Yes, finally, my holidays have started! 3 weeks ahead but well, it looks like summer ended already before it even started; we had some nice days end of june and start of july, but since then… Weather su*ks. Even today, while leaving with grey skies, it started to rain again. So I’ve used my time to look some things over. Since a couple of weeks, the Norton’s taillight doesn’t come on when braking. It works for the rear brake, but not for the front brake. Which is kind of stupid, as I more often use the front brake while just barely, or not even, touching the rear brake.

Following the electrical wires

I’ve followed the wires, from what I can see it is the brown wire, taken together with the red indicator light for the alternator in the headlight shell, followed it under the fueltank but.. Nothing. I didn’t find it (yet). Unless the switch itself on the handlebar is defective, I already changed the switch on the rear brakepedal once, but the front brake is quite well protected. Oh well, I still have 3 weeks left, I’ll find it ūüėČ

While I had the fueltank removed, I did see something else “wrong”, something I already noticed before; when opening the throttle, the left carburator is opened before the right one. This was a perfect ocassion to see it; when opening/closing the throttle, the slack on the cable going to the right carburator was well visible.

Slack in the gas cable for the right amal carburator

The slack, compared to the left, was about 5 mm. By adjusting the cable on the right Amal, both react at the same time. Meanwhile it stopped raining, so I put everything back together again, the fueltank, the buddyseat, the headlight and changed the spark plugs; last time I put in brandnew Champion spark plugs. Maybe co√Įncidence, maybe not, but the Norton was more difficult to start. When I removed them and put back the NGK Iridium sparkplugs that I cleaned, the Norton started on the third kick. The modification by removing the slack on the gas cable could be noticed; when opening the throttle for acceleration, there is no longer the moment of “hesitation” and the Norton runs a bit better too at low engine speeds (2.000 – 2.500 rpm), less “jerky” while riding at a constant speed.

This afternoon I went a bit early to see the Norton. I knew that I still had to look at the right exhaust locking nut. When I removed it, I could see that the sheet copper had done a good job but didn’t resist to the vibrations and force of the Norton after all..

What is left over of the sheet copper

The threads were well in the sheet copper, they even cut through the sheet copper and I had to remove it in fine, thin parts. None the less, it held firm for one year and allowed me to ride the Norton around a bit. I’ve proceeded same way as last time; cut a small strip of copper, put it on the thread, make sure it enters neatly and tightened. We will see how long it will hold again.

To heat the engine up and tighten a last time, I took the Norton for a short ride and when I was in Boulogne on the quai de seine, I saw a biker pushing his bike in the opposite direction. I turned around at the next trafic lights and pulled up behind him. I had my backpack with me with my tools (just in case the Norton would die on me) so perhaps I could help. He explained me that the battery was completely dead as was the battery of his cell phone to warn his friends. I offered him to use my cell phone, but he told me that wasn’t necessary because he was almost there, just left on the next crossing. Hum… Yeah, but “the next left” was in a couple of kilometers.. I don’t know, I could have offered to swap batteries, after all, the Norton can do without, or I could have pushed him, or … But he told me not to worry and he was doing fine.

Strange … I had to push the Norton several times and I can’t realy say that I enjoyed it, so why would someone else push his if it could be avoided? When I came home and told my wife about my afternoon she said “you’ll see, he wanted to push and I’m sure that some 10 minutes later he must have been wondering why he didn’t accept to use your phone”. Oh well, I can only offer help, can’t force someone to accept it if they prefer to continue to push their bike. ūüėČ

This afternoon I wanted to replace the airfilter, but well, I’ll do it next time; I’ve started to open the airfilter box, but then I noticed that the last screw is placed behind the contact, which in turn is fastened too. Even then, looking at the size of the filter Machines & Moteurs sold me, I wonder how it would slide in and out, because the airfilter box opens just behind the Amal carburators, not leaving much room. So I tightened the screws that I already took out and went for a ride.

On my way, I stopped at the flowerstore. The owner stepped outside and we talked a bit about the Norton and Nortons in general before I continued my ride. Then, I noticed a sound I haven’t heared since a while; some hissing and some, be it minor, backfires in the right muffler. Once back home, yep, the exhaust locking nut moved, the one that I had set with the sheet copper. Well, I can’t complain realy, it remained in place for 1 year. So I already know that next time I won’t be able to ride; first I’ll have to set and tighten the exhaust locking nut again.
Vanmiddag had ik het luchtfilter willen vervangen maar dat zal ik de volgende keer wel doen; Ik ben begonnen met het openen van de luchtfilter doos toen ik merkte dat er één schroef achter het contact zit, welke zelf ook weer vaststaat. Dan nog, gegeven de afmetingen van het luchtfilter dat Machines & Moteurs me verkocht heeft, vraag ik mezelf af hoe dat er uit en in kan glijden omdat de luchtfilter net achter de Amal carburateurs opened en er niet veel ruimte is. Dus heb ik de schroeven weer vastgezet en ben met de Norton weg gegaan.

Nadien ben ik even langs de bloemenwinkel gegaan. De eigenaar kwam naar buiten en hebben we een beetje over Nortons en motoren in het algemeen gesproken. Toen ik mijn weg weer vervolgde hoorde ik iets wat ik al sinds een poosje niet meer gehoord had; wat sissing en, ook al bescheiden, wat na verbrandingen in de rechter uitlaat. Terug thuis, ja, de uitlaat schroef was weer verplaatst, welke ik met koper had vastgezet. Goed, ik kan niet klagen, het heeft bijna een jaar gehouden. Dus ik weet nu al dat ik de volgende keer niet met de Norton kan rijden; eerst zal ik de uitlaat schroef weer vast moeten zetten.
Cette apr√®s-midi j’avais l’intention de remplacer le filtre √† air mais bon, je vais le faire la prochaine fois; J’avais d√©j√† commenc√© √† ouvrir la boite du filtre quand je voyais qu’un des √©crous √©tait plac√© derri√®re le contact qui lui-m√™me est fix√© aussi. Mais m√™me, vu la taille du filtre que Machines & Moteurs m’a vendu, je me demande comment c’est sens√© passer parce que la boite s’ouvre tout juste derri√®re les carburateurs Amal et il n’y a pas beaucoup de la place pour manŇďuvrer. Donc j’ai remis les √©crous et je suis parti avec la Norton.

Sur mon chemin je me suis arr√™t√© chez la fleuriste. Le propri√©taire est sorti me voir et nous avons parl√© un peu des Nortons et des motos en g√©n√©ral avant de continuer mon chemin. Ensuite, je constatais quelque chose que je n’avais pas entendu depuis un bon moment; un peu de sissing et, bien que timide, quelques petites explosions dans l’√©chappement droite. Un fois de retour, oui, l’√©crou de l’√©chappement droite avais boug√© lequel j’avais coinc√© avec la cuivre. Bon, je ne peux pas me plaindre, √ßa a tenu presque un an. Donc je sais d√©j√† que la prochaine fois je ne peux pas partir avec la Norton, faut d’abord que j’arrive √† coincer l’√©crou √† nouveau.
