Hahah you do know what NOS stands for yeah?

Side note on a related topic, I'm installing a custom cb550 harness that a friend got from sparck. We are using accel coils with a dyna pulse. I can't find any black/white wires to connect with the coils. How do I get power to the coils this case? I'm only seeing white kill switch Y connection...

Need a good left fork from an '81 750K Custom. Prefer buying this fork lower alone if possible to keep shipping down. '81 750F forks in black would work as well, but I would need a matching set. Not interested in any other years 750 at the moment. Got '79 750F forks and K8 forks but really...

xb33bsa, thanks again, my buddy will be happy its not blow by, I didn't think that it was. Once your carb floats are all good and you've got the right air/fuel mixture, I would get new plugs, gap them, then do your timing with strobe. Carb sync should be the last step after everything else is...

Not stuck, just trying to find out what some of symptoms are. As mentioned a friend thinks he's got blow by happening but no white smoke. He said he found fuel or oil in the exhaust.

What kind of evidence at the breather would show in blow by? Like some oil and gas mixture leaking?

Hey xb33bsa, do you know any obvious indicators of blow by? A friend suspects that he's got it on his 550. Very interested in this thread as I've got a 73 350G in the ranks waiting to get restored. Black smoke is supposed to indicate over rich fuel mixture but could the stuck valves be what's...

I heard that using a vacuum gauge on each cylinder can isolate a stuck valve. xb33bsa great tips, glad you are on this thread, cheers. Wondering if you have any other general suggestions for valve jobs and diagnoses.

Not too sure how to diagnose it while running. I know that white smoke is an indicator. I've heard that holding a stethoscope to the engine can help to hear what's going on but you'd have to know what to listen for.

back firing could be a sign of being too lean yes. Could also be stuck valves or valve seals not in sealing anymore. or in the worst case, piston blow by. My 550 fired up like new as soon as I replaced the points with nos tec points. You're getting a lot of solid advice. I would do spark plugs...

Someone needs to relax. I have a full time job. And I've got them NOS. Take your meds bro.

headers... no holes, no pitting.

Should have your cable if you're still looking. Cheers

I've got a couple but they are original new old stock.
