Hallo Mark, coole Tour .hoffe du kommst gut nach Hause.
Mein Tip von meiner Domi Erfahrung zu deinem Geräusch sind die Ventilsitze. Wenn Sie heiß ist löst, sich als einer und dann kleppert das Ventil. Wenn sie abkühlt dann sitzt er wieder fest. Die werden heiß eingepresst und mit den Jahren heben die nicht mehr. so war es bei mir. Mal Tage lang nichts und dann denkst du die fällt gleich auseinander.
Bin gespannt auf die Ursache.
Grüße und tolle Abenteuer!!

Well… Good luck to get home with the "broken" bike… But… Im disaponited…
So… You couldnt finish your travel through Portugal… But you will risk a 3000 kms on a "broken" bike going home?!?!

Check the motor oil!!

Sound like a valve has broken …! Béchir from tunisia

i think sounds like.tyming chains

Hi Marc but how many km does this bike have?

Spain, an amazing country for ride a bike

Sounds to me like a valve seat came loose. Ist a common problem . It Cracks from the sparkplug thread to the valve seat, then the seat comes loose when hot. When it cools down againits tight again till it heats up again.

There are road signs that you are not paying attention to so the road clearly permits vehicles.

If you can’t find a place to get your motor fixed properly the ship the bike home and you take a train or bus. Get your bike fixed by someone who has some proper skills then start out again with a properly running motor.

You need a mechanic who is willing to thoroughly investigate. Check the cam , lifters, tappers, adjustments, chain tensioner find out if it’s in the top or bottom end.

Hi Marc, was the tensioner full extended? If so, replace the timing chain in any medium size motorcycle shop. You don't have to go to Berlin just because of that. I belive that sound is either valves or timing chain. Keep up with the good videos and good luck.

Take skid pan off , keep it slightly cooler

Just going to throw this out there; it could be an air / exhaust leak. A very small gap has opened up and as you ride, it may cause the noise or, it may seal up eliminating the noise. Check where the exhaust headers mount to the cylinder and any other joints along the exhaust (if any.) Who knows, you may have already solved the issue by the time you read this. Good luck. Cheers 🇨🇦

I would suggest checking out Montoro, it's not far 🙂

Hope it all works out with the Honda such a nice bike

You worry too much and you don't enjoy the trip! I had a Dominator and it also sounded like that, it could be the timing chain, or the tensioner or chain guide but the bike works fine but with noise…don't worry so much and enjoy!!! Peace and love my friend!!! ;))

Hi! here is a Spaniard who has found your videos on YouTube. It's curious, it gives me the feeling that you are exploring space, the difference in language makes everything different and more solitary. If you need help with places or mechanics don't hesitate to ask, good luck!

Hey Marc. I live in the UK and am always looking forward to watching your videos and getting inspired for my own next bike road trip. Not heard from you for a few days. You ok out there?

Alter Falter, sorry wegen meiner harschen Worte, ich meine es nur gut 😉. Du hast üble Geräusche am Motor, vermutlich der Steuerkettenspanner, also kann der Motor komplett kaputt gehen, die Folgen wären somit im günstigsten Fall ein totaler Motorschaden, im schlimmsten Fall ein Abflug im Nirgendwo,, aber dir sind 4-5 Tage zu teuer? Frag doch mal in der HU oder Tet Gruppe oder anderen Gruppen nach Möglichkeiten zum reparieren und übernachten. Anstatt Mails zu schreiben, hätte ich das Moped gar nicht in die Garage gefahren, sondern wäre direkt zur Werkstatt. Wünsche dir auf jedenfall alles Gute! Das Video ist ja schon ein paar Tage alt, hoffe euch beiden geht es gut! 👍🏻

Hört sich nach Steuerkette an oder ein Lager was im Motor aufgegeben hat. Und wenn es abgekühlt ist, hat sich alles wieder soweit zusammen gezogen, dass es passt. Aber wenn sie warm wird wird es schlechter und schlechter. Denke eine gute Idee ist es nicht damit auf eigener Achse bis Berlin zu fahren. Ein Pick up wäre besser. Gibt's da nicht eine Möglichkeit den größten Teil per Auszug zu machen?

