Hi all, I'm having trouble getting the ignition timing correct on my '81 CB750C. It's firing way too early but I cannot retard it any further since I've turned the plate all the way already. What other adjustments can I make to resolve this? Thanks. Video of it running...

I bought this swingarm bearing kit for my CB750C but it didn't fit. The models listed are for '79 K and F but I think it should fit the rest of the gen2 years. It comes with 4 needle bearings which replace the brass bushings, a new collar and 2 dust caps. $100 plus shipping.

Thanks AMC. I should've been more specific with my question. I don't have access to the original harness so I can't tell which wire connected to which connector. Do you know which is the upper left, upper right, bottom left, and bottom right connectors? Would the circuit issues result because...

Hi all, I'm rewiring my '81 CB750C. I just got to the starter solenoid, which I assume is the original, OEM unit. I see the 4 male connectors go to the reg/rec, starter switch, ignition switch, and clutch diode but I'm unable to find out which one is which. Is there a way to test them? Does...

Thanks to all you wonderful people on this forum I've finally rebuilt my engine. I was super methodical to ensure I didn't make any more mistakes upon reassembly. Now that it's all together there are a couple issues I'd like your help addressing. First, the camshaft sprocket marks refused to...

Thanks AMC. I took the retainer back off and backed out the bearing on that side slightly. It seems to have loosened everything up so the opposite bearing now moves freely, the spacer moves, and the bearing that I backed out moves but it feels a lumpy. Does this mean the balls pressed...

Hi all, I have a couple bearing questions. I just installed my new steering stem bearings and I cant seem to get them seated all the way. I have the motion pro steering stem bearing driver and I'm whacking it as hard as possible but it won't go that final mm. What should I do? Should I freeze it...

Much better! Thanks AMC! I went with your pacing and it looks good to me..

Hi guys, I just tried to hone my cylinders but I wasn't getting 45 degree cross hatching so I stopped. It looks flatter, closer to 120 degrees. Why is that? Am I not moving the hone in and out fast enough? Or is the drill spinning too fast? Before...

Thanks for the advice guys. @AMC are these the ones you were talking about? https://www.harborfreight.com/12-piece-precision-needle-file-set-4614.html

Hi all, I'm about to reassemble my engine and I nicked up the base gasket surface. Should I use sealant in my specific case? I have some Hondabond but I was told its only for metal to metal surfaces? I also have the right stuff which I was told not to use with gaskets. Should get some gasgacinch...

Thanks AMC!

Hi all, I removed the alternator cover to polish it and "brush B" seems to have snapped off. What does it do? It seems like a switch or a button but I'm not sure. Is it sufficient to super glue it back on or do I need to replace it? Thanks.

hi all, is there a strong argument for either rebuilding or replacing the OEM brake master cylinder on my cb750 DOHC? Thanks.
