Rotary Owners' Club

As everything else on the front end is Yamaha I would guess that the original bars are also Yamaha.

Have a look at https://www.ebay.co.uk/itm/373109560911 ... olid=10001

The running lights are aircraft landing lights, I have bought a few over the years there are numerous suppliers in the UK if they do not have any in stock you have to wait a while for them to arrive from the US https://flywat.com/.../legacy-landing.. ... ts/7034604

Dean, In my line of work we only mix oil types if the manufacturers advise if the oils are fully miscible. In our vessels main gearboxes we use a synthetic oil, which we know is not miscible with a mineral oil, so I would suggest your current oil and the Silkolene is the same. As there is little oil...

Philip, One of the excellent features of a Commander is the enclosed rear chain allowing the chain to be lubricated with 20/50 mulitgrade oil, the enclosed rear chain comprises, amongst other components, two gaiters one top and one bottom, sometimes the gaiters will fail so it is always very useful ...

Phillip,

Welcome to the club

Tony

Alan, At 235KG kerb weight they are not as heavy as some modern tourers, binding brakes may make it feel heavier than they are. If you do not have any rear chain gaiters as spare, always handy having at least one on the shelf, contact Chris Harvey chris.harvey33@ntlworld.com. Chris; using the origin...

John,

It may not be a straight forward as a simple relay, modern cars use can bus systems, my advice would be to seek professional advice from either the dealer or a good auto electrician.

Tony

The attached corresponds with my Commander, hope it helps

It it a modern car?

Roger,

Happy New Year John

Roger/John,

When the original Boyer unit failed while in the IoM 2019 I fitted my spare previously set up Mini Mag to my Commander, I did not change any other components, trigger or coils.

Tony

Roger,

My battery is lead acid, very occasionally topped up with distilled water.

Tony

John,

I converted from two batteries to one for my Commander many years ago, the battery pictures is at least 4 years old, and is still in good condition.

Dave Edgar ??

Making use of perfect biking weather I skived off work and did my most favourite ride over the Spittal of Glenshee, it is truly exceptional even more so when the weather is so good, my route was from just North of Aberdeen, Braemar, Spittal of Glenshee, Montrose, Cain o Mount, and home approx. 180 M...

David,

Not air cooled but my Commander at 4k RPM on the speedo reads 70 but the sat nav indicates 65, for a sat nav 70 I need to maintain 4.5k RPM

Tony

Paul,

They could be Yamaha XJ900 Diversion you could try Yambits

Tony

Roger,

I have used from the start NGK C8E 7471 with no issues.

Tony

John,

I hope you are well.

Changes in the 10% rule is news to me but that said I am not surprised, I will ask my colleagues at the next blood bike group meeting and will get back to you if they they know anything about it.

Tony

Marco, Running any engine without oil is not good, I run a Commander and have no experience of F1's, Richard Negus who often responds to questions on this forum is the only person I know who has the knowledge you need, you could try sending him a private message. Good luck and please keep the forum ...

The Norton Owners Club provide such a service, I used it to date my 650SS

Miles,

If anyone can help it will be Richard Negus, who often contributes to this forum, you could try a PM.

Tony

John,

So far no issues with ethanol, neither Commander or 650 SS

Tony

Thank you Richard for the interesting info concerning the lever plate, restricting the tap to only 'on' or 'reserve', both controlled by the vacuum fuel valve. I have only once run out of petrol when in the IoM, coasted to the side of the road, less than 5 mins to switch to reserve and away again, I...

John/Geoff,

I hope I am not tempting fate but I have not experienced any issues with the fuel tap, either leaking or the issues of the carbs drying out

Perhaps I have just been lucky

Tony

Roger,

I should have added that the oil level switch only has one black wire

Tony

My Commander oil level switch wire is black where it emerges from the frame then a short distance to a bullet connector then RW red/white to the loom

Roger, I find that the Norton Rotary Enthusiasts FB page is interesting, but mainly for those interested in the racing bikes and owners of F1's, that said there are some post concerning the non sports bikes. The Rotary Owners Club is an excellent source of information on the Norton rotary's i.e. Cla...

Its thanks to Chris Harvey’s hard work that I now have two brand new rear chain gaiters. This means that I will be able to keep my Commander on the road for the foreseeable future, these bikes are not designed to be used without the gaiters as they provide an oil bath and subsequently the lubricatio...
