Hi, can anyone tell me if the 1972 Interpol frame is the same as the Interstate frame? Due to arthritis, I'm planning on converting my 750 JPN replica to an interstate, with an easier riding position. The JPN replica started off as an Interpol way back. Basically, I need to know if the Interstate  seat and fuel tank will fit properly.Thankyou for your help.

Laydown gearbox 53 Model 7

Forums

Canada calling. I have finished restoring a '53 Model 7 and an odd oil leak has cropped up. Oil is leaking through the steel kick start sleeve and the inner cover of the gearbox. I have checked thoroughly and it is no leaking through the kick start and the steel sleeve itself. I have check the Andover Norton laydown gearbox drawing and there is an item #79 shown but not listed as Andover do not make this item. Firstly has anyone out there experienced this leakage, and second is item 79 a seal, shim etc. Any thoughts would be appreciated.

SS Camshaft ?

Forums

My Dommi 88 is fitted with an SS Camshaft ( marked T2219@3 ) it seems. Does this require Pushrods and Valve springs as used on the 650 SS and Atlas models to be fitted ? I came accross this advice in the Haynes Manual (chapter 1 -22 ) . My Cam is with Newmans being inspected for possible re-profiling and I now have 4 NOS Cam followers thanks to NOC members and the NOC shop. Thanks , Wayne.

 

rear brake plate

Forums

I bought a rear brake plate for my Norton 650ss - advertised as Dommie plate but the brake shoe pivots have wire circlips instead of retaining plate/tab washer and bolts.

I assume it's an earlier plate from ES2 or very early twin.

Does anyone have any knowledge/experience of these plates, please?

Thanks

Navigator Spark Plug Recommendations

Forums

Afternoon All,

I've just had my Navigator rewired to 12v with a Pazon electronic ignition.  I can't recall how old or what type the existing plugs are so will treat myself to a shiny new pair.  Question is what type would be best suited to the new setup?  The carb is stock.

I see elsewhere on the site that the original plug was either NGK B7ES or Champion N4. Would these still be 'right' for my rewired bike or is some change recommended?  Thoughts please!

Regards,

Anti Scottish? Or just living in the Twilight Zone?

Emailed Eddysmototadcaster regarding a '57 99.

"We can't finance anything older than 1968."

OK.

Phoned about financing another bike. Asked me where I was based.

"Scotland"

"Sorry, they don't finance motorcycles now."

Sat in my workmates van and got him to call about financing a bike.

Scottish also.

"I'd like to finance this bike."

"Let me speak to my boss"

We can't finance anything older than 1980"

Can anyone tell me what the hell is going on?

Electra cylinder head machining

Forums

Having got my Electra heads back from vapour blasting a close inspection reveals a potentially serious issue with the way the face of the right head is machined either at manufacture or by someone skimming the head in the past.  The attached photos show that the left hand head still has most of the lands round the combustion chamber and the push rod tunnels.   However, the righ hand head has been machined almost completely flush to the fins removing the lands around the push rod tunnels.   A careful check with a steel rule shows the face is flat and even so there is no sign of warping.

oil filter and chain adjust

Forums

This is regard to my previous topic "Chain Adjustment". So I received the correct aligning [dowel] bolt for the rear wheel to brake hub and believe it or not everything now lines up far happier although still displaced towards the timing side.

Continue to rebuild I would like comments on fitting the detachable oil filter I bought from RGM, does it fit into the feed to the engine?

Many thanks again to those who helped with my "chain Adjustment" topic

 

 

 

 

 

 

 

 

Double drum front brake.

Forums

Hello Norton people. This is my first post so here goes. From my investigations, I understand that my frame is from a 1956 Dominator. It’s a Triton I bought for £300 some (cough) 40 years ago. My query relates to the current front hub/brake arrangement which comprises two 8” drums bolted back to back and fitted with two brake plates. The brake plates (both SLS), shoes, bearings, distance tube etc appear to be standard Norton components.

