Wow!

This is an abnormal wear!
Most likely due to insufficient lubrication;

It must be taken into account that it could also be a material defect (incorrect hardness or wrong surface treatment) has already occurred in the past, and some cases are known

Yes, agreed: mine had very worn guides after only 25,000 km, and no smoke, but then I had this, demonstrating there was no oil reaching the inlet rocker.

You can't really see the wear in this photo, but the guide was oval, and there was a lot of rocking between the stem and the guide.

That's correct Banquo;

I just note that on my NF Carabinieri, with motor in perfect conditions and additional oil line fitted , he does not smoke,

meanwhile on my NF Civile ,with tired motor , and additional oil line, he does smoke a lot

I think you're right Randall, but as it only occurred after fitting the oil feed, it does suggest there wasn't any oil reaching the valve gear with the stock lubrication system

with all due respect for the considerations made,
according to my personal opinion, the smoke is due to the wear of the valve guides

I wouldn't run the idle really low as as far as I can make out no oil goes to the cambox until the idle is up in the range of a normal brit single. The bypass valve doesn't come into play until the pressure comes up with a few more revs. Leastways my single  smoked copiously at very low revs after I fitted the additional  oil feed. Once I raised the revs slightly to the same as my sidevalve singles it stopped smoking. At what revs  the bypass comes into play would entirely depend on the efficacy of one's oil pump. Of course if one's pump was poor in the first place then it might never smoke at all. Just a thought....

Electrics / Re: Single wire alternator conversion?

In reply to Patentgeek’s post about single wire alternators, here are details of something similar that I have fitted to my NF custom build.
Having said that, I do not encourage non original modifications to machines which are otherwise standard and perfectly capable of working efficiently with the standard equipment.
However my requirement was to replace my ‘dead loss’ battery system with something small and neat which would allow me to use my headlamp during both daytime and night time riding.
I came across (or should I say Banquo came across) a Kubota 12 amp permanent magnet alternator, as fitted to lawn tractors, etc.
It is very small and neat and driven via a standard Z 21.5” vee belt.

As can be seen in the photograph it mounts on the standard dynamo mounting lug and just needs the addition of a small tensioning bracket at the front.
However it is not a single wire system. In fact it is a six wire system but it is all very simple to wire in place.
Because it is a permanent magnet device there is no control of output and so the spare energy has to be dumped through the separate voltage regulator, though heat loss.

IMG_4239 by bancquo

My voltage regulator is mounted under the saddle, on a heat sink (bit of sheet steel) in an area where there is some air movement.
Due to the small size of the alternator pulley the rotational speed is about 2 x engine speed. However on my bike, which is fitted with a smaller than standard rear sprocket 50 mph is equivalent to 2500 rpm. This means that the alternator will be doing 5000 rpm at normal cruising speed.
It remains to be seen if that will be too fast both in terms of bearing wear and heat dissipation through the regulator.
Time will tell !
Something that was really strange was that the purchase price from an Australian supplier was nearly £100 less than a UK supplier. But then I had to pay custom charges which did reduce the saving a bit.
Weird though !!!

So, to summarise, it fits very easily on the original dynamo mounting lug, and maintains the minimal look of the bike.

It's not road tested yet but everything is looking good at the moment.
