I believe that Mark Bridger of this parish has repaired one, but concluded that it isn't commercially viable to do so (?).
Only other help may be to look up 'Ferrari Dino' rev counter repair as they are very similar inside.

Yes. Original neoprene bit had a conical face towards the cover, more recent ones are straight. Conical needed around 1mm 'compression', newer type nearer 2mm.

The originals on my 1978 were clear/opaque plastic, approx 5mm bore. In its time, mine has had fish tank air hose, black rubber pipe and currently has PTFE hose with rubber 90° elbows on it. As long as it flows some air and any emulsified oil can escape it will be ok.

Hi, Whilst no one has replied, I know that some people with way more knowledge than me have done a repair/rebuild of these, but it isn't an easy job. The most recent posting on this subject was that somebody replaced the 'guts' inside with those from a cheap Chinese generic rev counter for very litt...

If they were mine, I say it depends on how and where they have been stored. Sealed away from light and excessive temperatures they should be ok. Hanging on a nail on the shed wall and it's a no-no. I fitted a 4 year old belt last year, to my Sport but it had ben kept in the sealed poly bag it came i...

Most important - make sure that the key isn't too tall when installed! The key should 'stick out' of its slot on the crank much less than the depth of the slot on the flywheel. It's ONLY job is to locate the flywheel in the correct position (so tdc and strobe marks are correct) and that is all. The ...

Hi, I have no experience of Motobatt, but the original size battery was a 12N9-4B, ie 12v 9Ah. This suggests that the MB9U as Jen suggests would be correct size. That said, how long does everything last? An AGM battery of the same size is 1/3 the cost of a Motobatt, and the ones I have experience of...

Oh no!
Collarbones are painful in my experience! Hope that you mend well and soon!
Sounds like bike hasn't got any difficult to get bits broken which is always good news.
Get well soon,

Well Founders Day was a great event despite the weather doing its best to disrupt things. More than 30 Morinis on the stand, with bikes covering 1948 to 2024!
A very good image builder for the club.
Well done to all who helped out over the weekend.

As you were tinkering at the back, is it the bush that goes over the indicator stem to stop the rubber mount crushing? From memory, they are around 8mm ID, 10mm OD and around 12mm long.

OK, so for the idle to be too fast, something isn't right. There is too much air going in from somewhere. Have a look at the following for some more ideas. I will assume that the throttle stop screws are wound out to have no effect on the slides and the slides fully close in the bodies and that ther...

Timing: Yes, same as standard.
You are lucky enough to have the original pick up as the NLM one can be a difficult thing to set up.

As has been said quite often, are the slides in the right way round? (Cutaway towards air cleaner)
Easy mistake to make.

You have got the NLM ignition system on your bike. Well, at least part of it.
The bits in your picture are usually ok, it's the trigger part on the camshaft that can be awkward to set if you have that part as well.

Hi,
Regarding the red light, if you have an earlier bike, the most useful thing to do is to convert it to an indicator repeater light instead.
