    So, this is the wiring diagram for the bike: Noisemaker_koblingsskjema by Lars Krogh-Stea, on Flickr First time I wired it up, I made several mistakes: I used a lot of "velour tape" (looks like old electrical tape), because i thought it looked cool. Ended up with very a very stiff and...

    Well.. I'm almost embarrassed to revive this old thread:hopelessness: Started in 2015, and still the bike is not roadworthy (even though it was for a couple of weeks, before I started the fork swap). It got put in the back of the garage in '21 as my work in hospital leadership became too time...

    Wired the bike up enough to start it today, but the throttle is stuck. It's not the wire, it's the shaft for the butterfly valves. I'll pull the carbs when I have time and clean and oil the shaft and linkage. Annoying as...!

    The cables come as two wires with coil connectors in both ends. You cut them to length and crimp the plug connectors yourself.

    Hope you got it sorted quickly :) Here's the description from the ebay ad: 2021-06-20_03-17-10 by Lars Krogh-Stea, on Flickr Keep in mind that I haven't mounted or tested it yet, but it should be the correct parts :)

    Well.. Today I'm both happy and annoyed with my self. Last summer I spent hour after hour trying to get the petcock to flow enough gas to make the bike pull at higher RPMs. I overhauled the carbs, changed fuel-filter and more. I was convinced that the only thing I had changed from when the bike...

    Awesome, keep me updated! Would be great to exchange ideas and info about making motorcycle parts :)

    Hi! Yes it's the MPCNC (Mostly Printed CNC) from v1 Engineering. It's the new model and they have redesigned most of the parts for greater stability and accuracy. I haven't had time to assemble it yet, and probably won't before fall. When I do get it up and going, I'll post some videos from the...

    This is the mess I stitched together last summer to get the bike rideable.. Hurts my eyes to look at it :o This is the new electronics box with the M-unit Blue and ignition module. I also integrated a copper ground terminal. I'l draw some sketches to see how to best route the rest of...

    And for those of you that thinks this has become a 3D-printing thread, I'll soon be doing the linkage for the gearshifter and the front brakes. In that regard, I have a question about steel reinforced braided hoses. The set I ordered earlier are for the original fork. Those are too long for...

    As I'm redoing parts of the electrical system, I will also replace this: with this: It takes 15 hours to print, so I hope the measurements are right ;)

    Another 3D-printed part finished. This one is a bracket for making the rear light level when mounted on a surface that sits at a 45 degree angle:

    And I made one for the gear-indicator: I think that's the last part I need to print for a while. There's some wiring left and connecting the front brakes, and then the front conversion is done. Then the bike will be rideable again :) Still need to make a proper mount for the registration...

    I made a housing for the Motogadget Mini. I'll glue this into the triple so I won't have to glue the Mini directly. 3D printing doesn't give a perfect surface. When the CNC-router is finished, I'll probably go back and recreate these parts in aluminum. Meanwhile it's a cheap and easy way to...

    The front is slowly coming together again. I'm not using Weather Pack connectors here as it's much easier to put the clip-ons together if the connectors fit through the clamps and the connectors will be located up under the tank so waterproofing isn't as important. I think the result looks...

    The last couple of days I've been testing a few designs for the control-housings. I pretty confident they are in their final iteration now. Today I designed and printed the headlight brackets. They're attached to the fork-legs by stainless exhaustclamps.

    Started to do the wiring for the controls. I'm drilling a hole in the clip-on tubes for the wires (from inside the controls) and I'm running the wires inside nylon sleeves for protection and looks. I wont bother with Weather Pack connections as the connections will be inside the headlight. I've...
