Re: Reclaiming rotary engine components.

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...

Norton Rotary New Rear Chain Gaiters

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...

Re: Good evening

The oil must be low ash, I use Castrol Tection DD40, Shell Rotella 40 is recommended, some Rotary owners use a Silkolene oil

I suspect if Morris straight 40 Golden Film was used it would carbon up very quickly

The centre plate on My Commander had a plug in the tapped hole, if the air cooled are the same could your plug have been removed or dropped out? To remove the engine is not a big job on my Commande...

Funny little ways

This may be of interest to some Commander owners. Having owned and greatly enjoyed my Commander for a number of years I have found that after a winter layup and the first run of the year the bike is just not happy until it’s covered around 100 miles, this may be owing to the way I lubricate the roto...

There is a difference between cooling water temperature and exhaust gas temperature, anyway let us know how you get on with the new plugs.

Re: Boyer ignition

David,

I agree, however I feel the Boyer gives a more even tick over, I have been told that the Boyer and Mini Mag use a different retard setting, that said the Mini Mag is good system.

All I have to do now is save up for a new one to carry as a spare.
