  1. 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...
  2. '71 CL350 Bogging after Hard Ride

    Engine Discussion
    Hi all, I haven't been posting as much since my bike had been running well for almost a year now (no news is good news?). In February, I took it down to the desert in southern Utah, and a friend who rides MX treated it.. like it wasn't an antique. It bogged under acceleration and I chalked it...

    Electrical Discussion
    Good evening! I am the owner of a 1974 CB200 with just under 1k miles on the odo. The bike runs and rides great after an extensive carburetor overhaul, however it seems something in the charging system is amiss, as it isn't keeping the battery up. Let's go down a list of everything I've done...

    Electrical Discussion
    Ok so lead acid batteries, great, heavy, don't hold a charge for that long, expensive-ish to replace..... Ballistic lithium ion batteries, holds a charge, runs at a little higher voltage.. more or a pain due to balancing the cells.... SO, i've already run through an expensive ballistic lithium...

  15. 1980 CM400T Battery upgrade; Mosfet vs Rick's R/R

    Electrical Discussion
    I'm building a cafe racer and need a smaller battery that I can mount anywhere. The bike is only electric start so I don't know how big of a battery I'll need either. Not sure whether to get Li-ion or AGM. Also, I'm assuming I'll need a new R/R to go with it. I've seen good things about Mosfet...
