RE @ 12+58; Just my opinion only, but you did NOT waste your time painting your bike! Sweet machine and your meticulous situational awareness and "attention to 'motor sound' detail" mad skills are a tribute to your expertise and technical prowess. Indeed, a true nostalgic throwback to my '80's XR200R and XL350R kid days along Utah's Wasatch Front. Thank you for taking the time to document and post your fantastic restoration journey!

[@NoNonsenseKnowHow]

Thanks man I appreciate your encouraging words. Hopefully this video will help others with the Honda rfvc for years to come. I used to have an XR 200 as well. Great bike!

[@paulhaines5755]

I did it! Replaced mine. Bike sounds A LOT quieter. Well worth the effort. Thanks for this vid it helped a lot.

[@paulhaines5755]

I also discovered there is absolutely NO way to do this without removing the engine on a 1984 XR500R. I thought I'd post this info for others who might be researching this job.

I just tried this drilling a hole in the head , for a bolt to act as a mechanical tensioner you show at 6min30sec. It seems to have worked so far for me on a Honda NX650 Dominator 1999 (almost same engine) . Thanks for the idea!

Thanks. Yeah they are great bikes for sure!

[@bluejack644]

As tuff as this bike looks I'm taken aback that the video only has 1K likes. Especially considering it has been posted for 1 year. I've been seeing lots of videos lately featuring fully restored Honda XR's & XL's. As well as some pristine originals, (Kaplan Cycles). And don't get me wrong, I'd love to have one, as would we all. But this bike here looks rugged and ready. It's off road experience shows. It's been there and back many times. Counted many coup. Lived many lives. I like it, it's got sand. Character. It has a marvelous persona. Not to say that it looks beat up, neglected or abused. Because it doesn't. It looks slick. But it also looks like it was used as it should have been. Loved, but used, and not in a bad way.

[@kenspomer8494]

thank you for the idea, I used a right angle attachement for my drill and within about 5 minutes i had a manual chain tensioner that completely solved my issue! I just used your drilled hole as a reference

[@NoNonsenseKnowHow]

Wow! I'm so happy to hear that worked for you. I haven't actually used the manual adjustment mod yet. I just put it there for future use. But you just made my day. Thanks for the confirmation that the idea will work! Did you run a tap to thread the hole? It didn't seem to me that there would be enough meat there for it to hold long-term. I feel like it would eventually work loose

[@paulhaines5755]

Great vid! My XR500R sounds EXACTLY the same. You can actually see the pin (the part you have sealed with right stuff) oscillating on mine to match the noise. If I put a crescent wrench on it I can rotate it and the sound gets a little less. I rebuilt the engine on mine a couple years ago but failed to replace these parts. I wish I would have! Too bad the engine's gotta come out... I ordered the parts and I'm gonna tackle this soon. I hate to pull the motor but it's not that big of a deal I guess + I can clean it well. Thanks again for the great video!

On my xbr500 from 1987 I can just lift the valve cover when I pull of my fuel tank... Don't need to remove the complete engine, maybe it's the same with yours, with some luck...

[@paulhaines5755]

Just finished this job on my 1984 XR500. The engine has to come out I found out. There are two long valve cover bolts on the top that will not clear the frame with engine in bike. Well worth the effort, though! It's sounds like a new bike, now. Tight... Really awesome improvement. Now I just gotta figure out why it burns off some oil when you start it after it's sat for a while. Do you have advice? Is it a leaky check valve on the oil pump?

[@paulhaines5755]

Oops - I replied to this vid two years ago then just did again with kinda the same comments! I think I'm losing it...

Great video, really clear and helpful. Couple of questions: 1. Was there any obvious sign the the old spring had weakened significantly?; 2. Any idea why the adjuster needs a clutch device within it?

[@NoNonsenseKnowHow]

Thanks David I'm glad the video was helpful. No I didn't see any sign of the spring being weakened and I'm sure it could have been reused. but thermal Cycles generally take a toll on Springs over time so I figured for how cheap it is, certainly a good idea to replace it. And yes, the Bronze bushings on the tensioner clutch had visible wear and I believe inside components also had wear if you were to compare them to factory especially under a microscope. It did not grip the shaft as reliably as the new one. Hopefully that helps answer your questions. I wish I still had it, I would go back and maybe take it apart to check out the inner workings.

[@AndrewBrowner]

i could be wrong but i think the sprag clutch stops the tensioner from backing off after its applied tension, it can only advance it cant back off, if it was just the spring pushing on the cam chain it could possibly push that spring and get enough slack to jump a tooth

Also see I have the bearing behind the sprocket on the cam shaft the other way around, thought it was meant to 'be in the oil bath'... Runs with 1 kick when warm. 2 or 3 when cold.....

Hi. Nice video with most of the answers I've been looking for. One thing I can't understand is how to install the cylinder head cover. When I try to, the rocker arms (I think this is their name) are falling and I can't get them to stay on to valve head. What's the key to that? Thank you!

[@bardinkurtis]

I'm having a hard time getting the timing set correctly or understanding how to do it properly. Im new to this and still learning. I have a better understanding of how this works but damage may already be done. I had to replace my cylinder, piston, and rings. Didn't set proper tdc before removing anything. I set my timing just with lining up my T and not worrying about TDC compression. My question is prior to installing cam shaft in correct position with lobes facing down sprocket sitting correctly with the chain on how can I find true tdc? Will my valve's still move when rotating engine? So basically just the piston alone moving up and down should be able to tell me what stroke I'm on by observing the valves correct?

