Hey everyone. I have a bad spark unit. There are some OEM ones online but I sort of hate to replace an old part with an old part from someone I don’t know. Are there any good aftermarket spark unit replacements? Anything with a heat sink? Thanks for your ideas!

Do you know what the spark units actually do? Are they kind of like a relay? I haven’t been able to figure it out.

Bob can you pull off the left side cover and see if you just have two black boxes (CDI) or a set of points spinning around? I thought the CDI was the physical unit that's housed under the left side cover. I know you know more about this stuff than I do so sorry if it's not helpful.

Bob, that's really helpful, thank you. I'll look into that! Would be a nice explanation for why 2 and 3 are gone together. I'm reading my Clymer manual right now. You came here for help but instead you're just educating me! Thanks for the help.

Hey thanks Bob, those are good ideas. I have a 4 carb setup on mine. Plus 1 and 4 are coming out alright, 2 and 3 are coming out dark and wet. When you say swapping the spark units do you mean the coils? I'm not sure if that's different name for the same thing, but yeah, I tried swapping the coils.

Bob I'll be curious to hear what you find out. I'm having a similar issue and have gone through a similar work-up, although my bike was running well prior to this happening. I was unaware of the pulse generator possibility, I'll have to look into that more. I also have an 81 CB750C. sync'd...

AMC, that makes really good sense. Thanks for the information. There's a motorcycle scrap yard near me that I'm going to go look through, otherwise I'll go for eBay. I think I'll take your advice and pull out the cable to get a look at how it works and how it broke.

Cool, thanks AMC.

Cool, thanks AMC. What do I need to know to get the right cable? Do they come in standard lengths? And if you do feel like bothering, I would like to know why it does that when it's broken.

Ha. Thanks AMC. I know you give good advice so I'm not too worried.

Hey team, My speedometer isn't working. I have an '81 Honda CB750. I looked at the drive gear and it spins freely and the teeth are good. I think it's an issue with the cable. Here's what I've noticed. If you stick a flathead into the wheel end of the cable and twist it, the square peg on...

I'm thinking that I'd like to have a good way of labeling wires where they're joined into connectors. My bike has a lot of non-factory wiring, so a lot of the documentation is irrelevant. I keep my own records but it would be nice to have labels right there on the bike. I've seen people use...

Hey team, Has anyone found any really good way to label wires? Anything way better than some masking tape + permanent marker? That's all I've tried so far. I'd like some new ideas. Kevin

Figured it out! I wired them into the running light wires. Classic.

Hey everyone, This forum is a great resource. I've learned a lot without even having to post. But I haven't been able to solve this problem and I'm hoping you guys can help out. I went through the process of installing an LED rear taillight and installed and LED flasher so that it works...
