Hi Dave,
Confirming receipt of your payment, thank you.
You don,t want a 4", and pillar drill, a press, or a classy multi-meter, all at bargain prices

R.

All gone now. Thanks Dave.

Hi Dave, Long time no see! I'm home both Saturday and Sunday if you want to phone. I've got a few other odds and ends, including a Classic r/h plate in good condition, but several broken fins at the lower edge. A decent alloy welder could repair it. Also a pair of 8.6 rotors, both with wear marks fr...

Now I have fully retired, the following are available FREE OF CHARGE, but must be collected from Louth in Lincolnshire. Texaco 85W-140 oil, about 15litres. The correct gearbox oil for IP2, Classic, and Commander. Silkolene Classic 2T premix, about 3 litres, the preferred engine oil for all Norton ro...

'Morning All, The rear lamp assembly, and many other plastic parts of the Classic, were originally designed for an early prototype that got cancelled after 14 or so were part-assembled. I don't believe that any of the tooling remains although, oddly enough, the IP2 also used some of those plastic pa...

Hi Mick,
As an infrequent reader of this forum, did you find a replacement housing?
If not, I have one now surplus to my needs. Overhauled, powder-coated, and ready to assemble.
R.

Go to Marktplaats.NL and search for Norton Commander and you will find the bike. It's from Portugal with now a Dutch Registration. There is mentioning of an S behind the enginenumber? This should be very special? I never seen or heard about this... Perhaps Richard knows? Jannes 'Morning All, The 'S...

I agree with Tony's suggestion to dismantle and clean the sprag of any oil sludge. And while you're in there, scrub any sludge off the clutch plates and out of the splines in the clutch drum. You'll get a much nicer clutch with less of a 'clunk' when engaging 1st gear. Finally, when replacing the sp...

Phillip, My experience of this problem is more often associated with the condition of layshaft 1st gear and its associated drive dog. Corners of the engagement slots and dogs of these two parts become rounded such that heavy loads force the two apart, producing the slipping you've noticed. Occasiona...

Just to keep the record straight, very early IP2 silencers were black chrome. As a cost reduction, later IP2's, all Classics and all Commanders were fitted with the same silencers but with a sprayed black PTFE finish. That finish survived all but the hardest riders, except at the front cone section ...

Hi, The main difference is that the FZ750 output shaft is shorter than the F1. A better gear set would have been that from a later FZR750R which has the same output shaft length as the F1. I did several such FZ750 conversions using a one-off offset sprocket, dispensing with the standard oil seal spa...

Roy,
That in the black plastic containers looks to be the correct stuff, just more than ten years old and before Silkolene marketing screwed around with the brand names. I wouldn't hesitate to use it.
R.

Take care with Silkolene oils for rotaries as the name of that oil changed several years ago when they wished to use the 'Comp' brand for a range of four stroke oils.
Their rotary oil is now known as Classic 2T Premix, comes only in a metal 4 litre can, and is reddish-brown in colour.
R.

don't worry about the pannier/radio box alignment - and a bead of rtv between then will stop rainwater getting in. Panniers and suspension units are somewhat 'adjacent', corrected by the lower brackets on the lifting handles. The three holes in the seat base had moulded hard rubber mushrooms, fixed ...

No, I meant the triangular bracket you haven't got. They should point towards the front of the bike and not as I've sketched it.

Thanks, but I'm pretty sure I drew the hinge arm bracket back-to-front.
Parts Lists for the F1 and F1 Sport are like that throughout - no cash for a professional illustrator.

Five minutes searching the AN stock list:-

92.2360 Hinge bracket l/h £5.92 + VAT
92.2361 Hinge bracket r/h £5.92 + VAT

There wasn't published parts list for the P52, just my hand-written one used by purchasing and assembly. I doubt there are any copies remaining.

Despite opinions above, the flat triangular plates are ( or were) bolted to the frame with M6 screws and Avdel inserts in the frame. All Commander, P52 and 53, have those holes and inserts.
I don't have a P52 parts list so can't tell you the part number of the plate to check whether AN have stock.
R.

Trev,
There should be an O-ring cord sitting in the groove in the primary cover. Leave the gap at the 12 o'clock position.
The round cover has a tapered outside which compresses the O-ring as the four screws are tightened.
R.

I don't recall the Dzus part numbers. Try to find the correct ones on eBay or search the catalogue.

The fasteners are Dzus 'Panex' ; lots on eBay or the distributor is Southco.

All SU parts now sold.
R.

Pardon me, I've just woken up!
The threaded end of the spindle, and the washer, are both 14 mm so it would be difficult for the washer to be fitted to the 'wrong' side of the fork leg where the spindle is, I believe, 15 mm.
R.

Hi Trev, It doesn't really matter which way the spindle goes into the forks and the washer is always under the nut. The Parts Catalogue, copied from the Yamaha original, shows the spindle going in from the near-side. I find it easier to assemble the wheel single-handed by fitting the spindle from th...

My slide needles are biased to the engine, Richards 'new old stock' are biased to the engine and yet my Police IP2 Workshop Manual says to "ensure that the needle guide gives the needle bias in the direction of the rear of the machine". John. Thanks for that, John. The Norton carburettor ...

Paul, The original covered Brembo switch with blade terminals is nothing but a PITA for those who ride their bikes. Road dirt, salt, and water fin their way inside to cause corrosion of the terminals and the rubber diaphragm inside the switch slowly hardens, needing more & more pressure on the p...

I'm hoping someone might give us the definitive reply on which allows the greater fuel flow - central or biased.
C'mon Clive, surely you must know more than a little about fluid dynamics?
R.

In a previous thread "Slide Needle Removal", the subject diverged into a discussion about bias of the needle, something that I hadn't given much thought to previously. To confirm which way needles are biased in Norton carburettors, I stripped a NOS carb made by SU around 1989 to confirm. T...
