Recommissioning a Dommi 88

Posted by graham_parker at October 23. 2017

Hi all

I'm completely new to Nortons, but have taken ownership of a 62 Dommi 88 SS.   It is in excellent condition, but has been stored and not run since 1998.

I have (or am) cleaning the fuel tank / carbs etc and am obviously changing the oil / draining the crankcase / flushing the oil tank, etc.

I've sprayed some WD40 into the bores and kicked it over many times with plugs removed and can see that oil is being drawn from, and returned to, the tank by the pump.

I have a great spark at both plugs from the Mag (it has been converted from dizzy at some time).

I would be really grateful if people could suggest anything else that I should do before firing it up or anything else I should look out for during its early running.

Thanks in advance and apologies if I'm repeating previous posts (I did a search for recommissioning but didn't get much back).

Cheers

Graham

 

Thanks in advance and

As soon as started block the return with a long finger and flush the head oilways for 10 secs ,you will probably see some smoke and be prepared to have to change the plugs as they may soot up, get the choke off as fast as possible to avoid this.

It sounds like you have done all the right things - basically a full service. Robert's suggestion is a good one. Don't be too surprised if you get petrol leaks. Just watch carefully as you fill the tank and turn the petrol tap on. If it's reluctant to start, you may have to strip and clean the carb.

Earlier this year I recommissioned 2 bikes that had been lying since 2000. The BSA was completely trouble free. The Enfield had a gunged up carb. Both are running well.

Thanks

I might "syringe" some oil though there directly whilst kicking it over with plugs out.

Cheers

It might be worth giving the carb a real good clean out to get rid of any varnishing or any other gunge. You can get a full service kit from Amal. I have a 1960 99 (62 reg) 12 months ago that hadn't run since 1999/2000.

I did just about everything you have done plus a clutch rebuild, new oil lines, carb service/rebuild and installed a Thorspark electronic ignition in the mag, (never looked back with that). Just new tires and chain required and then it's back on the road (well after May 2018 so I won't need a dreaded MOT).

Best of luck with the project

John

Just a quick note to say thanks to people above for advice.  Cleaned tank & serviced carbs, new plugs, loads of WD40 down the barrels and kicking over with plugs out, new plugs, new oil and rockers primed, new fuel lines and fuel, no leaks and started first kick - i'd upload the video but its a bit bigger than the attachment limit!!!!!

Absolutely lovely Graham,  I especialy like the line of the small bore exhausts ,no horrible corner bends.  Did they fit the DD head to the 2 tone 88SS?, Perhaps not?, but who cares. I would have preferred the 2 tone seat, cheroot silencers and mono's but the Concentrics are practical.  Love it.

Delightful! Good to see someone has done the go-faster upgrades - downdraught head, alloy rims - without feeling obliged to go the full cafe racer look. Impeccable good taste.

It's actually not a good idea putting WD40 down the bores, or mixing it with any lubricant.  WD40 has lots of detergent in it, and it destroys lubricants.  It's far better to put a very light oil down the bores instead. Also, never use it on control cables, for example.  If you are worried that the rings have stuck, try TF2 or GT85, they are a very light oil with teflon

I would also advise ethanol proofing your fuel system - replace petrol pipe, the fuel filter in the carburettor banjo, and the float needle.  The tank tap may need attention as well

Your tyres are probably time expired.  There may be other rubber components needing

replacement.

You have a nice bike

Paul

So I used the term "WD40" loosely - I actually mix my own - paragon and engine oil - and I changed the oil a couple of days later.

 

Tyres are in the garage waiting for me to fit them.

 

The rest - wellI I guess I'll find out 😁

Hello Graham well it looks a sporty prospect and in the right colours too but the carburettor are for a much later model you should have fitted, mono bloc  376/288 and 376/289  which are the correct ones for this model  now you can buy New ones at £157 each  and you should have inlet sleeves fitted as standard, yours  anna j

The paint is lovely!  Whoever stored it in 1988 did a great job.

Hi,

A beautiful example, hope it works out okay for you and the steep learning curve isn't too painful and costly.

Anna, usually get things right, but seems to be in danger of becoming a "Rivet" counter!

This is no personal criticism of you Graham, but, years ago it was a restoration job and "putting the machine, back on the road"!

Recommissioning? Sounds like Bonham's speech! Strange how as, Auctioneers, Investors and Speculators have got involved, the terms of reference have got more "flowery".

I have read some of the Auctioneers blurb in the past, usually based on a lot of plagiarised quotes, hearsay, supposition, and inflated claims, but the best thing is it gets repeated on Ebay with regards to mass produced "common or garden" stuff!

Rare... C15 Star....this model was...Isle of Man TT....and is... a gem of engineering .....yours  for the bargain price of... £4,700, bargain, a truly solid piece of motorcycle history, successful @ scrambling and as a 1/4 litre racing mount, and as good as it gets a solid Gold standard,  future Investment....!

Sad to see and increasingly inflating the cost of partaking in our beloved "Hobby" of motorcycling!

Cheers

Well if you do not count your rivets you end up with a sinking ship  that's what happened to the British motorcycle industry  its some 50 years trying to claw its way back into the motorcycle industry   triumph/Royal Enfield  has made it back but the rest have yet to follow  Norton for me as lost it way,  and only god know were it's going !! only time will tell ,     yours   anna j

They should have welded the plates together, rather than rivet them, my friend!
