Has anyone fitted aftermarket gauges to a Commando? I remember Dreer using Autometer gauges on his previous bikes. It'd be nice to have a tripmeter, but I'd like to retain the original mounting cups. The Hemmings tach isn't bad, but I haven't seen a speedo to match. I once saw a Smith's speedo on EBay with tripmeter and the NOrvil logo on the face but didn't have spare cash at the time.....
Thoughts?

| I just scored an Autometer bike speedometer on E-bay (sweet!) and I'm on the lookout for matching tach. I will let you know when it gets here if it can be fit into the standard instrument cup. I'll have to fab up a speed sensor for it. Any input from somebody who has already done this will be appreciated. |

the chopper that I just finneshed up has the autometer pro cycle tach and speedo. I had to fab up a speed sensor mount and it does work after severel speed sensor's burnt up. I have to call autometer tech tomorrow with a few more questions but all in all it can be done but I also changed to neg. ground to make it simpler to get electronic stuff. the bike can be seen at the site below.

| So, can you post a close-up of the sensor installation and write a short post to let use know where to find the sensor and what the issues are (how did the sensors get burned up?) and also, does the instrument ground to the case, or can you just wire it up "backwards"? Thanks. |

I have to call autometer tomorow and after that I will have more answers for you. if you send me an email @ windyae@earthlink.net I will find a picture for you and will tell you more on the speed sensor.

ok. i talked to autometer yesterday and they confirmed that you MUST HAVE NEG. GROUND but i changed the chopper over allready. the speed sensor that i used is a HD part #74420-94C the trouble i had was EVERYBODY said it was 12 volt and after the third one and a second call to autometer i was told to use a 65 ohm 1/2 watt resestor. well i wound up with a 1K ohm 1/2 watt to drop the voltage AT the sensor to 5 volt. apparntly nobody knows how harley has theirs wired. i am thinking that HD has a droping resestor in the speedo head. as for a mount for the sonsor i made a piece that centers off the rear axel and go's to the front of the sprocket, the sensor faces the sprocket from the front of the bike and the peak of the sprocket teeth. i still have a small bug to work out as he told me that it does not want to read under 20mph it might be to large an air gap or i might have to move the sensor to the side of the teeth. i will know more next week on that problem.
the tach is nice except that it bounces very badly at idle and autometer told me that is the price you pay for a very responsive tach. looks like it could use some kind of dampnin to stop that but it is quick to move.
if anydody wants to talk email me and i will give you a # to call.

| Hey, Chris. My e-bay speedometer came and it definitely won't fit in the original cup. I'll have to come up with some type of bracket for it, but I'm fishing for a matching tach at the moment. |

| The speedo comes in its own nice chrome pod, so it is meant to be mounted in some kind of ring, I guess. The body is 3 7/16, which according to my quick measurement of the clocks on my bike (I can't find the cups I have laying around) is too big. There is a step in the body so that the speedo face is even larger, I think 3 3/4. I think they used to make a smaller series that probably would fit into the cup but I don't know if they still do. IMO, the stock speedo is way better looking and not as clumsy. But, if I can pull this off, the advantages of being able to program it for any tire size, accuracy, no cable, no fragile Smiths drive, and (I presume) good internal lighting make it an easy choice. |

The Unapproachable Norton Commando
At the end of 1967 the Norton Commando was announced.
The Norton Commando was greeted with a certain amount of scepticism because on first sight the commando appeared to comprise of the old Norton Dominator twin cylinder engine mounted at an inclined angle in a set of new cylinder parts.
It was not realized that the new Norton Commando Isolastic method of engine suspension damped out all engine vibration and produced a machine which had uncanny smoothness for a vertical twin. In due course the critics were silenced and the Norton Commando had the distinction of being regarded as the first of todays so called superbikes. There can be little doubt that the original design concept of the Norton Commando has proved correct, since comparatively few modifications of any real consequence have been made since production commenced during 1968.
Now nearly 40 years later Norton Commando riders like us are a breed of our own, and as far as we are concerned its still more fun to go for a blat on the old Norton Commando, and fast. As a Norton Commando owner and enthusiast, my goal here is to promote and give credit to those who keep the Norton name going.
It is more deserving to give credit to the Commando itself, for after all these years it continues to be respected. The original Commando designers like John Favill are those who deserve the credit for developing this incredible motorcycle.
The Norton Commando Roadster and Interstate of the late seventies, never died. Although the Norton Villiers factory dispersed the tradition lived on. Today Kenny Dreer in the USA is developing the new 952 CC Norton. What a great looking bike this is, and its engineering is still based on the original layout. It will be interesting to see how the new 952CC Norton does in todays tough motorcycle market. One thing is for sure, I would own one if I could afford it.
