Hello everyone,
I'm new to the forum, I've recently acquired my father's Norton Commando 750 Fastback, This bike has been in the family years, and my goal is to bring it back to life and do it justice.
I'm very new to classic restoration but have a sound knowledge of mechanics, I'm planning to completely dismantle and rebuild everything as the bike has sat for 15+ years, I haven't found much video/photographic documentation of a rebuild of this level so will be grateful if you know of any to steer me to it.
I look forward to documenting my own progress and sharing and learning as I progress.
Cheers
Karl

If it were me, I'd try to put it together first, doing the minimum to make it go, and ride it. Then you'll 1) know whether you have all the bits and 2) learn about the bike.
Everyone slags off the Haynes manual but I think it's pretty good and features your model.

I'm fortunate to have the workshop manual and parts manual for the bike, I will still need to buy a new fuel tank and carbs as normal petrol has eaten in to them, but might be worth doing first to get running.

I've not heard of this manual before so will look it up, thank you for the recommendation.

With Stan on this
Get it built back together, run it and evaluate the level of wear, any sound tank will do for this. I rebuilt a mk2a a few years back and found it to be a very neat machine to strip and rebuild. But if it ain't broke..... drive train that is tested and found to be in good order will save you a huge chunk of time and money. Enjoy it!

I know it was last rebuilt in 1992 and sadly due to me and my brothers my father didn't get much time to ride it, so apart from a service and new fueling it may well run well.

Electrics.....
Electrics is the last thing to fully complete on any rebuild. All the electrical bits need to be in place before worrying about the loom/wiring, after all the coloured string just joins all the bits up. And you can't wire up bits that are not in place. But if you are going to run the bike for a while and you have points and the advance/retard is shot then the ignition will possible be all over the place. So you might just have to buy a new electronic ignition just to get it usable.
Battery charging is not crucial as you have at least 50 miles or up to 100 on a well charged battery. When/if you get to this point then a direct contact on your specifics ideas/problems is advised.

Thank you for the info, I will be purchasing a new battery and keep the rides local while I check its reliability.

Agree with Jan
I would start with Norman White's excellent book. I can also recommend a series of YouTube videos by an American contributor called " The Mighty Garage". He rebuilt a Mk2 Commando which I found very useful.

Brilliant, Normans book has been recommended by a few so ill buy it, thank you for the youtube recommendation too, I start watching the videos this week to get a idea of whats to come.

Ive found it hard to find information and seems like Norton like to change things alot, ill be making sure to document where everything is currently ready for when it all goes back in.

Electrics
I rewired my 1971 750 Fastback from scratch, so if you need I could send some photos showing where everything goes. I would recommend replacing the regulator/rectifier and Zener diode(s) with a Podtronic type unit. What year is it? Be aware that pre and post 1971 the wiring diagram and electrics change completely. Pre 1971 the wiring has similarities to the Dominators and is much simpler. Mine is on the cusp of change, it has the old wiring but some later parts, such as the centre stand, so is clearly an interim model, possibly built in 1970 and sold in 1971.

From the documents I have picked up it looks like a mark 2, Registered 1972 but I will need to check everything manually to be sure.
If you don't mind uploading, sending or sharing a link to those photos i would be greatful.

The Haynes manual will allow you to do most things, but I also have the Norton Villiers Commando manual which has detail in it that amplifies information in the Haynes. I use it all the time, mine is very dog-eared. I think you can still get it from Andover Norton.

I'm surprised this book hasn't been recommended, is it not very good?

I think just less well-known among UK riders. I for one have never seen a copy.

Zener?
There is nothing wrong with Zener diodes, they have been going for over 50 yrs. But it would be wise to check the actual voltage of them (I can do this) also the original Lucas plate rectifier some times shows its age with bent fins and corroded terminals, replace with encapsulated square version (I sell). Reg/Rect if all else fails.

Currently I don’t have much of an idea yet what is involved, However I assumed the electrics would be simple given the age, its good to know you can source parts and have information that can help.

electrics
They are simple, especially relative to modern vehicles. However, that all depends on the owner's background and understanding, as is often shown by the questions that come up.....
A lot of problems occur when old (50 plus years!) wiring harnesses are used: corroded connectors, insulation worn through etc etc, particularly the mass of connectors under the middle of the petrol tank , which get even more neglected than the others!
Grant Tiller has done some good wiring diagrams, in colour, which are easier to read. Plenty of reading and digesting info will be worthwhile use of time at this stage, as I have done over 40 years of involvement...!

Invaluable videos from the Club shop
The three featuring the late, great Mick Hemmings are essential, covering, in turn: engine, gearbox, forks and wheels.
It's also worth getting the John Hudson versions, partly because of his years of service to Norton owners, but also because he does cover a few points that Mick does not.

The bike is currently partly dismantled in a garage far from me, so i intend to collect it and set up a local workshop. my father has supplied me with a large bundle of notes, receipts and books of its history.
I intend to separate restoration in to key parts.
Chassis
Wheels and Brakes
Gear Box
Engine
Electronics
Fuel including new carbs & fuel tank (currently original fibreglass).
Please share your thoughts if this is the right way to go.
