Clutch was slipping yadda yadda, i bought new plates all 14(?) of them, excluding the double plate for my '78. While i'm inspecting the old friction plates i notice that the material is nearly gone on some of the friction plates. I had also noticed the oil light coming on while the motor is...

Alright, I bought this bike last year, it's a '78 cb750k. The previous owner was planning on having it be a cafe racer style bike. He was almost done, but encountered an "electrical problem" he told me. It did not run when I bought it. I spent that summer and winter tinkering, fixing, cleaning...

obligatory 1978 cb750k I got this bike about a year ago and finally got it up and running this spring. I’ve been riding it around town and to work and such, no apparent problems with the brakes. About a week ago I found out the brakes weren’t in tip top shape when I needed to stop very...

Hey all, at this point I'm a regular on this site and am learning as I go. Right now, I'm experiencing an issue with my 78 model that so many have had and will have. A rough idle. Only difference is mine doesn't die on me! She sounds more like a harley than any of these bikes should while...

I understand that these bikes are pushing 50 years these days but surely there’s still a way to get new clutches (plates and springs) for them right? I’ve done some digging online and found only one place that seems to sell it as a kit. After a little more digging on some more common sites...

This post is really asking two questions. Is there a way/What’s the best way to tune the carbs without those pressure gauge setups that I see on youtube? Also, my bike used to run fine-ish, but lately it had been choking itself out. It would run fine for a spell, then stop revving past 3/4k and...

To start, I'll say I don't have the "proper tools" the manual wants you to have to test the alternator, the best I've got is a multi-meter that reads AC, DC, and resistance. I've gone through and checked what I can on the alternator itself: the resistance. the field coil reads about 7 ohms, and...

When I pull up on the choke, the butterflies close and it idles higher. Push the choke down, the butterflies open, and it idles lower. This makes no sense to me. As a side note, the bike already idles too high (4500-5000) so I know the carbs need tuned bad. I’m just confused as to how...

I finally got my 78 to start after changing the oil and cleaning the carbs (and properly hooking up the fuel line, I put it on the wrong inlet(?) on the carb). Only thing is it idles too high, like 4500-5000 RPM high. The rubber boots from the carbs to the engine are pretty cracked and I...

I just bought a 78 that doesn’t run. All the electric stuff up front has been pulled off and disconnected. There’s no cover for the battery box. So in the spirit of trying to see what’s wrong, I slapped in a new battery, plug in (where I hope to be) the fuel line to the carbs, and using that old...