Rear Isolastic Adjuster incorrectly fitted

Forums

I have just noticed that a previous owner had upgraded my ‘72 Roadster to adjustable isolastic mounts and that the rear adjuster has been installed on the wrong side (so that both front and rear adjusters are on the engine timing case side of the bike).  Can anyone please tell me whether or not this is likely to be a problem or whether I should go to the effort of swapping the rear mount around?

 

Regards to all

 

Front styling cover, Navigator/Jubilee

Forums

The piece of sheet steel wrapped around the steering head, (aka headlug cover?), on a standard Navigator/Jubilee.

There seems to be provision for three bolts fixing it in place, one facing forward and two facing sideways, just below the top steering bearing.  Are there any spacers involved in mounting?

A photo would be very helpful showing just how the cover fits.

One final question, should there be a rubber edging on the cover where it faces the tank?

Hogslayer

NOCcer Fans of 1/4 mile racing will be delighted to hear that Hogslayer, the twin-engined Norton raced so successfully by Tom "TC" Christenson back in the 70's will again be pounding the asphalt at Santa Pod this summer.

According to Visordown, the bike is to be awakened from it's slumber at the NMM and prepared to race again at the Dragstalgia event there from Friday the 5th to Sunday the 7th of July 2024.

Clutch Question

Forums

1948 ES2... Just replaced the cage and rollers in my clutch as the old one was so worn the rollers were falling out.

When I tighten the backing plate nuts the rollers lock up. I have double checked the components and all seems correct.

My only thought is the backing plate might be slightly warped but would appreciate any comments.

Thanks

 

Electra Head & Cylinder Base Gasket

Forums

After a productive day stripping and checking the Electra's heads and barrels I am ready to get them vapour blasted before having the cam follower guides and valve guides replaced.   

Having checked the NOC shop and noted they now have base gaskets in stock I noticed the part number is the same for the late Navigator and Electra.   Having an early spigotted copper and aspestos Navigator head gasket and a base gasket in stock I checked both for fit......and was surprised that they both fit the Electra perfectly!   

3 start and 6 start oil pumps ?

Forums

Despite reading everything I could I cant find any real descriptions or photos as to what they actually are or look like. I realise one pumps more oil and can do more harm than good but how do I know what has been fitted to my 59 ` Dommi 88 ? Do I have to remove the worm gear to check and clean the pump if so any advice on how to do that ?

Dommi 88 cam followers ?

Forums

One of my Cam followers is badly worn /out of shape where the Push Rod fits. Mine are chamfered back and front and appear to identify as a standard `Flat foot` according to the photos of identification in my Dominator service notes V1.2 manual. I thought I had found a set on the NOC shop but they dont have the chamfers back and front. My question is can I mix and match using the chamfered good ones on one side and the NOC shop non chamfered ones on the other ? Andover Norton have them on their site but ONE PAIR works out at over £300 ( non chamfered flat foot ).

Indicator problem

Forums

I have fitted direction indicators to my Navigator.  A set of "universal fitting" indicators, I fitted LED's rather than use the filament bulbs.  A 3 pin flasher.  The switch is a combined indicator, horn and high low handlebar mounted unit.

I fitted them, powered up and all was well.

The problem is that when I run the engine the flashing becomes very erratic.  Clearly some interference from somewhere. I'm using Boyer electronic ignition.

Gearbox.

Forums

Here's a puzzle. With the bike on the work bench, engine not running, I can select from 1st gear to 3rd up and down as I wish with out a problem but go from 3rd to 4th and it gets stuck in 4th. Remove the outer cover and I can lever the quadrant to change down to 1st. If I set the ratchet spring I can then select from 1st to 4th to 1st to 4th several times until it gets stuck in 4th. The gearbox works fine on the road - no problems. I've tried fitting a new ratchet spring from Andover but with the same result. Any ideas appreciated.
