Re: Hello to all

Hi Mike Welcome to the forum. Regarding the Commander they are quite tall and heavy. The weight is due to all of the fibreglass bodywork. Exotic and fragile they are not. Everything apart from the engine is pretty standard, much comes from the Yamaha XJ900. My Commander has been all over Europe as f...

Re: Brochures and booklets

Hi Terry, from what I can remember from my last visit, Andover Norton has a number of contemporary booklets and brochures from the Rotary period. I don't think that brochures are in any way rare because so many were left over when production ceased. Regards, Tim

Re: Wits End

HI JB, the factory setting for the carburettors is designed to fast idle when the engine is running in, this clearly does not apply to your engine which should happily idle at 600 rpm. I can't assist with the electric waterpump. The standard version is mechanical and therefore speeds up as the engin...

Re: Wits End

Hi John A fat spark doesn't always mean that the plugs are operating properly. A change is a simple task, Next borrow an electronic ignition box and try it, Ok so the ignition probably isn't the problem but once you have tried these two simple checks you can then concentrate on the carbs, If they ar...

Re: Reclaiming rotary engine components.

The rotor bearings are slightly different, one is hard to source and the other may become so. If JB used a secondhand one that may have been the problem but that may be the only source at present and they will need to be carefully checked. These bearings seem to generally have a long life. It would ...

Re: Norton F1 questions

Hi Harry, first of all is it an F1 or an F1 Sport? The latter is indeed very rare and the F1 is certainly an uncommon bike to see around other than occasionally at Norton Owners Club events. The F1 Sport usually achieves higher sales values although there are so few for sale it depends on how much s...

Re: water pump capacity

Hi JB, the water pump is no more than an impeller on a shaft supported by bearings attached directly to the rotor shaft by means of an olham coupling. Its output is entirely determined by the speed of the engine. Think of an old fashioned car water pump driven by the fan belt. I don't know if anyone...

Re: Forum Spring Clean

Hi David some of us are lookers rather than posters. I accept of course that if everyone was the same in this respect there would be no posts at all. One thing that may be worth a look is how to improve the announcements section. Many of us attend various local events and camping weekends etc and if...

Re: Water Pump

In my experience the water pump is the least reliable component on the Commander. Just three weeks ago my bike boiled near Bordeaux on the way to Spain. The oldham coupling had worn to nothing on the impeller side. i had a spare with me and I was sufficiently close to an aire de repose to coast in w...

Re: Starter solenold

Hi RogerI also meant to say that before you start the bike take the plugs out and the air filters off and sqirt oil into the chambers through the plug holes and induction ports then move the bike backwards and forwards in gear so as to get oil within the engine. It will still start even with a consi...

Re: Starter solenold

Hi Roger, you would be better off posting in the technical interest section, this section is hardly used. This may seem too obvious but the symptom you describe is exactly what happens if the kill switch is in the off position. Also there are two ignition fuses, I should check them. As far as I know...

Re: New owner

HiI hope that you are enjoying the Norton. If you have a Commander with Yamaha XJ 900 forks then there is a straightforward mod which is fully explained on the Startright website. It involves putting in aluminium an insert (although i used hard plastic). the bike wallows less and i am very pleased w...

Re: Moly Coating

Hi AllFollowing on from Richards post, the main reason that the NOC restricts postings to members is so that it can require members to accept the club's rules with regard to content. Postings that are offensive are relatively few but can cause considerable damage to an organisation that owns the web...
