Jubilee headlight size

Posted by dennis_thompson at December 05. 2017

I bought my 1965 Jubilee in bits and it has no headlight.

I bought an 'AMC' headlight shell but it looks small.

The rim is about 6" in diameter.

Before I try to find a headlamp to fit, and this seems to be a rare size, can anyone tell me what the headlight shell rim diameter should be?

Many thanks,

Dennis

Correct headlight for the Jubilee/Navigator (1961 onward) is Wipac 6 1/2". Adverts at the time said it was 7" but it definitely wasn't. The earlier Jubilee had a smaller 5 3/4" Wipac headlight.  The 6 1/2" Wipac glass lens will be hard to find unless you hit lucky.

Thanks, I think I have the 5 3/4" shell as it is not 6 1/2".

Either way it looks like I need a 7" shell because, as you say, other sizes are hard to find. There are 7" lamps in the NOC shop.

I hope the fork cover/ headlight brackets will accommodate a 7" headlight!

If you can find a 6 1/2 shell ( I need one too! ) then a metric lamp will fit. That’s what I used back in the day after I rear ended a fiat 127!

Yes the 7" Lucas will fit without any problem.  I have one fitted to a Jubilee Cafe Racer with the later 1963 style forks.  It is an all chrome shell with holes for an ammeter, two warning lights, and a Lucas flick switch for the lights; they look the part and are easily obtained as I think they are Commando but the downside is you can't fit the correct Jubilee switches and speedo.

Thanks both, I am thinking of doing the 12v upgrade so fitting the 7" shell might give me more options for bulbs and parts might be easier to obtain.

Just the small issue of where to put the speedo!

My 1961 Navigator headlamp shell has a 7" rim fitted. I assumed mine was original.  Everything just about fits  .

Well you learn something every day !.  I have never seen a headlight like that before; there is a distinct difference in size between the body of the light and the actual rim.

Your ignition switch is also the different type - is it the one with the 'key' ?

You mean this one. 100% secure,guaranteed!!

That's the one.  Yes total security; any pocket sized screwdriver will turn it on if you lose the key. !

You have also got a Lucas ammeter.  I have often wondered when they changed from the Wipac ammeter to the Lucas ?  My 1959 Jubilee has the white faced ammeter with the chrome cover and both my 1961 Navigators have the black faced Lucas ones but the parts book for 1961/62 gives the same Wipac part number for both 1959 and 1961.

I’ve not seen a shell like that before, I wonder if it’s “home” made?

Re: Jubilee headlight size

The 7" rim has been welded to the shell. Difficult to photo. This is what it looks like on the bike .

Nice bike. Where did you get the seat from?

Looks like a custom job.

Re: Jubilee headlight size

The seat is an experiment. Is it time for this lightweight to have a single seat I thought? What would it look like and how ? It uses the lightweight petrol tank as  a styling template.It is just a work in progress, still lots to do.

Hi Dan,

It's a "hand-built specialist British motorcycle"- known to most sensible people as a  'bitsa'.

The original Yamton was built (25 years ago) as a racer in the Forgotten Era class.  It had a 1959 Jubilee De Luxe frame with a Yamaha engine/six speed gearbox but it was protested against as not legal (because it was too fast! ). All the Norton bodywork was of course removed and it was fitted with a proper race seat and hand made (by me ) alloy side panels , Commando exhausts etc etc.  In recent times I refitted the original De Luxe bodywork and seat to the Yamton so all the racer stuff was surplus.  A spare De Luxe frame was obtained from NOCshop and built up into this. It still has race tyres (not for road use) fitted and the polished alloy side panels etc but the proper Jubilee engine still needs sorting. It's only to  play with and it's too cold out in the workshop - minus 10 these last few nights.

One day I will grow up and act my age but not just yet.  We still have the race Gold Star (fitted with Honda 750 front forks and disc brakes) to sort back to road use.

Patrick

I like the sound of your garage! I have a Navigator engine, (just pegging the layshaft bush) spare frame, tanks and full width Dommi wheels to rebuild, that too will be a bitsa, just got to decide whether to rob the jubilee of its roadholders, along with the model 50 engine, gearbox needing a rebuild, pre featherbed ES2 frame, long Roadholder forks and more wheels! Am tempted to sent the engine to Mike pemberton to breath on!

Sorry gone of topic, perhaps we should start a projects thread!

Roadholder forks on a Jubilee? Are the Jubilee forks that bad (still re-building mine so I have not ridden it)? And can roadholders be used on a Jubilee without modification?

Re: Jubilee headlight size

Posted by patrick_mullen at Thursday 09:10

Jubilee forks aren't all bad if they are in good condition but you can't get any spares for them - new bushes, springs etc are not available.

The Navigator is effectively the same frame as the Jubilee so Roadholder forks are easy to fit  by using the Navigator cups and cones and stop.  They are easily available but they won't come cheap.

Re: Jubilee headlight size

My jubilee came with a set of good roadholders, one of the reasons I bought it! the fork offset is a bit different on the jubilee so I used the navigator front frame member and made a spacer for the head steady. The best bit is the front brake!

I have pair of jubilee forks but they need re bushing and I don’t have a jubilee front wheel, but could probably fit a navigator/Dommi one. Or I could buy something else .... Decisions decisions!