[@NoNonsenseKnowHow]

If you didn't position the crankshaft at top dead center before installing the cam then take it back apart. The only way to know that the piston is at top dead center is by the viewing port on the magneto side to see the t mark. Or you could also use a top dead center finding tool if there wasn't a mark.

[@NoNonsenseKnowHow]

Set the crank to top dead center and then time the camshaft so that the little notches are flat with the cylinder head surface.

@@NoNonsenseKnowHow Thanks, i will record a start from cold to warm soon, maybe u can take listen when u have time to spare.

Hey man, I decided to use your method of manual tesioner, but I first soldered a little bit in the area so I could have more thread and make it stronger. But I was wondering, should it screw it tight to the tensioner? or leave a bit of room? I don't know if the tensioner actually go back a bit on high RPM or if it should stay in position, I don't want to put my chain under a lot of stress. Thanks for the awesome idea.

Same problem here. Question: what happens if you ignore it?? Thanks

[@JuanJimenez-mj7uh]

Hi, from Spain, great job. I bought a Dominator 650 (same engine that your bike) a month ago and I can hear a noise very similar. I was wonder if it is possible replace only the spring or its necessary replace the three parts (tensioner, spring and o-ring). How can I know if the tensioner is broken or doesn't work well. And my last question... How can I know if the problem is the timing chain? How can I check it up?... Thanks a lot!!!!

[@NoNonsenseKnowHow]

Hey, thanks man. And honestly it's hard to say without actually hearing the noise in person. I would recommend replacing the tensioner spring and o-ring to start.

No problem! Good luck getting her fixed

I have a 83 xl 600r has oil leaking a little out the left exhaust port.i put new exhaust rings ING its still blowing a little oil out and can hear some ticking,maybe lifters need adjusting ??

[@NoNonsenseKnowHow]

If it's leaking oil out of the exhaust port then it's probably bad valve seals. Or might need guides as well

[@grantdowling8960]

@@NoNonsenseKnowHow if I have to rebuild top end then should I replace all seals and piston rings and any worn rocker arms or cam shaft,

Very nice work! Enjoyed watching! Can you teach me how to keep my work shop as Clean as your! 😆

[@NoNonsenseKnowHow]

Thanks Roger. And I can assure you it's not always this clean! I made sure to tidy up before turning the camera on! lol. But yeah overall I keep it pretty organized. Unless I'm knee-deep in a project and it gets bad

[@jarguedas]

Great video, thanks for that. But how could you drill a hole in your engine and put a bolt like that?!!

[@NoNonsenseKnowHow]

No problem man. And LOL I'm surprised you the first person to mention it! I was a little skeptical of doing it. But if it starts making noise in the future I didn't want to have to pull the engine again. Now that I have that tapped hole on the back I can easily correct any noise from a faulty tensioner in the future.

[@bardinkurtis]

Because he's a baaaaaaaad man!!! Thanks for the video!

[@robinsongguitars]

How is the performance (low end, mid range or top end increase/decrease) with the XRs Only header? Noticed the little hole on top of the cam chain tensioner was a little left of top center. This is an indicator of the stretch of the cam chain. The farther left of top center the more stretch. New chains will have the hole pretty much at top center or just a couple of degrees to the left. Nice job.

[@geewhiz6818]

I have ticking and since you've tackled both the decompression and the timing chain tensioner- can you shed some light on how to identify which is which? When your buddys bike had decompression issues, when you reved up, did the ticking go away? On your bike with the timing chain tensioner issue, was it only present after warm up- then always there? I have 13k and mine ticks bad at idle. Seems to away when revving.

[@EDP1]

i had same problem and the garage did use the same solution like you did.noise was back after one week. you also need to check the heads off the valve's.and replace them.cause when the timing belt was not properly adjusted, the head of the valve's are also a little worn out and thats where the tikking sound comes from. it shows in your video, the heads off the valve's are not chining.with head i mean the side where the springs are.

[@NoNonsenseKnowHow]

I've been riding mine quite a bit and no issues since this repair. What's the mileage on your engine? I should have mentioned in the video that it would be a good idea to replace the timing chain set as well, but I wanted to see if the tensioner was the main culprit. In this case it was.

[@NoNonsenseKnowHow]

I'm not sure I understand your whole statement though due to the typos and you said timing belt. It does not have a belt

[@EDP1]

@@NoNonsenseKnowHow sorry about my poor englich.i mean offcourse the timing chain.if you hear for 14 days nothing it solved.incase it comes back check the valve.i dont have a bike no more.

[@NoNonsenseKnowHow]

@@EDP1 okay. I appreciate the input, I'll definitely keep that in mind if the noise comes back. Was it the valve stem to guide clearance that was the problem? Or what about the valve was making noise

[@EDP1]

@@NoNonsenseKnowHow cause the timing chain was off .the valve knocks a little deeper on the head of the valve.that make a little ruf surface.you can see it in your video.heads are not smooth.there are some dark spots in the middle off the valve ontop.

[@AndrewBrowner]

i had very similar issues on my 02 DRZ400, ignored it and the tensioner failed and let the valves meet the piston, was a completely different tensioner design and is pretty common failure... new piston valves gaskets and i drilled the tensioner out and tapped it to 3/8 npt and used a carriage bolt and lock nut to tension it.. trouble is i need to pull the fuel tank valve cover and a pile of other things to check the cam chain tension to retighten it but atleast i know it cant fail enough to skip a tooth this time

[@frankmiranda1352]

What would make the valves switch operations like blowing out into the carb and out the air filter
