Hi everyone !

Just wanted to introduce myself : Fruzz from Brussels, Belgium.

Compliments to everyone for this excellent forum; full of resources, stories and information.
Its amusing how hanging around people with likewise interests helps convince oneself that they haven't, in fact, gone completely mad... :wink:

So this is the 3rd forum I have joined. One for every type of vehicle I guess.... :oops:
Despite my relative young age, I have been exposed to the world of old cars and motorcycles ever since I was born. In truth, my father decided to cure the baby blues by buying an old (and battered) Aston which we still own today. That particular car suffered from me growing up, wetting my pants as a baby on the backseat, and throwing-up the Friday fish dinner forced down my throat by parents eager to educate their child (funnily enough, I was never obliged to eat fish after that incident...).

After a quarter century of reading classic bike magazines (there are some excellent French reviews btw), I'm now finally making a living and able to justify (or not) a brothel of two-wheeled ladies in my cramped Parisian garage. It started with a tatty Honda CB125 K5, I real POS but one that made me understand that greasy hands at work can be excused when the story behind is worthwhile : "Oh, I had to replace a spark plug and blown fuse in the middle of the Champs Elysées..."

Various small bikes followed, a CB125 single, Suzuki GT (good fun!), CB350, CB550 & CB750 Four, etc. All this whilst friends and colleagues opted for "clean" and "modern" vehicles... Which, to put it kindly, appeal as much to me as spending a day dealing with french bureaucracy...

In any case, I have just recently fell for a lovely Norton Commando. I've always had a personal affection for the Norton Motorcycle Company. Be-it pre-war ES-2's, 16H's or the cathedral mono cylinder Manx 500's of late 40's to early 60's; there's always been something exciting to me about Nortons.

I was initially looking for a 650 SS or early Fastback. But a very nice 850 Interstate Mk.3 shone its Lucas headlight my way...
Purists will obviously prefer earlier models, and I tend to agree. Someday I hope to find an original Fastback (in flake orange please, sir), but logical reasoning lead me to choose this particular model.

This lady is from 1977 and has 14.000 miles on the clock. Frame number is 850-3531***SJT with an unmatched engine number. From my understanding, this was an unfortunate recurrence during the last months / years of production (any ideas on this are welcome). Not that I really mind, but I'm always interested in historic facts while I await Mick Duckworths' book on Norton Commandos.

Purchased in England, I rode the bike back to London and had it shipped over to Paris (thank you Chas Mortimer) where I currently live and work.
It has been a rare pleasure riding it regularly and I've already clocked over 2000 miles on it. Going back to the CB750 is like drinking a Heineken after a round of Belgian beer...

So far, apart from routine maintenance and a few common glitches, I've had few problems.
- The rear braking system was in need of repair, so I cleaned and replaced all the gaskets & master cylinder. All fine now.
- The reset knob for my trip meter snapped off (my fault) so I'm planning on sending the dial to a pro this winter to get it fixed.
- An LED idiot light in the dash (orange indicator) has ceased to be, I've already found a replacement (very expensive btw!)
- The seat is an average aftermarket replica with a plastic base, I'm still looking for a good quality replacement (any help is welcome)
- And I also replaced the higher bars (seen in the photographs) with lower flat-style European bars (better suited to my riding style).
Deviations from standard are a primary belt in place of the rattling triplex chain, a Boyer Brandsen ignition and Pea-Shooters (don't like the black caps anyway).

There's also a slight leakage at the head gasket. A common problem with rarely used bikes that suddenly become almost daily rides. I'll most probably be replacing it this winter, but the seepage is only slight so its not keeping me off the road for now...

Here are a few photographs for your enjoyment !
Feel free to let your tongues loose and insult or complement me, I can take anything; I'm Belgian and without a government.

Take care & safe riding to everyone !

Welcome to the forum, fruzz02

Thanks for sharing the photos.

Are you sure you have quoted the frame number correctly? Because the very last Commando build numbers were six digit serial numbers 33653* not seven digits (3531***). Also the "SJT" stamp is unusual? Does the headstock certification plate (if it's there?) number match the six digit engine number or frame number?

I think it's more likely the engine or crankcases (or the frame?) was changed sometime after your Commando left the factory?
The gearbox should also have been stamped with the same number as the engine and frame certification plate. You would have to look under the airbox to find it.

