  1. After some work, the lights aren’t coming on

    Electrical Discussion
    I’m very new to vintage Hondas and motorcycles in general, but have done quite a few standard maintenance procedures to my bike since I’ve gotten it. However, after putting my 1972 Honda CL350 back together today after some work, the lights aren’t coming on. I’m not sure where to start since I...
  2. Headlight and rear tail light died out

    Electrical Discussion
    Hi guys, recently purchased a 1979 CM400t. Earlier I was trying to install rear turn signals but when I was fiddling with the wiring, I noticed when I would bump the wires that connect the tail light to the rest of the wiring the tail light would go out. The previous owner wrapped the wires with...

  4. '93 Honda XR250 - Bike dies when I put it in 1st gear

    Other Bikes
    Howdy fellow wrenches (wrenchers? Wrenchees?), I'm having a little issue as I'm putting my '93 XR250 back together. The first mistake I made was not labeling three wires that leave the alternator and go to the regulator. The manual says they should be different colors but for whatever reason, on...

    Hello! Got my new R/R in the mail today, and did a video of me going through the process of replacing the stock one, as well as the battery. Its a bit on the longer side, but I wanted to be thorough and document the small hiccups in the installation I went through. Hopefully at some point or...
  6. Looking For A New Stator! Honda CB Infamy.

    Electrical Discussion
    Hey everyone! I have a Honda CB400A. And lucky for me, my CDI unit went out. As you all know, the CDI units on these bikes are famous for going out. So I’m getting a new one. The only problem is that new CDI’s for this bike are incredibly hard to find. And IF you happen to stumble across one...
  7. CB360(ish) No turn signals or horn

    Electrical Discussion
    Hey there, new to bikes and forums in general. Recently got my first bike which is a '74 CB360T, I believe, that had an engine swap with the one from the '76 CL360 - the scrambler. I figured it was worth making a new post since there's a couple variables there. Right now when I turn the bike...

  11. Anyone use smaller SLA batteries with "T2" terminals?

    Electrical Discussion
    I'm working on a cafe/tracker cb450 build and am in the process of finding a small battery. On the common motor collective website FAQ they mention you can use small SLA batteries meant for in home security type systems. But all I could find were batteries with these T2 terminals. I ended up...

    Well, title tells it. Previous owner allowed the battery to completely die, kick started it and rode it that way for an unknown length of time. Result, every light in the house is burned out, horn no longer working and there is a serious misfire under load (when riding) with a new AGM battery...
  15. Aftermarket Tail Light Wiring

    Electrical Discussion
    Hey guys I need your help. I decided to shrink the tail light on my CB400t II using an EMGO model I'd seen somewhere on here. The problem is that the stock light has 3 wires and the new one only has 2. So I've got it wired up to flash bright for braking but I cant get the low light setting to...

    Electrical Discussion
    Hello everybody! I've been doing a load of research on my problem but haven't been able to figure it out, so I made an account to ask for help! A little backstory - I bought this bike nearly 2 years ago and it ran (rough but still ran). I didn't even ride it before I started tearing it apart...
