Re: Cam Chain Guide 1981 CB650

Sorry for the delayed response but I was able to locate one on ebay by messaging sellers of Honda CB parts directly to see if they had any guides left in their parts bikes that they had not yet listed.

Thank you still George.

Re: Cam Chain Guide 1981 CB650

The one in your pic looks to have one square mounting point where the one in my pic are both round. tensioner blade 002.JPG George, I would still be int...

Re: Cam Chain Guide 1981 CB650

Where are you Dom? Ebay should have some listed although the prices seem to vary wildly. I do have one but I don't think it was in a very good shape, it's been a while since I've seen it, I'll check it out later. I am located out of Connecticut. Ebay has many listed for the CB550 but these aren't c...

During my current teardown I have observed the cam chain guide at the front/header side of the motor has snapped right in half! I am having a very difficult time finding a replacement. Any help is appreciated, if anyone is willing to part with a halfway decent spare, that would be tremendous. . PN: ...

Re: Need A Starter Clutch

Thank you! That should work for the internal components of the clutch. I'm hung up on whether to replace the actual clutch itself. What are the typical signs that of it needing to be replaced? The body of it has shifted so only one of the three torx bolts was able to fall out of place. With the othe...

Need A Starter Clutch

Just went through the task of removing my faulty starter clutch for my 1981 cb650 and im having a hard time locating a replacement. Anyone have any suggestions on places I could get my hands on a new one? Do clutches from the cb750's work? I'm looking at one for sale on ebay and it looks slightly di...

Re: Still need a little help....spark or fuel?

I have almost the exact same problem with my bike, it can't rev up high with a load on it. How can you make it run on a less rich mixture?

Re: 1981 Honda CB650 only firing on cylinders 1 and 2

thanks for the insight, I actually have it running on all 4 now. Low end power is good but I couldnt get it to push past around 50 mph. Probably gonna need to go through the carbs again. Maybe they're out of sync or a high speed jet is clogged.
