The Norton finally has a name! Or well, my wife gave the Norton a name, I’m not quite sure what to think about it. First she called the Norton my Mistress and that she could smell my mistress (warm oil) when I came home. Would indeed be difficult to hide it from her when I took the Norton out for a ride. As I still have some problems with the right exhaust locking nut, though I managed again to tighten it again somewhat, the jointure isn’t quite airtight, she’s blowing a bit of exhaustgas through the jointure. Not much, but enough to “hisss” again a bit and hence why my wife calls the Norton now “Daffy” (from Daffy the Duck); “Sssszzuper, a Norton” 🙂

Meanwhile I also looked, again, at why the brakelight doesn’t come on when using the front brake. I thought to be smart and check first if the switch itself is perhaps defective.

Frontbrake light switch

I had to loosen and turn the master cilinder a bit just to be able to lower the protective casing a bit. First I measured the negative power, OK. Then I had a brilliant idea, put a screwdriver between the two contacts and … Nothing. The brakelight still didn’t come on. That means that the problem isn’t the switch, but somewhere else in the wiring. So next time I’ll have to remove again the fueltank and check again the nice tie of wires there.

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 😉

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 coïncidence, 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. 😉
