Torch a knife to remove a zip-tie was a great tip. Very useful video overall! Stuff like this is golden for the next guy.

[@Legion6139]

I may be late to the party, but my 05 FMX 650 makes exactly that sound when its cold, once its heated up she stops that and starts ripping like she should. thanks for this good information, ill keep this stuff in mind once i finally get to do it!

[@one_terrabike3151]

This is a phenomenal video! I plan on releasing a video similar to this shortly but you definitely have better shortcuts and edits 😂. The bolt removal is the worst part IMO 😂. Thanks for posting!

[@NNKH2]

Thanks! I appreciate the feedback. and yeah I tried to keep it as short and to the point as possible

[@beryean1366]

Thank you for the video. Its better than the instructions on the manuel

[@Cyberviper8]

I’m doing this right now. I feel like the cam could have been slightly off but I’m not for certain on the tdc the lobes were straight up, the sprocket lines were not straight with the engine. Looks for absolute answers.

[@ctrlz4439]

I wish I would have used red loctite as you recommended. I used blue thread locker. It seems one of bolts had came loose and now chain sprocket is only partly attached to camshaft with one badly damaged screw. All compartment is full with steel shavings, engine does not work as timing chain has jumped off sprocket. Thank you for the video.

[@NNKH2]

Damn, That's rough man sorry to hear. I'm surprised it came out with blue locksight on there. Did you torque it to spec?

[@xjbobbin82]

Great video! Well done.

[@hakandemircan7856]

Hello, should the ignition be in T position when the piston is at the top?

[@matthewwaldrip9836]

Reinstalling my camshaft the XR650L, there is about 1-2 mm of play in the thrust axis of the camshaft, i.e. I can wiggle it between the locating dowel pins. Is this normal, and if not, any idea of some things to check? Love your videos, extremely helpful!

[@NNKH2]

I couldn't say for 100% sure, but yes I would imagine a touch of play is normal there. It's possible if you look through the engine specifications for engine rebuild that you might be able to find a spec. And awesome, glad to hear that the videos were helpful

[@slppissa]

I have important news for you. the noice that engine has on cold start coming from the oil pump steel line t's the oil pump gear touching the steel tube oil transporting to the crank side

[@thatxrguy9051]

Hey I got same issue happening with my xr right now I'll post video but right exhaust valve has tons of play

Which holes did you weld both or only one? And what about the presses in dowel pins?

Thank You for the very informative video!!!! 👍👍👍✌️

[@NNKH2]

No problem! Glad you found it useful. It's a small segment from a much larger XR650L video that will be going on my main Channel.

[@mkaa05]

I’m looking at purchasing one of theses bikes. I found a 2003 xr650l with 2700.00 miles on it...looks to be in great shape. Asking price is $2800. Of what I have read so far I think a 2003 and a 2021 are pretty much the exact same bike other than color or graphics, is this correct? New 2021 models are $6999 list price if you can find one...

[@NNKH2]

Nice. They are great bikes. And yeah if anything the older ones are probably built better

[@mkaa05]

@@NNKH2 THANK YOU!!!

[@Josh-co7pz]

Great video. Does the tensioner touch the chain itself? Or does it sit behind the chain guide? Thanks

[@gti20vtMarcel]

It pushes against the chain guide.

[@shokzzu3573]

At 6:25, is it also possible to thighten them otherwise. I will do it your way and check the alignement again before doing so. Today i tried first gear + rear brake and another try just holding the bolt with which you can turn the motor/crankshaft. Both my ways didn't work. The camshaft keeps turning while trying to thighten the screws untill i can't reach the bolt no more (turned more than 180°). Is it normal that my tries didn't work? :/ I'm not sure if i did something wrong because the camshaft was properly aligned on installation and when turning the motor everything works fine (Cam- and crankshaft) :) My Motor: NX650 RD02 1992 New camchain incl. sprockets + new piston/cylinder

[@shokzzu3573]

