    I'm also contemplating on putting a hugger/rear fender on the swingarm, to keep mud and dirt from spraying all over. Did this on my old Kawasaki Ninja, and it makes a big difference. As it hugges the rear tyre pretty tight it doesn't take away too much from the design either. Does anyone now of...

    Today I mounted a new OEM clutch cable. The old one was so worn, that I almost had to use two hands to clamp down the lever.. The new cable was about 10cm shorter than the old one, so maybe one of them wasn't exactly the right cable. I needed a shorter one, so that suited me well anyway. I...

    I might have measured wrong, somehow. I agree with you that there's no reason for copper wire to have som much resistance. Either way, I'm leaving this for the time being. There's som many other things to do ;)

    The wires have a stranded copper core, and measure the same resistance with or without the Dynatek cap. From what I can see on the internet, 1Kohm pr foot is not uncommon for copper-core wires.

    These are the rearsets I made a few years back, and I'm looking forward to finally try them out: I'll use the old gear lever at the front, and connect the linkage on the inside. At the back, I'll connect at the outside of the lever:

    Checked the old caps, and they are 5Kohm NGKs. Descided to measure them, and this is the result: 35Kohm seems like the logical explanaition for the hot coil. The numbering is not cylinder-number, so both 8 and 35 could be on the same coil. Measured the new wires, and they are about 1Kohm...

    Does that apply to the gs750 E (16 valve) or GSX 750, as it's called in Europe? I couldn't find out if it did, as the gs750 (8 valve) originally came with R plug, and the gsx750 came with no risistance plugs. The service manual for my bike, lists D8EA as the right plug.

    Btw, the reason that the bike didn't start yesterday was probably a bad connection from the egnition, leading to the coil not discharging. Probably got damaged while the bikes was in storage. Runs well now :)

    Wired up the coils and shortened the spark wires :) Also bought new spark plugs: The old ones where the plugs that are intednded for the 8valve engine. The main difference I could spot is that they have extra internal resistance for noise suppression. Does it matter which one I use?

    Wired up the ignition to test if the engine would start. It didn't, and the left coil got extremely hot. I won't bother with any troubleshooting, as I've already bought a set of Dyna coils because of the worn out plug wires and bad looking OEM coils: Does anyone have any experience with Dyna...

    I know.. It breaks my heart :( Luckily, I took off some of the parts before I put the bike away. The old shed where I kept the bike was more damp than I knew. I cleaned and refurbished the carbs and painted the engine the year before, and now it looks like crap. The aluminum surface of the...

    Fitted the throttle today, and the wire is extremely smooth. The kit came with three different cams; green, white and red. The red cam gives fast resonse from the start, then tapers off. The white has a greater circumference all the way around, and requires less twist to full throttle. The green...

    The finish is great: It seems like the barrel clamps down really well. When all is good, I'll fix it with locktite and keep a spare with me. I had to cut a couple of strands from the old cable, as the Domino cable is thinner. Here's a test with some old gsx750 carbs: The original cable...

    I want the bike to be easy to move around, so I'll start with throttle, clutch and brakes. I've ordered Domino XM2 Throttle with universal cable kit. It's a push/pull setup, but I will only be using one cable and block the other holde. Then I have on in reserve. The sleeves are teflon-lined for...

    Haven't ordered anything for the bike in a couple of years, so I decided to fix a problem I've postponed for a while. I've bought some really cheap turn signals from ebay earlier, and they've all turned out to be crap. In sunlight it's almost impossible to notice when they're blinking. Two of...

    Will definitely test that out. I remember NURBS becoming a thing, but Youtube wasn't a thing when I dabbled in 3D modelling, so the learning curve was too steep. I've looked for a way to model more organic shapes, so Rhino looks interesting. One thing i did try, was "generative design". For...

    Thanks! :) I don't have anyone to compare myself to, as the guy who owns the CNC only uses it for wooden cabin signs ;) I use Fusion360 (non commercial license) for modelling 3D printed parts. They arre printed via Ultimaker Cura. For CNC, I used the software my friend already had, Vectric...

    One final point for today: I read through my discussions with posplayr about correctly grounding the R/R etc (https://www.thegsresources.com/_forum/forum/technical-forums/electrical-ignition/86540-m-unit-blue-on-the-1982-gs750). I learned a lot from it, and I think he and I were essentially...

    When researching how to route the wires, I also came upon a diagram showing how to route the cables: Wire routing_3 by Lars Krogh-Stea, on Flickr The same problem arises here, as the handles are so low, that the cables must be routet differently. I will have to do some googling to se how...
