I can’t seem to get the chain on the sprocket properly it’s like my chain is to short.

Thanks so much for the purchase! Let me know if you have any questions along the way.

Thanks for the compliments!

Tip tricks principles...yes. However your engine is much different.

Thank you!

Here ya go: gum.co/LtpvD

Thanks, Victor!

Me too ! That would be fantastic !

I used NE brand w/o issues.

Yes, there might be some differences however will get you 90% of the way there.

Great question and appreciate it being answered. I acquired an ‘81 CB650 STD (5k miles on OD) in very good condition with it needing some adjustments made to it where the previous owner was either 4 ft tall or didn’t know what he was doing and a thorough disassembly, some cleaning especially anything at the bottom of the bike, some rust removal from the gas tank and the drive chain + sprocket (will likely end up replacing these) and very tiny pin head sized dots of rust on the mufflers and random other areas of high polish chrome including the wire spoke wheels, and there was splatter looking small areas of what appeared to be corrosion on both of the engine cover plates (high polish outward facing pieces that house the alternator/stator, gear shifter/sprocket+chain, oil pan, and whatever is in the last one, with 2 of these 4 plates having the Honda logo and referencing made in Japan) on both sides of the bike. This corrosion was elevated off of the surface of the metal similar to how a drop of water would sit in the same spot however, when I managed to remove it I was left with a stain in the clear coat that is sprayed on these specific engine cover plates. Anyways, I’m getting there and am almost done with half of the sanding. I’ve ordered the Duracoat Clear coat aerosol kit with Trustrip, full gloss sheen in the clear spray can, extra adjustable nozzle, and added UV protection option and am going to spray all of the engine covers to replace the clear coat from Honda with the super hard unbreakable unpenatrable coating from Duracoat, and that should keep it looking as if I just put down the Flitz rag 😊

Same

@@HTMR Thanks!

You need to use the starter motor of the kicker to check compression. What brand gauge are you using?

MatthewMCRepair INNOVA 3612 Compression Tester - 4 Piece Kit www.amazon.com/dp/B000EVU89I/ref=cm_sw_r_cp_apa_blYKAb3A6HHWM and I also have the remote starter switch as well! The compression tester works because of you I built a 1980 Cb750 that had sticky exhaust valves! I was thinking more revolutions from the starter huh?

Are you holding the throttle wide open?

MatthewMCRepair The engine is out of the bike on a table! I have the battery out and charged as well as the starter solenoid! At this point I'm gonna try to set up a bench starter like you have! I hate reinstall the engine just to crank it over for a true compression reading! Any help on how to set that up would be great! Nevertheless thank you for you content and your details on jobs! I've learned a lot from you!

Just apply 12V directly to the starter leads and she will spin. No need for a solenoid. Use a battery and cables to run the starter motor.

Your model is too different

This video will not work for your model.

Not sure sorry.

Yes

Should only go one way.

No, different design.

+Yohan Cho Fast forward to 19:46 and the video shows you how.

What problem are you trying to solve?

MatthewMCRepair trying to solve low compression, but I am going to rebuild the top end and do it right, I already installed a dynatek ingition and coils and rebuilt carbs on a chopper I'm rebuilding. How do I go about buying the video? I tried to follow the link but couldn't find a way to purchase the full length video!

Here is the direct link: gumroad.com/l/LtpvD

Bought the video, loving it so much, I'm getting ready to hone the cylinders, I clicked on the link but am having trouble for the size, I have a 1976 550 cb as well, do you by any chance have the sizes of the honer you bought?

Thanks for the compliments! Here is the hone I bought: amzn.to/2iDm8Du

I've seen these engines last for 30,000 mi and then some. There are too many factors to consider though.

Probably valve guide orings

+cygamer No, I don't have that video. I'd be happy to create one, just need someone to give me their engine :)

+BboyScubaSteve I use a dab of grease on a small screwdriver to install valve keepers.

This engine has electric start and I'm running jumper cables from a bike sitting off to the side. It also has a kickstarter.

Oh, thanks. I though they only put an electric start on the cb750.

I run black friday sales that is about it.

Yes.

Yes totally different.

@@HTMR Thank you!

Can you please reference a time in video? I'm assuming you mean the gasket scraper? Links are in video description.

MatthewMCRepair 32:40 the hone tool and I see the come in different grit. any recommendations would help I'm going to be doing a top end rebuild on a Yamaha xj600. also can you recommend a proper piston ring kit for reinstall? thanks

Check out this site for hones: www.brushresearch.com/ I can't recommend a piston kit other than OEM. Make sure to check ring end gap.

MatthewMCRepair will do for sure .. I appreciate you taking the time to respond as you actually alway have last 2 questions for now when I hone should I do it in step 120 240 320 or witch one should I use? and I plan on also changing the cam chain is OK turn the motor when it's disassembled... and actually if you want to email me a price on what you would charge to put my heads valves in spec after I'm done cleaning that be cool I'm in MN so not to far from you if you're in Chicago

Use a single grit. Here is a list depending on rings used: www.enginehones.com/technical.html Yes, you can turn motor over with cam chain attached, just make sure it does not jam up. You will have to "help" it along. I don't do any machine work, so you may have to look elsewhere for a valve job.

83 650?