I think the chain is not placed properly in the bottom of the motor 😕 I can turn the camshaft sprocket -> obviously the timing is off now, checked it today

[@one_terrabike3151]

Actually what you're encountering is fairly normal! Put a 17mm socket onto the shaft where you turn the engine over and hold it as you torque down the cam socket bolts. Let me know how that works 👌😁

[@one_terrabike3151]

@@shokzzu3573 Also here's a trick for getting that chain back onto the lower sprocket. Use a long thin wire that's very straight (or anything comparable...it just needs to be quite sturdy and not bend easy) and stick it down to where the lower sprocket is...a light will be helpful in letting you see it...just take your wire and push the chain back onto the sprocket and once it's on make sure you have a wire or something to keep the tension temporarily. Alternatively, you could remove the right case cover (side with clutch plates) and access the lower sprocket super easy 👍. Best of luck!

[@shokzzu3573]

@@one_terrabike3151 Well, i just removed the camshaft and tensioner again. Then i placed the chain from above and kept light tension on it while assembling everything again, so that it stays in place 👍 But thanks for the advice :)

[@stevecummings8588]

Did it only make the noise once? Mine makes a noise similar to that but it does it randomly and once when it's shut off. Im thinking it has to do with the decompresser but i haven't tore it apart yet.

[@NNKH2]

I did a full video on it. No it actually had a couple noises going on

Hi, thanks for the video, great help. One question please, what happens when you dont leave the chain on the cam gear and you dont leave the cam gear on the cam?

[@DOCTORHONDA]

excelente video!

thanks!

[@farh11111]

I tried adjusting the valves, not sure what I did wrong, could you help please: I set TDC exactly on the line next to T, all 4 valves adjusted perfectly, but when engine turns on, loud sound of loose valves comes out. Do I have to set the Exhaust valves set on F mark and intakes valves on T mark? Any thoughts/ Thank you!

[@NNKH2]

Make sure that the decompression is disengaged. Rotate the engine over when you have the caps off also and check at various intervals if there's any play. My guess would be that you miss properly adjust the front exhaust valve that has the decompression mechanism on it

[@farh11111]

@@NNKH2 yes that was the reason. It’s good now. Thank you so much!

[@NNKH2]

Glad to hear you got it squared away. And no problem!

[@thatxrguy9051]

Can I move decomp without removing cover

[@NNKH2]

I'm not sure I understand your question. The cover has to be removed to take the decompression out

Hi, I have the same problem on my Honda NX500 Dominator. This motorcycle does not have a manual decompressor. Is it possible to repair the original automatic decompressor on the cam? Wouldn't it help to replace the 3 springs or rollers of the part closer to the chain? I've already changed the part of the decompressor under which the spring is embedded in the cam, but it didn't help. Here is a video with the engine running and I think the sound is exactly the same: kzbin.info/www/bejne/pYqViH-PabWBe9k

[@NNKH2]

I think the best bet is to get a manual decomp or new OEM cam assy. Did you happen to see the Full video I did on this bike? There is a Link in Description. That has a touch more info

[@zlatan5578]

@@NNKH2 But Honda NX500 Dominator does not have a manual decompressor. Will the engine start without problems after removing the automatic decompressor from the camshaft?

[@NNKH2]

@@zlatan5578 Yea. You can add one with some slight machining. They start but not great without it.

[@yafois988]

What is your opinion on using. roller rocker arm and roller cam profile on this engine? For street I can't see it really being a worth while swapout VS costs and performance gains, for the cam though rollers are more efficient efficient. The R-rocker arms always a good idea regardless cam profile.

[@NNKH2]

I don't personally think it's needed. These engines are extremely reliable as they are

[@NNKH2]

Do they sell a roller rocker setup for this? Kind of cool if they do.

[@NNKH2]

It's also more parts to break. The bearings in the rollers can get worn out overtime. I see that a lot on the Chrysler 3.6 engine
