A wonderful good morning and greetings from Seville


I'm on my way to Morocco, and unfortunately, I noticed a unpleasant new noise yesterday after a long stretch on the motorway.

Brief preliminary explanation of the Moto.

It's a 1vj which I installed a new/old 3aj engine about 6 thousand kilometers ago, almost exactly before the start of the trip. Runs really well so far and was also surprisingly quiet in terms of noise etc.


Yesterday I wanted to do some stretches and drove on the Autobahn at a very moderate 14 degrees with a relaxed 90-110 km/h. No headwind, no extreme gradients.

In the course of this journey, a noise was added.
I always drive with earplugs, so I haven't noticed it very clearly on this trip so far.
When I arrived at the campsite and drove the last few meters to the campsite without ear plugs, I was very surprised.

Here's a video of the noise.
Engine was started cold with choke.
At the beginning it is not audible for 5-7 seconds, but then it becomes audible. A bright, unpleasant clicking/ticking.
For the last third I take out the choke.

What I also noticed on the freeway was that there was a short, maybe half-second moment of abrupt loss of power.
However, there were only 1 to 1.5 liters in the tank, and I was traveling uphill with partial load and 110km/h.

I once had a jamming/intensive longer friction with the previous engine in the 1vj, which felt significantly different/more intensive.


My situation now is as follows.

My plan was to stay in Morocco until March. I would like to know before the crossing (actually planned for the end of this week) what the noise could be and find out if I could better fix it here in Europe with the right parts, or if it's something that might also fix it in Morocco could become.

Maybe somebody is here who can Help me in Sevilla, or Know somebody who can help me in Marrokko(North)

The Bike is still running, but the noise is really not that nice...


ADD:
I checked the Bulbs yesterday, they sadly completely normal.
Also, I checked the Chain, I have 8 more "clicks".

Hello Marc,

welcome to the Hubb. Nice bike.

I watched your video, but its hard to tell whats wrong .... maybe somebody else here has an idea.

First thing I would do, is to take the engine side cover (clutch side) off and have a closer look.

All the best

Hi Marc, I listened and the only thing I wondered was valves, but then I am pretty useless with technical stuff.

It seems there's a couple of Official Yamaha places in Sevilla, and it's a great city to stay in whilst the bike is fixed.

If you continue down south for a couple of hours riding, there's a Yamaha dealer at Algeciras that I used before to replace the entire wiring loom on my XT660Z. And if it needs a day or so to fix you could use the time to visit Gibraltar.

As far as Morocco is concerned there's some OK mechanics and three warehouses full of spares at Moto Plus in Casablanca. Zagora has some good mechanics who learnt the hard way with rallies coming through.

Hope things go well and please let us know how the trip pans out.

Hi...yes hard to tell via video but I would check the following, doing the easiest things first. 1) Check valve clearances. 2)Remove cam tensioner carefully so as to try and keep the gasket in one piece and check how far it has extended as will indicate how much cam chain has stretched. Also ensure tensioner is working correctly. 3) Remove clutch cover very carefully, again to try and keep gasket in one piece and check tightness of clutch/ primary drive and balance shaft retaining nuts. The balance shaft nut coming loose in particular is a common issue.

I checked the Valves/bulbs, they are all alright and nothing was loose

On the Chain, i got 8 clicks left, so normaly thats enough.

To open the box of the clutch would be the next step, hopefully its make it without loose to much of oil, because im still on a campsite and hace nicely a small roof where i can fix the bike because of the rain.


Thanks for the tips with casablanca and algacerias, i will think about that as next step when for me its not possible to fix it by myself

here a a link to another video i make some minutes before.

Marc,

I also watched the second video, but still cant tell you what could be wrong.

But please stop running the engine, there is something seriously wrong with it.

Take the tank off first, and then you can lay the bike on its side (so not all the oil come out) and take the clutch cover off.

Sevilla is a nice place to spend some time in. But I nearly had my 1VJ stolen there in 2005, but the thief could not start it, as the electric starter did not work after a year in Africa and he got interrupted trying to kickstart it.

Listening to your latest video that is more like conrod small end/ piston slap noise im sorry to say

Totally agree, something very wrong, but really hard to tell from the video.

Clutch cover yes, and I'd also want to pull the valve cover.

How's the oil?
For future reference, holding the phone microphone close to the top of the engine, and then from right beside the clutch cover, and then the other side too, can help, otherwise it's just "a noise" coming from "down there somewhere". WE don't care about the video, but you telling us where you're holding the phone is good.
A screwdriver tip held to various areas and the handle in your ear can help isolate noise to an area.

Get it to a shop asap. I would personally definitely fix it before Morocco. Morocco experts may disagree.

Agree with Grant.

Pls send me a private message, as a good friend in Germany (a motorcycle mechanic with his own shop) is parting out a 3AJ/1VJ Tenere after an accident at the moment.
