Nortons - General

Did Norton increase the width of the rear number plate when 7 digit numbers were introduced in 1963?  
My bike has a seven digit number squeezed onto a 6 digit plate, the first number and the "A" hang over the edge of the plate!

Hi all,

Newbie here, I have just joined! 

I've recently been in touch with a very helpful technical guy at Goodyear Tyres, who now own the Avon brand, along with Sumitomo.

Last weekend, a strange noise occurred when I closed the throttle of my Model 50. It was a strange whining/rubbing noise. Like something was spinning on an axle or grinding against something.

Losses at Norton Motorcycles have passed the £100m mark since it was rescued out of administration five years ago.

Hi guys
With the take over of Avon tyres by Goodyear, Roadrider tyres in 100/90 × 19" are getting hard to find.

After finally getting my rebuilt engine run in, its time to concentrate on the fine tuning.

OK So I've got seen 4th gear layshaft cog with number 5 and number 6. Both SEEM to be similar.
Anyone tell me the difference?
Cheers
Paul

I'm looking for opinions and or advice from the Norton sages.....but I have to be honest and admit this is not a Norton query but thought tyres and rims are pretty universal.
