Hi all, im trying to restore a 69-70 roadster. A previous owner has changed the fork ears to after market ones and i would like to change them to the originals if i can find them but im not sure of the type im actually specifically trying to find? I know the 69-70 models have different fork ears on them to the later models but when i look at phots of fastbacks of 69-70 i can see the fork ears holding the headlights on just like on later models BUT when i look at photos of roadster and S types of the same year i cannot see the fork ears it appears like its just a straight down tube and i cant see how the headlight is mounted??????? Im confused and i cant find any info anywhere on it or close up pics...

Thanks heaps
Adam
 
Thanks so much Tim i love these forums! So did all 69 and 70 model roadster have a halo aswell as the S types? and the halo is actually connected via other small supports to the upper and lower yoke? how did u go sourcing the parts that attach the halo to the yokes?

Thanks heaps
 
Adam,

I believe the 70 roadster had headlamp mounting just like the S and R I think. There is a fellow working on a 70 roadster now and has recent posts on his bike and it has the halo. If you want to use the halo, the lower fork tree will have to be made for the halo. Look at some of the recent posts in my thread on '69 Phoenix rises again'. There are pictures of that special stud in the bottom tree that holds the bottom of the halo on and also acts as the pinch bolt for the stanchions. If you need pictures, I can supply all you will need. You will never find those stepped nuts and little white bumpers, you will have to make them.

I think starting in 71 the center steering rod was attached to the top tree instead of the bottom one like the 69/70 also.

The early Roadsters were basically low-pipe "S" models, and except for the exhaust system, they were two practically identical models.

However the "R" was more of a 20M3 Fastback, fitted with the same style tank as the S, but still had the points housing behind the barrels, tach drive off the end of the camshaft, early Fastback (Atlas) style exhaust system, Fastback oil tank and panels, so as far as I know, an R model would usually have had the Fastback headlamp ears but, as we have learnt before with Nortons there can often be the odd exeption to the rule.

LondonMark is doing a 70 roadster and possm is doing a 70 'S'. You might want to check their threads too.

The headlamp mounting ring and brackets are available as a package from RGM Motors and other companies, the studs are available from Norvil Motorcycles - probably also from others, unfortunately I am abroad at the moment or I would be able to give the appropriate part numbers.
 
Thanks so much ive just emailed RGM and awaiting reply and il try to find out from Norvil too, het Dave when ur back if u have time could u post the part numbers so im sure im getting the right parts, thanks heaps.

I went out and looked at the upper and lower yokes last night and i can see the threaded holes/mounts in both where they locate. Also as i have had the wrong fork ears on it and i want to change them back to original with no ears what part are these called? and who would i try to source these from?

Thanks heaps

Adam,
If you want part numbers I have the 69-70 spares book. Here ya go.

headlamp support (ring) 061239
headlamp stay left 061238 (left bracket)
headlamp stay right 061245
headlamp spacer 061234 (the spacer between the shell and the ring)
headlamp bolt 061356 (this is a 5/16-26 CEI on the original shell, if you have an Emgo shell you need a 5/16-24 UNF)
pinch stud 061136 (the one that is a 7/16-20 stud with a 1/4-28 extension for the ring mount.

Could you explain what you mean by fork 'ears', I am not sure what you are talking about there. The lower fork mount must have the pinch stud that has a hole out the front for the 1/4-28 extension.

Walridge in Ontario, CA has the complete ring and stay assembly for about $90USD, at least they used to. The fork stud I have only found at Fair Spares in USA for $20USD each. Luckily mine were fine.
 
Adam,
Here is how the whole assembly looks loosely mounted without the shell. There are 2 little white plastic bumpers that mount on the lower 2 mounting nuts that I didn't put on.

hey Dave that was so much help thanks heaps, u explained it perfectly and the pics were great. I was also wondering was ur halo setup an original or aftermarket cause someone has mentioned in another post they got an aftermarket one that ended up being a different size?

Im gonna do some more emailing and try and track down all the parts i need, thanks for the part numbers to.
Yeh if u look on 71 or later models the fork ears i was refering to were the bits inbetween the upper and lower yokes that hold the headlight on, take a look at a photo of a later model and youl know what i mean.
 
I just got an email back from RGM and they told me the only bike with the halo setup was the S type not the roadster????????????

now im confused :roll:

Dave, did you buy the Halo from Waldrige or is yours an original one? I ask because zotz (1970-roadster-references-and-detail-pictures-t5389.html#p50029) told me that the aftermarket part he bought was too big etc.

I got a halo from Norvil and it is the same size (except round ) as the 'original' one than came with the bike.

As far as the S model and the Roadster, they both use the same part number 06-1239 for the headlight support (halo), according to my parts book. What do those guys in England know about Nortons anyway...

ive been scouring the internet for photos of 1970 roadsters and half have the fork ear style and half have the other halo style i wish there were a way to find out what came out genuine original?

Norton model year starts in August so a 1970 registered bike may already belong to the 1971 specification. Check your VIN, mine is 1370xy (don't remember exactly) and according to Joe Seifert of Norton Motors it was shipped in May 1970.

If the upper yoke of your bike has threaded inserts on the underside then most likely it was equipped with a halo. The 1971 model has completely different yokes.

That's easily falsified by looking at the 1970 sales brochure http://www.classicbike.biz/Norton/Broch ... Norton.pdf That is a roadster and it has the low pipes.

You should definitely check your VIN and maybe even get it dated by the NOC. The records aren't 100% perfect but the three bikes I bought recently all were in and I have a shipping date on all of them.

Once you know what you have you should get the corresponding parts list. Unfortunately there are no drawings in the 1969-70 supplement so if you really have a 1970 Roadster you'll still need a bit of detectives work but thanks to Dave's excellent documentation of his 1969 750S most special bits can be identified here.

The 1971 model year was very different so have a look at the oil tank as well: The 750S and the early roadster have a completely different oil tank which is a square box with rounded edges and a corresponding different oil tank and battery carrier which mounts the battery laterally rather than longitudinally, Dave took pictures so you can find them in one of the two threads already posted here.

Its definately 69-70 although i should confirm via frame numbers, the centre stand is located on the frame not the rear swing arm and the 2 steering stop lugs are in the position of the old frame, later models just have the centre one lug.

Thanks for showing the link to the brochure as it does show a roadster with the halo on there! I will get numbers to confirm.

I will have to take some pics and post i think will be easier so u guys can see.

Thanks heaps

That is my original halo and brackets. It measures 8 1/4" center to center diameter. Here's a picture of that special nut and the plastic bumper on the bottom mount. The nut has grooves in it to catch a rim on the inside of the bumper. As you can see, my bumper has seen better days. You will never find those parts, but you could make something up.

Fork Ears on Early Roadster?


Probably sometime in the late 70's they started producing the 'eared' headlamp mounts and changed the fork mounting, so an 70 Roadster could probably be either headlamp type. I have an old list I found somewhere years ago (home.cfl.com/limeland/norton.html but it does not exist any more) and it lists the last 'S' as June 1970 #135088. Mine is 132031 and the GB, Frame and engine all match.

You might want to look at the left side 1/2" iso nut at the top of the Z plate. Usually that nut will be worn on one side from the 'S' exhausts banging on it and wearing a flat on it, at least I have seen it on a couple of bikes, that would never happen to a Roadster.
