Thanks Jon. I followed your advice. Engine is now much quieter. I bought my '81 CB900C 4-years ago with just under 12,000-miles. I've only added about 500-miles. Now retired and planning to use it much more.

just done this wow what a difference! my engine now doesn't sound like something is trying escape! great video

excellent Jon. I have the very same bike in the garage. Will be doing the procedure this weekend.

Interesting. I just grabbed a kz440 Ltd 1982... for my wife while I'm still on full strip down of the 1981 Kz1000Ltd... I guess I'll get to the cam tensioners soon enough... Thanks for the inspiration and keep on trucking!

John, I just aquired a cb 900 custom from my father in laws estate. Looking at replacing all fluids, hosed etc. Thanks for videos.

To all: I've got a clean 1982 CB900C Custom for sale. Looks identical to what is pictured in the video except my cylinders are black. I am in the Columbus Ohio area. Message back here if interested.

Love your channel..very informative..

So maybe I missed it in the video, but how do you know when it’s at the correct tightness? Typically you measure the slack but since this is an internal chain I don’t think you can do that lol

I have a CB900C and I love the forward controls you have on the featured bike. Who makes them? I need this in my life!

Hi, I’ve got a 1981 750C and I’m did the adjustment or at least I think I did I pretty much ended up backing them like all the way out it feels like and it helped a little I also did this while running so that might play a part? I would like to do it again ur way should I tighten them all the way back down?

Just found your channel. Subbed. Some time ago I saw a version of this job where the engine is running while doing the adjustment with the acorn nuts. Is that a valid method?

Hello, Jon I recently got my 1980 cb750 running again and noticed that the cam chain tensioner bolt is leaking. After some research I found out there is a O-ring on the bolt for the exhaust side of the engine. But I cannot find an exact answer on how to replace the O-ring. Would I be able to just loosen up the locking nut and completely remove the bolt replace the O-ring and put back together?

Hi Jon. I have a cb 900 Bol'dor from 1981. Haynes manual tell me to adjust cam chain while engine running, but it also tell me that in owners manual it can be recomanded to do it in a differet way- I think with engine not running. I don't have owners manual...Do You have any idea what I have to do, and what is the difference? - Thank You

Hello, i have an 81 cb900c and it seems to have no vacuum leaks or any carb issues. After I ride about ten miles and it gets warm I pull the clutch in to stop and it revs bad around 3,500rpm. I have read it could be a clutch adjustment issue or timing advance, my cables are all fine also. Would you have any idea what this might be? Thank you.

Just purchased the 1980 cb900c off of AutoTrader. The gentleman had a whole garage full of restored vintage bikes and seem to have a really good reputation. I rode the bikes for about an hour just one time and it was pretty hot out so I don't know if it has anything to do with that but I just noticed that it's leaking oil. Can anyone give me any advice?
