  1. Electrical Issues
    Hey all new to the forum but glad to be here, I got a 78 Cb400T hawk the other day in great condition, everything was working fine. Two weeks later my battery dies, the thing doesn’t run at all and I replace it ( I’m using lithium ion because the person I got it from stripped everything and...

    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...

    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...

    I have been repairing my wiring harness 1971 sL 175 for three days now. Upon studying the diagram I can see all the symbols for ground, but I’m not sure how many ground cables to frame I need besides the battery to top right motor mount grounding cable. There’s also a ground in the headlight...

    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...

    I have this extra wire coming out of the wiring harness that is continuous with the green wire in the regulator/rectifier plug. Where is it supposed to be connected? I can't find any mention of it online.

    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...
  10. Project Logs
    I've recently acquired a 1974 honda cb450 with 11k original miles. I don't know how long it has been sitting, but I am wanting to get it to run again. I figured I should make a thread in project logs since I'm going to be asking so many questions, and I'd rather not have to post tons of new...

    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...

    Hey guys - My battery needs replacing and I'm having a hard time getting the seat latch to open. Last time I opened it, a couple years back, it was in working order but now the sucker just will not release. The lever has some play but still won't release the latch. I've tried pushing down on on...

    Hi y'all, I am working on a new to me 1980 400t I got from a friend for the best possible price (free). The stock airbox is long gone and the bike came with some cheap pods. Per the thread in the fuel section I have made some ~3" velocity stacks out of schedule 10 pvc to get the cheap pods the...

    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...

    Hey Guys, I've got a 71 CB 350 that im in the process of a resto/Cafe project. Im a bit confused on what is needed as far as minimum specifications for a battery to run the bike. I have removed the starter and all similar parts so its strictly kick start only bike. Because of this I do not...

    I'm building a cafe/brat out of a 1980 CM400T. Looking for a low profile battery that will work with the factory electricals and able to mount sideways. Also, any tips for new battery leads? I plan on mounting the battery under the seat. I'm dropping the signals and only running a brake light...
