' but nothing worked so....... after a lot of head scratching and using my engineering knowledge and some work carried out by a couple of machine shops near , I engineered a remedy. I've decided to share that remedy after riding it for some miles.
Firstly I will explain why the primary gear literally 'hammers'., if it hasn't already been posted (please bear with me if it has). Simply the intermediate split anti-backlash gear can never work between two gears. This is a fact and can be confirmed by any reputable gear manufacturer. Anti-backlash gears can only work in one direction. So what did I do ? I managed to blag some spare gears (primary and intermediate anti-backlash) from a guy who held a lot of sympathy in Norton back in 2015/16. This gave me the opportunity to think and try solutions. Although the gear drive train will, never be super quiet (unlike my Triumph Bonneville America) my 961 is significantly quieter.
I have just stripped out the primary gear drive train to check all is okay and taken the opportunity to take photos . If any one is interested in what I have done then click on my thread and I continue this thread with what I tried...what failed and what worked over the next week or so.. with photos etc.
