Having a spare moment, thought I'd search for alternate ways of posting large images in a text.Trying the " . Add image to a post " clicky, I got 'site not available' but searching deeper, learned that imageposter.com has been replaced by imageshack.us.If the forum link is amended to this...

When the sponsorship for the JPS race team by Imperial Tobacco was drawing to an end, Norton started looking for alternate sources of income.Gulf oils had supported the JPN Commando-based team in the 70's so an approach was made to them. As a 'visual aid', one of the development Sports was repainte...

I recall that Show well ! The Commander was the first mock-up produced from Seymour Powell's clay model, converted into glass fibre by Mitchenall's and delivered to the NEC straight from final titivating at SP's. As a mock-up, there was nothing much under the bodywork, a fact noted by a group of We...

"What you need is a box of the correct ......" but of course, with the engine already out, what's the correct height ??????The GFB (Genuine Factory Box) is 11" high and measures 12" x 9" in plan view.R.

quote="gripper" I managed to get the starter motor off prior to removing the engine and a ratchet strop over the frame and hooked onto the ends of the main shaft saved the wife from having to throw herself under a falling engine while she assisted. What you need is a box of the correct hei...

Roger, Piece of wee! No problem- provided of course that it's less than 256k and 800 x 800 ! Which rules out almost everything except a big avatar. Gregoria.jpg Since most of my snaps are upwards of 1Mb, I have to reduce them to place them here, or put them in the Gallery and refer across.Unless som...

Saddened to report that Tom Wheatcroft died yesterday after a long illness.He revived the Donington circuit some thirty years ago and established the museum of F1 cars there.I recall seeing, in the late 80's, a V16 BRM having new fuel and oil tanks being made at an alloy craftsman's workshop. When a...

For a peaceful life, you've sometimes got to spend the pension on things other than the bike or the boat. So, I am instructed by 'er indoors to dispose of our lounge and dining room furniture even though it's almost perfect and only twenty years old. All by William Lawrence, Faversham style, and var...

quote="Malc"Looked at the oil pump pics.3 outlet, I am about 95% sure is Kawasaki triples.4 outlet large is the same as I have which I was told was RG 500 and has Suzuki part no with it which I think is the original packaging. Thanks for the identification. 4 outlet small, I would guess at...

In addition to two types of 4-outlet pump, I found a single output pump and a three outlet one also.I failed miserably to attach photos to this reply, but you'll find a picture of each type in Members Gallery.1M Pump is the single feed, fixed output, Mikuni pump fitted to the Norton 731 drone engin...

I sorted through my 'pump' drawer today and found four 4-outlet pumps that will fit a Norton and one bigger 4-outlet in a Suzuki box marked 'GT750'. Unfortunately, my camera was not to hand but I'll try again tomorrow.I had always believed that the 4-outlet pump was for a 3-cylinder/4-bearing crank...

Another 'just-after-pressing-submit' thought.Some the NRS588 (or was it RCW588) race bikes had an auxiliary feed direct to the rotor bearings by means of a spark-eroded oilway along each end of the eccentric shaft. These used the four outlet pump, main feed going to the main bearings as usual and s...

quote="steve traynor"has any body tried or has knowledge of using a four outlet oul pump(rg 500) instead of premixing when using an ejector exhaust to lube rotor tips and bearings The pump to use is one fitted on the early type fan-cooled twin-rotor aero engines made by Norton and then Mid...

quote="johnbirchjar"I fitted new filters,and perhaps I "dressed"them with to much oil, but would'nt the exess oil be sucked into the engine? Hi John,Been there, done that ! The first one I did many years ago dribbled for months and stained the engine.You only need a small amount ...

quote="Wayne" Richard if I pm you with the frame number would you be able to provide any information.Wayne, Peter at Rugeley has the record books and will, I'm sure, oblige with the information.R.

quote="gripper" 1. On the RH induction pipe between carb and engine there are two tappings that are currently linked by a piece of tube. I presume that this was part of the previous single rotor idle system. (mine is post that system) can I block these two tappings and do away with the tub...

After setting up UAV Engines in 1991, Managing Director David Garside was approached by an individual who wanted to buy a 38bhp single rotor engine for a paramotor application. Paramotors, for those unfamiliar, are basically paragliders with an engine/propellor strapped on your back. Never one to m...

quote="andygbsmith"Hi is this anything to do with Nova transmissions? Andy Nova Racing is a German company set up to develop the single rotor engine for kart racing. It is similar to the Norton/Mid-West/Diamond engine and some minor parts are interchangeable. However, all the main componen...

quote="Interpol2471"I wouldn't hold your breath..... Come on Richard have you called yet You may think that, but of course I couldn't possibly say !I did, however, meet a man recently who was less than complimentary about the garlic operation. R.

I went to a kart race meeting near Grantham ten days ago just to see these engines racing. Although all the engines are sealed by the UK distributor and allegedly all the same spec, some seem to accelerate better out of corners than others.Max engine speed is either 10,400 with cast iron apex seals...

Hi Tig,Nice to hear from you again !Glad you like your Commander - how many miles since the rebuild ?Alloy rads are next on my own list; I made the mistake of trying to wash mud & flies out of my standard rad with a hosepipe - and washed the vanes out as well red face .For when you get your F1 ...

I presume the bike I now have was one of the promotional bikes, at least I hope it was wink and it does still seem to have the leg-protector mouldings on the fairing, but I believe the supporting frame was removed to make servicing a little easier. Hi Mike,Yours was certainly one of the demonstrator...

quote="andygbsmith"The only negative is when you turn the light on it takes about 15 seconds to get up to full power, Does that mean you don't get much light when you press headlamp 'flash' as a warning or invitation to another driver when running on daylights only ? I run my Commander wit...

As it was along time ago, I think there were two 'nice' working promotional bikes and six 'crashers'.The latter were built from production rejects and rebuilt over and over again by John McLaren and Reg Painter at the workshop in Hampshire. For Norton, a very profitable business as John & Reg a...

Hi Antony,Not recent, but I talked to him at Applecross at the end of June, riding an MZ1000.Said he was busy rebuilding a house up at Wick (I think).Richard.

As is always the way, press 'Submit' and immediately think of another idea on the subject.Does it make any difference if you lean the bike to the left or right ?A worn gear selector fork can allow a gear to move sideways until the faces of the engagement dogs just touch each other and make a rattli...
