Rotary Owners' Club

Hi everyone, I've bought myself a high speed scanner.:-) For fun the first try is a copy of a large folder with a lot of technical information on the development of the F1 and RCW engines. If anyone is interested I have many engineering drawings, technical data sheets etc. I am very happy to share w...

The F1,F1 sport, and Commander usually have a flat beam, as used in America.
This doesn't illuminate the near side as well as a left or right dip but is OK to use in most countries.

Hello Dave, Wonderful to hear from you. Glad to be alive against the odds :-). Well, I created the site all those years ago, I'm so pleased to come back, probably 10 years later to see it still doing what I hoped it would : Carry on without me. I DO need people like yourself, willing to put in the o...

In my limited knowledge of the DKW/ Hercules 294cc rotary, the compression ratio has never changed from 7.5 to one. Later engines (Black tank bikes), had a mikuni pump to provide 2 stroke oil instead of the pre-mix of the 'red tank' machines. I don't think the yellow tank prototypes were much differ...

Hello John, I will bring home my box of Starter motor parts in the next few days. But if it's urgent, ring me on 07905291261 and I'll ask Antony to bring me all we have on monday. I've plenty of armatures and can provide you with any parts you need. I know you are very capable of building your own. ...

It's funny really, I created the forum to help norton rotary riders, We do keep silkolene rotary oil in stock, but cannot compete with the R.O.C delivery by friends system. Startrights is here if you get stuck,but please DO support the rotary owners club oil scheme. The few pounds we make on 4 litre...

Hi,
Please can you point me in the right direction
Graham.

Excellent, thanks.
Graham.

Are any forum members willing to share the task of policing the forum and adding new members.
It's not an onerous task, once shared with others...

Air cooled endplates are cast using an alloy that can withstand some pretty serious abuse, certainly a good deal more resilient than the much softer water cooled endplates.A good running air-cooled may not need moly coating. BUT!! All water cooled engines are cast using a different alloy, it's softe...

£9000 is exactly six times more than I paid for our first house.I must be getting old...Graham

We're up and running again, fine tuning whenever I have time.Graham.

According to Google, everyone now uses tablets and mobile 'phones to access the site?.I'm not sure it's true but if we want people to find our site I need to 'go with the flow'So expect a few disruptions this evening whilst I update the site.All should be back to normal by Sunday evening.Graham, sit...

I was told that Norton used to bead blast the plates to pacify customers who complained of the evil take up. But the fix only lasted 500 miles or so: Only one employees comments, never had chance to confirm. Ducati are worse, they simply say; Worth reducing the load on the diaphragm by replacing the...

Just a quick PS:Yes we sometimes do have rogue posts, but there are plenty of moderators in such an open forum so the bad gets buried in seconds!G

As for the forum;I believe that everyone eventually realises that being part of something is so much more rewarding than simply taking instead of giving.Personally I never want to force anyone to contribute to the R.O.C. in a purely monetary way. It CAN and WILL survive without members who don't thi...

Yes,For £175 per face, including 20% VAT I will take your endplates to a local engineer in Leeds, between us, we have written a CNC program to machine the trochoid shape at 0.6mm depth. I will then send off a batch of endplates to be metal sprayed and machined by the company that Norton Motors relie...

Bit tired tonight but I'll sort the online renewals before weekendGraham

Hello Richard,Didn't receive a reply of any kind either.Are there strange forces at work on the R.O.C forum :-)Why do people post if they don't want to know the answer?Oh well, there's nowt as strange as folk.I don't post very often but I am pleased with the forum. Glad I started it!G

Regular batch moly coating every 3 to 4 weeks.I need to keep the numbers up to keep the price down, machining the plates is the variable but I'll hold the price regardless.£175 per face including VAT.Graham.graham@startright.co.ukAnd.. it's not a hobby! and I'm not retired

Never been an exact science for me,Leave the plugs out, put the bike in top gear, a couple of squirts from an oil can down each plug hole and turn the engine using the back wheel to spread the oil round.You can tell there's enough oil in there because it starts dripping out of the joint between the ...

In order to minimise the hesitation problems when you twist the throttle to set off, especially on Commanders. I specified a reduction in the maximum retard on 'my' (Julian Kemp did all the hard work) Ignition boxes. It often results in a slightly uneven idle, but in my opinion it's worth sacrificin...

How many have have you visited?I think it's 16 for me..http://www.wolfgang-dingeldein.de/wanke ... ab1983.htm

Hello all,Having asked many of my customers if they mind me sharing images of their rebuild, I'm pleased to find everyone seems happy to share.If there are images of your rebuild that you would like me to remove I will do so immediately, but I hope, by sharing, I can help someone.There are a lot of ...

Did you watch ITV4 tonight?Excellent report on the Classic TT and....In the background on two of the interviews I heard the wonderful noise of a rotary norton. Also caught a glimpse of Richard Wilson 110 mph lap! 21st in the F1 on a totally reliable rotary. A fantastic result for Andy Wilson who bui...

Hi Ned,Bit late to save your laptop but you originally registered in 2011: Sun Oct 23, 2011 7:19 pm as nedbonnie, not nedbonnierider :-)Good to have you back.Site Admin.

So far, the DVLA have managed to introduce new systems that do indeed improve on the old ones (AFRL for instance)BUT!!You have to be (very) computer literate and you have to trust the system.If things go wrong, the 'real human' backup is better than it used to be because most of the systems are beco...

The F1 parts book (Hand drawn by Richard) shows a DN part number DN.0314.P55.That means the RD350LC type master cylinder was modified. The modification was simply to machine Yamaha off the lid :-)Sadly, the original RD350LC master cylinder is no longer available new , you'll have to find a used one,...

Hi Wayne,I think I can stand still for a while, would that do.:-)Graham.