Welcome to the forum, from a fellow Mark III owner from Texas.
 
Re: First Post : New arrival - Norton Commando Mk.3 Intersta

Thanks to all for the warm welcome! :D

L.A.B. : In response to your questions, the plate number (located under the seat) is indeed a seven digit number 850-353**** (four numbers after 353) with "SJT" at the end. This is indeed a perculiar sequence, one I had not seen before either. The engine number however is a common six digit 850-335***

Biggeof : I have actually decided to keep the bike stock and not do any further modifications. Upgraded brakes often look slightly out of place, despite their obvious superiority. I'm not fond of anything modern that can be "seen" if you know what I mean. Regarding the electric start however, I must agree that a four brush mod could be usefull, but I find the costs still too high and get along fine with the kick starter.

Josh : Thanks for the seat address !

:wink:

The plate would normally be fixed to the headstock, with an additional frame number stamped alongside it on the right hand side (the frame number would not necessarily have matched the plate/engine/gearbox number).
The 850 JPN models had their certification plate under the tank/seat, however no Mk3 JPNs were supposed to have been built, so I expect your Commando was originally serial 335*** that has probably been re-built using a replacement frame but the plate position definitely seems odd. You could check if the gearbox number matches the engine or not?
 
Re: First Post : New arrival - Norton Commando Mk.3 Intersta

L.A.B. : I'll check the number on the gearbox this week end, and the headstock for any signs of a removed plate or number.
Concerning the plate location, I can always email you a photograph if need be...

Thanks, however I doubt I can offer you any additional information.

Was this Commando an ebay purchase by any chance (from the Newcastle area perhaps)?
 
Re: First Post : New arrival - Norton Commando Mk.3 Intersta

L.A.B.: No, the bike was purchased from a privte owner living in the Kent area.
I've seen a few strange eBay.co.uk auctions with practically identical descriptions for various Mk.3 bikes, this luckily is not one of them !
 
Re: First Post : New arrival - Norton Commando Mk.3 Intersta

The NOC or Andover Norton (or member ZFD) may be able to give you more information?
Provided all the documentation was in order then there's no problem, it's just another "Commando oddity".
 
Re: First Post : New arrival - Norton Commando Mk.3 Intersta

Welcome Fruzz,

The reset knob for my trip meter snapped off (my fault) so I'm planning on sending the dial to a pro this winter to get it fixed.

With a little bit of luck you may just have pulled it out and it might just push back in.

I've had some of my auction listings copied word-for-word, and always report them to e-bay and they get pulled.

These people have no clue.

Welcome!

LED? Pretty sure it wasn't an LED or is to was it wasn't like that from the factory.
 
Re: First Post : New arrival - Norton Commando Mk.3 Intersta

With all of that said, you bike is beautiful. I have a MK III Roadster, but sometimes wish I had the Interstate tank and seat. Just keep doing what you are doing, the bike looks great.
 
Re: First Post : New arrival - Norton Commando Mk.3 Intersta

Calbigbird : Thanks, its a lovely bike. And i'm not the kind to mess around with useless mods.

Swooshdave : Idiot lights on Mk.3's are indeed a kind of LED bulb. Just adds to the general irony around the Commando design...

Cash : I've already taken a good look and tried to put it back in place. Unfortunately, its clearly snapped off just below where it's supposed to fit in.

Grandpaul : Its sad to see so many vintage bikes in the hands of complete fools !

Safe riding !
:wink:
 
Re: First Post : New arrival - Norton Commando Mk.3 Intersta

Hey there Fruzz02, super sweet looking ride, Ditto - welcome to the forum. Cj
 
Re: First Post : New arrival - Norton Commando Mk.3 Intersta

Hello again Fruzz02, i think the front brake mod that he was talking about , is to the master cylinder. The bore is too big and needs to be re-sleeved down to 13mm in order to get the pressure up from the brake lever to the caliper and improve braking. Cj

The original Mk3 P&K warning lights certainly do not contain any kind of LED bulb, and they can be repaired easily and cheaply using a small capless bulb without paying Norvil's vastly inflated prices.

Riding most other bikes after the Norton, is like being forced to have sex with a condom after enjoying the real thing.