Perhaps the same problem https://youtu.be/WKS7p8XE_x4

Marc. good luck on getting home – check this out – intermittent problem -Tapping noise XR650L https://www.youtube.com/watch?v=X-b9s9a12RU
If you get back to Berlin ok perhaps its better to buy a spare dominator engine.

your valves hting broken valves springs maybe take the cover off and see before u blow the g
head off

loose valve seat??

just wondered if you keep benzine in that tank on the crash bars? Being on the outside of the bars, it will probably burst and from experience, there are sparks aplenty as you slide down the road.. Will you be doing that on fire? I think it's great that you carry spare fuel, but thought I'd air my thoughts… Good luck with that ride home.

My Honda Dominator had the same trouble ! I fitted new cam chain & cam chain guides and also new cam chain tensioner spring ! Problem solved.

Hello, I am watching your trip with curiosity. I feel like I'm traveling with you. The source of the problem on your motorcycle; I think it is due to the gasket located at the junction of the engine block and the exhaust. The gasket found here must be replaced or compressed. Have a good journey.

I feel so bad for your bike problems , please next time buy the best bike brand in the world buy Yamaha and you will never have a problem believe me or almost never hehe

Reservación 🤣🤣🤣🤣🤣

Beunruhigend das shit Geräusch…das macht wirklich keinen Spass…hoffe für Dich dass es nicht noch knallt im Motor, bin auch schon länger gefahren mit sowas…nix passiert. Weiter viel Glück und alles Gute, Mark !

If you ever happen to be next to Coimbra city, you can visit "Ondacoimbra", it's the Honda dealership of that beautiful city and they are very friendly people and very professional.😃

Take your bike there for a checkup, they're awesome. 😎👍

https://www.youtube.com/watch?v=X-b9s9a12RU maybe its this problem ??

I would order up a new genuine honda cam chain, and tensioner assembly, and get it fitted locally. Also keep taking note of the noise, and see how it progresses, do not ignore if it gets significantly worse, if you decide to continue your journey. No guarantees in life, but chances are been a honda of a generation that we're over engineered you will be fine. There are some great videos on youtube of how to change the above parts. You are in a wonderful part of the world, doing what you enjoy, just enjoy the whole experience. You have already met some great people because of the mechanical issues, that you would not have without.

cant beat a old honda i have heard them rattle like babys toy blow smoke like a steam train
and just wont stop 👍👍👍

hello Mark, how is it going? I hope that you are evolving and will be able to pursue your Journey soon. I have a question for you. I see you are using the LS2 helmet, may I ask how do you like it (or not?) I am thinking about buying one too but don't know anyone that has one. How is the visor , does it seal well for noise (isolation) or not , what you don't like about it – please tell so I can evaluate. Thank you

read on line what causes what the engine is doing. keep going and you will get stranded
what does on line manual say. .

Parase que el ruido aparece cuando el motor se calienta, suerte y muchas rutas!!!

Cam chain tensioner problem is VERY common in a lot of bikes. I had this problem myself and put in a new original Honda tensioner and had the same clacking again after a while. I ended up putting a manual cam chain tensioner instead of the original automatic. We are with you man. Keep forward, you have a great bike!

You are a champ of a great man good luck🏆🏆🏆🏆🥇🥇🥇🥇

hey man try to change the music ,sounds bad…all the rest sounds good

remove the clutch cover and see if there is an obstruction in the screen that filters the oil to the oil pump

HI, to know if a spark plug is bad, put a damp cloth on each of the exhaust pipes, if the tube is hot, the heat will evaporate the water. If nothing happens: the spark plug is blown, the spark plug HT wire is damaged, the ignition coil has a problem. Start by replacing the spark plug and visually check the condition of the cable. Good luck

What about an oil change?? And check for metal partikels in the oil

Hello
how many kilometers has the motorcycle already run.
