Re: Commander rear brake disc

You're unlikely to find a new genuine Yamaha vented disc now, but there are a few used ones on eBay, mostly listed as XJ900 pre-Diversion.
Lot's of replacement new solid discs though.

Re: Starting up procedure

Hi Jannes, With the engine running, the only time the oil pump doesn't turn (IP2/Classic/Commander) is when the bike is stationary, gear engaged, and clutch lifted. That's because the pump is driven by the end of the gearbox input shaft. I don't believe any damage can occur during those brief moment...

Re: Parts general

Hi Jannes, The lenses, and possibly the bulb holders, were made by English company L E Perei; lenses had all the correct 'E' approvals. I don't know if they were made specifically for Norton. When I enquired a few years ago, they said they no longer had the mould tooling and couldn't make any more. ...

Re: Parts general

There really is a connection between the Classic rear light and the Aston Martin Lagonda. Norton's own in-house designer, Mick Ofield, did the styling for the '1000'- series rotary, often referred to as the Aurora or Cooke Nielsen. which almost made it into series production. A car stylist, William ...

Re: Registration-number

Jannes, UK vehicle registration series have changed several times over the years. The oldest system was six, or less, characters such a LG9899, my first car and AUJ800, my first bike. Then to promote annual sales, the manufacturers requested a year code resulting in GWD607D, a 1966 T100, my first ne...

Re: Registration-number

Jannes, In the UK, the original registration number is related to the year of first registration and the area where it was first registered. After that, the owner can ask for a different number which may mean something to him personally (such as JPS 588 for an F1) or, if following the year/area seri...

Re: Handle Bar Switches

Hi Jannes,
Original Classic's bars were made to a Norton design.
I had new bars for my Classic replica from a Yamaha RD250LC, available in black paint or chrome.
They were a little higher than the original, a little more comfortable for me.

Re: Commander Hot rear brake

Odd how the Brembo master cylinders of the IP2 and Classic never seemed to suffer the same blockage, but the Yamaha ones do.
Maybe the feed hole in the Yamaha items is smaller than the Brembo.

Re: Commander Hot rear brake

It's always the master cylinder's fault! Or, more correctly, the owner's fault for not changing the brake fluid frequently enough. Old fluid congeals to a sort of wax in the bottom of the reservoir or, in the case of the rear brake, in the black plastic elbow connecting the cylinder to the reservoir...

Re: Charging issue - high revs equal low volts??

Mark,
If you've got a Sparkrite ignition unit with a single yellow wire not connected to anything, or a MiniMag ignition, and a deep pocket, Andover have stock of the later Motometer, part no. 55.0569.
If you haven't got either of those ignitions, you're stuck with the old Veglia.

Hi Mark, Tacho wired into the alternator means it's either a Veglia (says 'Made in France' on the face), or the Motometer replacement ('Made in Germany'). Early examples of the latter, with a round terminal block on the back, were prone to the sort of needle flutter you're seeing. Later ones have a ...

Re: Boyer ignition

The Boyer has all it's gubbins potted in a polyurethane compound, making access very difficult.

Re: Steering Lock

Mick,
Turn the key, clockwise I think, and push it in whilst wiggling the bars on full left lock.
After the lock has engaged with a slot in the steering stem, remove the key.

To unlock, insert the key and turn anti-clockwise, allowing the spring to push the lock body out again.
