    If you fit electronic gauges to a Commando, what you really need is a modern bike. It is very rare these days to see a classic bike which is correct in every detail. A few years ago, I saw a Thruxton Velocette at Phillip Island which was nut and bolt perfect. It made me feel good to see it in that condition and I don't even like Velocettes. The beauty of a perfect classic bike, is that young people can see what they actually were when they were new. Would you paint a moustache on the Mona Lisa ?

    In Australia, we have several bikes in historic racing which have Scitsu tachometers fitted to them. It solves a problem, but would you do that to a close to original Manx ? There is even one two-stroke which has a full go-kart engine management system fitted to it, with the gauges on the top yoke. To anyone who knows what they are looking at, it is a piece of shit. Yet the game is supposed to be HISTORIC racing. I had to laugh - a few years ago I came across four old guys at Winton who had perfectly restored road bikes. One of them told me they'd had a look at the 'historic racers' and were simply horrified. It is just a bloody joke - there is no attempt at achieving authenticity.
    I am not a purist, but at least I try to make my bike look like something which actually existed back in the era.

    If that mustache actually improved Mona - then I'd say go for it.
    My motorcycles/sportscars get configured to please me - go ahead and do whatever pleases you.

    I suppose replica Seeley frames, modern fuels, paints, oils, ignitions, chains, non original engine and transmission internals, tyres and tubes etc are perfectly OK in vintage racing...
    I,m with Dutch, and do as I choose to get my vehicles how I want them.

    "Tom Kullen does a neat kit using old speedo drive housing with guts removed and magnetic internals fitted."

    +1 on Tom's kit, have had one on my ES2 for a year or few. V Nice. And even i could do the conversion.

    I had the speedometer cable pull out of the rear wheel drive and my rear tire rolled over it, damn near pulled the bars out of my hands. Got a new one and it did the same thing!
    Did some checking and they were supplied by Barnetts, went back to the shop that I got it from and showed them that they had a problem by pulling the end off at the counter with little difficulty. Went back to cables from AN, never had a problem since.

    Eddie/Tom - thanks, I contacted Tom through the website and will be purchasing the kit that removes the guts of the speedo/installs the sensor inside.

    OOPS... Sadly, Tom is out of stock on the speedo gear kit. :( He's working on getting more made up but he said it would be at least a month 'till any are ready. We'll be driving to Mexico the first week of Dec - before they will be ready so when I get down there I'll install the sensor that came with the speedo/plugs into the speedo gear.

    Even though the speedo gear is working fine, I guess I'll remove/clean/reassemble/re-lube it to ensure no problems. I plan to order the speedo drive kit when we are back in the US in March...though I won't be back to the Norton (Mexico) again until next December.

    Hello,

    I also want to get rid of my speedo gearbox at the rear wheel and put a electronic smiths speedo on my Commando.

    so my question: when i take the speedo gearbox off do i have to keep the spacer [NM13270]?

    How did you do it?
    or have you put a solid spacer in with the same depth/length [hope you get me with my autrian english :)] as NM13270?

    Do you guys have some pix from the reed sensor and magnet assembly?

    have a nice day, chris

    Chris, I can't help with your specific questions, not having installed anything yet but, FWIW, I decided NOT to go with the reed sensor/magnet assembly. The reason for my decision was based on the website's info which stated that the reed sensor/magnet was not accurate at low speeds on a 19" wheel because of the length of time it takes the wheel to rotate around and the magnet to again pass the sensor. Admittedly, that inaccuracy allegedly occurs at speeds below 15-20 mph which probably doesn't matter at all in the real world. I just don't like the concept of buying something that doesn't really work like it is supposed to work. To be fair, the site says you can buy an additional kit - or maybe it's just an additional magnet, I can't recall - and that will resolve the issue.

    In any case I decided on the speedo gear kit which retains the housing but removes the gears from it. That keeps the stock appearance - if that's important. It also means I don't have to come up with spacers to replace the Speedo gear. Not that that's a big deal - some washers will do that! :)

    Not true and not sure why that is posted on the site. I have a single magnet on the hub (18" wheel) and accuracy at low speed is fine.
    You also have the option to put on multiple magnets for improved accuracy (19" wheel?) and just adjust the setup of the speedo to compensate for multiple pulses per revolution.

    That was indeed interesting, Thanks.
    Did you generate a drawing of the custom-machined part?

    I will send the drawing to you via PM.
    Note: it is only about 200 km on my bike. More testing next year. So use at your own risk.
