Hi,started to put my Jubilee frame together.Can anyone tell me the distance between the rear welded on tubes just in front of the rear shock mount.Also does the swingarm pivot on the frame or should a washer fit between frame and swingarm and finally does the Navigator/Electra have an extra support for the steering head,if so could someone give details on how it fits/where it fits etc.Any advice is much appreciated.

Thanks Dave.

What exactly are you proposing to do ? There is a spacer tube bolted into position at this point with a long stud/nuts/washers to hold the frame securely together. This spacer tube is also the rear mounting for the tool box on the De Luxe. Do you not have the proper item? I think NOC spares has these long frame studs; not sure about the spacer assembly. The Standard version is slightly different to the De Luxe.

The swinging arm should be a snug fit between the frame and the central channel section. There are brass bushes/spacers in the channel section.

The Navigator is the same fitting as the Jubilee at the steering head and the front down tube is a straight swop for the Jubilee item-only the Electra has extra plates. Why do you need these if you don't intend to fit Roadholder forks?.

The front tubes are not quite a straight swap between the Jub and Navi Patrick, the Navi head steady is in a different place and the steering head angle is slightly different to accommodate the different offset of the roadholder forks. I believe the Electra front tube is reinforced/braced but not sure where?

Hi Patrick and Dan.I am building the jubilee from a box of parts,some things I can sort out some I need a little help with. I have a stud for the rear frame but not sure of the distance for the spacer(I have tubing I can use) it also has a Deluxe oil tank but the frame is a standard Jubilee.The question about the steering head is because I am fitting modern forks(not roadholders) and I thought the bigger lightweights had a head support.Because I am building it from a box of parts and have a mix of models I have given up on originality but I will be happy with my self assembly Jubilee.

Hello Dave,

I make the spacer tube 144mm in length and the same outer diameter as the bits welded to the frame. ( It is a bit difficult to be absolutely precise because all are already painted or powdercoated and fixed in position - so I could be a mm or so out). The Standard one is a plain spacer tube; the De Luxe has a fixing welded to it for fixing the tool tray which you won't need.

Remember if you use the De Luxe oil tank you have to remove the seat to check the oil - easy enough on the De Luxe as it has a quick removal seat (well sort of) but the Standard seat is bolted down so you need spanners for this. You will find it a lot easier to use the Standard oil tank or I suppose you could modify the standard seat somehow.

As you are fitting modern forks you will have to make modifications of some kind to the steering head to get these to fit/correct steering angle etc so that's the time to make any other alterations to the head; all in the one package so to speak.

Hi Patrick,thank's for the spacer size just checked the distance I have and it looks like the frame has sprung out slightly.Will make a spacer and get on with the trial build up.I will check the head angle/steering as I get further into the build.

Itâs a shame you canât slide newer stanchions into the jubilee yokes that would keep the angles the same. Mind you the jubilee isnât the fastest bike on the block so I doubt it would be very sensitive to minor changes!

Hi Dan, I agree about the yokes on the Jubilee,Norton probably din't expect any to survive this long and also it was a budget bike to start with.At one stage I considered putting some Greeves forks in the Jubilee yokes but the fork's I am using came along at the right price.

Dave.
