1960 Navigator Rebuild Part THREE

Posted by Ulrich Hoffmann at December 06. 2017

Today I got the rest of the painted parts in blue and the tank in blue/dove gray.

Perfekt paint!

Firstly I made a cosy home for he battery, I found some blue styrofoam. Has some racing history! I bought a seat base for my Commando from Joe Seifert, he used it on one of his racing bikes with the blue styrofoam on it- but not for long....

Switches, ammeter and speedo went into the lamp housing but not wired yet.

The right switch is just for decoration, I made a conversion to 12 volts and made a new simplier wiring loom.

I forgot to take the styling panel at the headstock with my. Still at the paint shop.

The tank panels will soon be on the way to Slovenia for rechroming. A friend visits his family over there for christmas and found a good an cheap chroming shop. Hopefully I get the parts back after the holidays because the bike should be on show at a motorcycle show in Friedrichshafen at the end of January.

Well done.  It is looking good.  By the way your speedometer is not the correct item for a Jubilee or Navigator.  The dial shows a figure of 1760 (cable turns per mile) and goes up to 80 miles per hour; correct speedo is 1600 turns per mile and goes up to 100 miles per hour.  So it will not show the correct speed - it will indicate a lower speed than actual so be careful in the city speed limits.

Looks like left hand drive to me ..... my ignition switch is on the other side, but which is right?!

For what it’s worth I think mine has the same speedo as that.

Did you get the front mudguard sorted?

Thanks for the hint, Patrick.

Dan, I spoke to the man who welded the indent and he said the only way to make it fit is to cut up the indent, bent it an add a stripe of metal so that the radius is bigger- which means new paint also.

I leave as it is at the moment, just for the bike show.

Don´t know if the speedo has been changed sometime.  But if Dan has also this type of speedo, mmmh??

Maybe a different drive at the rear wheel?

Re: 1960 Navigator Rebuild Part THREE

Posted by patrick_mullen at December 06. 2017

Yes there are potentially all sorts of different ratios for the rear wheel gearbox as well !.  The 'correct' one to match the 1600 speedo is a 2:1 ratio.  The 1600 speedo is quite hard to find at auto jumbles as it may be unique to the Norton lightweights (and possibly the Francis Barnett Cruiser.)

There are all sorts of different of different 'cable turn ' numbers as this Smiths speedo design was used on all sorts of Francis Barnetts, BSA Bantams, Triumph Tiger Cub, James, etc.  It is only when you start looking seriously at  the speedo face that you discover how many different versions there are.  The first part of the reference number also varies as well;  SN3153/95   1600   100MPH on both my Navigators;  the earlier 1959 Jubilees have a 80MPH speedo and it's a different SN number.

I  agree with Uli's switches;  ignition switch on the right but I doubt if it is critical unless you are VERY seriously into concours.

I had a Honda VFR400 a few years ago and the MOT man failed it because the speedo was in KmH. I had to put a sticker on the dial reading in MPH.

Will the TUV Inspector query your MPH speedo?

Damn that means mine is left hand drive!

He didn´t query it on my Commando also with mph scale, as long as GB is part of the EU it doesn´t matter...

You got to reach the switch with the left hand when the right hand holds the throttle wide open and suddenly it gets dark!

Not that speedo is much better than a chocolate fire guard, it still swings a good 10mph radius once moving! I have a new one from ebay I might try plus the ammeter is just a push fit at the moment.

Hi Dan,

That speedo looks fine to me. It is highly likely the correct one for a 1960 Jubilee.  A needle swinging about is usually a cable fault- have you tried re-routing the cable to get the bend as smooth as possible or maybe some light oil on the inner cable.

Here's the flight deck of the Yamton - the 120 mph speedo and the rev counter do work. The headlight is the standard 5 3/4" but the original 'tell tales' have been replaced by warning lights for Neutral and Oil Pressure.

Here's the one that would really suit Uli's Navigator.  It's a KmH speedo for a Navigator.

We are a bit mixed up here ; we still use MPH and miles here in the North but a few miles away in the Republic we use KmH and kilometers.

Just bought this speedo, needs dome work but has the right numbers

Re: 1960 Navigator Rebuild Part THREE

Well done.  You certainly don't hang around.  I had forgotten about the Ariel Arrow as a potential user but from now on it is a Norton Navigator speedo. Both my Navigators have this same reference number but they both have a white marker line at 30MPH.  It is amazing the differences even when they have the same reference .  They are 60mm- not 2" -and you can get the correct new chrome rim on Ebay UK.

It will keep you gainfully employed taking it apart and renovating.  You can do this over Christmas sitting by a big fire in the living room.  The first proper snow has just fallen here last night - so I'm staying away from my workshop until the Spring comes.

By the way if you do get a new rim make sure you get the 'flat' one.  There are two different profiles.

Nice work, love the blue colour, always hated dull colours on motorcycles!

Just to encourage you an amusing film on YouTube!

Patrick, where are you with that snow?

Hi John,

I'm in Co. Tyrone, Northern Ireland, about 15Kms from the (no)border with the Republic. Our vehicles here are subject to MOT (done at special Government test centres so different to the English version), or NCT if you live 10 miles away, but we all know they are very much the same as the German TUV.  (TUV here has a different political meaning !!)

Picture of my front lawn taken just now - it is still snowing and temperatures will be well minus tonight.

I fitted the front styling panel for the headstock an routed all the cables through it.

Clutchcable and chokecable through the right hole (seen on the left) and the wiring loom through the left hole.

IMG_20171208_083428

Gas cable goes through the hole top right.

IMG_20171208_083440

I can push the tank forward until it hits the panel but when I fix it with the screw at the back there is a gap  between the tank and the panel.

That does look neat and tidy.  We really need an opinion from Andy as to what is strictly correct-does anyone else know?.  My opinion is that the wiring loom through the left hand hole is correct; throttle(gas) cable through the right hand top is correct.  I have the choke cable and the wires to the horn through the bottom right.  Neither of my Navigator clutch cables were long enough to go this route and didn't allow free movement of the handlebars.  So if you are happy with the operation of the cables your routing is much better than my version.  My clutch cable just runs behind the top left hand of the styling panel but my excuse is that the clutch operates smoothly that way.

Everyone of my Jubilees/Navigators has a gap between the panel and the tank.