Yes, however they are different. The valvetrain and oiling under valve cover is different. I've had a couple people buy for your model and it did help them. If you decide to purchase and it does not help you ask for a refund.

They go under the valve guides.

Thänks. Thats what I was thinking

If engine has bad valve seat o-rings, what could be the symptons?

Kinda. I've had a guy use this video on a cb400 and it was helpful to him. The components under the valve cover are slightly different.

Okey thanks for the quick reply thanks !!

If you buy the video and you feel it is not helpful for your model, just ask for a refund.

Wow ok great thanks !!

Yes, there is supposed to be valve lash at TDC on the cyl you are checking.

Gotcha, because at 18:28 you're talking about valve lash like it shouldn't be there-unless #2 isn't at TDC right there?

If the valve had no lash then that could be causing leakage.

To a battery.

What year?

MatthewMCRepair 1978

That motor is a lot different. Maybe I'll have a vid on it in the future.

Yes, someday.

MatthewMCRepair Great I’ll be waiting. Thanks for the reply.

All you need is to have #1 at TDC, then hook up the cam.

Oh, I get it now. The engine has to be at TDC *of the compression stroke* of cylinder #1 for proper timing but with no camshaft in place you just need to worry about TDC and not whether it is at compression stroke or exhaust stroke since without the camshaft in place that has no meaning.

Correct.

Jumper cables from nearby bike to starter on engine.

These days you can use portable power Banks

+Drew Brownell Drew, only if someone brings that in for service. I'd love to do a video on it, just need a motor :)

Bottom engine rebuild is in the works. I plan on doing carbs in the future.

I hope you are finishing it soon because i would buy both. I want to make a full engine rebuild on my CB550... When are you expecting to release it?

Well, engine is still under workbench. So a few months for sure. I don't have a set of carb in hand to do that video.

I've got a set of '73 500 carbs that need to be rebuilt. You could use those for making a video. Got 4 kits for the carbs also. 1 has a stuck pin in the float and pours gas all over the ground. I could ship it to you. How much would the rebuild and bench tune cost me? If you're interested. On another topic, what is the easiest and best way to replace the front fork seals? Remove the whole tube assembly from the tt or just remove the oil and unbolt the lower bolt that is on the bottom between the axle studs?

John, I can rebuild your carbs at $50 each. However, I'm slammed right now. On the fork seals, remove the whole tube assembly. Loosen the top cap first though.

What brand gauge? Throttle wide open or carbs off?

@@HTMR Autozone part 3614. I did check compression before with this tool on another engine of a suzuki GS and it showed around 150. That engine was on the bike. Now I have this cb550 engine out of the bike just like yours in the video. No carbs. The strange part is that I'm getting the same low compression on all cylinder. , Normally It would be different readings so I'm nor sure if it needs a top end rebuild. Supposedly the motor has 11k but I cant very this. What made me check compression is that the motor is not very clean and looks like it has some oil near cylinder two next to the exhaust outlet. Its' not necessarily from the head gasket but I like to make sure. Thank you

@@tjj6583 Does it have a schrader valve on the end that goes into the head?

@@HTMR yes the schrader valve is on the cylinder end but I was also using that fixed extension that came with the set I will try again without it.

120 110 100 120 compression result. Guess it needs a rebuild.

Where are you located?

right now I'm in Los Angeles .But I may be moving out of state this year just for the fun of it (I'm retired). :)

I lived in Studio City for 1.5 yrs. It was a great time. I have a 550 motor in my garage that need a full rebuild. I will get to it this year.

That's not suppose to happen..It's suppose to be mine. I've been waiting over 15 years for this. I've owned it sense 1976.

Well then ship it here, I'll fix it :)

Tensioner retracted? Using the cutout in cam sprocket to drop it the lowest. I know it is tough, but there is a way.

650 is different. What year? I'll double check.

1980

Looks like they are very similar. I'd get the service manual along with this video since some torque specs etc might be different.

Your 350F has a little bit different of a valvetrain. However, I've had people buy the video anyway and it has helped them. If it doesn't help you, ask for a refund.

+0Sirk0 I mentioned in the video that I had to prime the oil can. The first "10" pumps did not squirt anything. I put about a teaspoon in.

Good luck with that Evan.

MatthewMCRepair sarcasm

I got my CB550 for free from a guy who had it in a barn for 20 years. It is mostly complete it’s just missing the exhaust. The engine is seized, but I’m planing to rebuilding it.

Did you enter 25 in the amount box?

No I didn't. I thought $25 was the fixed price. Anyway, it works when I do that.

Thanks for the purchase and enjoy the video!

What is your question? Sometime I do not get notification of comments. Best to email me here: www.howtomotorcyclerepair.com/contact/

Ok makes sense

Must be why they call them enginecycles...

A motor is anything that creates motion, could be electric or IC. An engine is anything that converts heat to work.

@@christopherdelsordi4176 Thanks for supporting the argument! Exactly my point. Motors do not use heat to convert "something" (fuel, steam, etc.) to mechanical energy. They use "electron flow"... How silly would it sound to ask the "Tesla Guy" "Hey, What engine is in that?" LOL.

Good luck with your rebuild.

"im not an idiot" "It least".... lol did you mean "at least"?

Hey Jay, with emails going back and forth I'm sure you are good to go now :)
