Oil in water xciting 500

[xsel777]

Yep, and for that I am very grateful (no Netflix ads).
Now the talk is about using the original head gasket.
I have voiced the opinion that the engineers messed up, as there is no other place I can think of that works be causing white smoke from exhaust except combustible chamber area.
The head does not have water channels, as far as I know, so only at the gasket area where coolant can be introduced into the exhaust causing white smoke.
I wonder what is on netflix?

Well Folks. I am on the road again.
However......
lol, you didn't think it a going to be that easy right?


It is smoking heavily.
Since I got it back, yesturday, I have had to put 1.5l oil in.
There were actual smoke rings leaving the exhaust when revving on the stand.

I am disappointed that the shop did not investigate the smoke which I mentioned three times,Each time it came back from the shop. I did say it was white smoke though.
Still it still warranted investigation.
And the shop owner has mentioned twice now that there is potential for smoking if the barrel is removed.

Luckily now, Yamaha, the new agents actually have spares in Durban, 1700km away.

So, now I am riding with a litre of oil in the top box.

What is right :
Starts first time.
No coolant leaking or spewing out.
Temp stays at half.
No engine light(newish O2 sensor)
Original gasket seems to have done the job.
I wonder if it is because it has that thick bulge around the cylinder hole, which the copper gasket did not.
The scooter is raring to go fast. I can feel it definately has got the power back.
Higher compression is the reason.

Ok, I have just paid for rings, another head gasket, tappet cover gasket. 2 days eta.

I tried to complain but it was waved aside, I don't think I was heard.

Very disappointed.

The new mechanic says he just needs to hone the cylinder, and regular size rings will be fine.
The excessive smoke can only be coming via the rings he says.

This thing has reached a point where it is no longer about the money, but about my peace.
I saw milky green antifreeze coolant in the return pipe(right under the filler cap), so it is starting  again.

I cannot comprehend what the actual issue is, because the head and barrel were skimmed, the copper gasket showed a coolant leak. Now the original gasket is showing an oil into coolant leak.

How can this be happening on an ongoing basis.?
It makes zero sense.
I know they are trying their best.

Apologies re the rant.
There is no other platform I can let rip, as in nobody else in my circle is mechanically  inclined, so I just get blank stares, and from my wife, daggers, because this dang scooter is no joy.

Yes, this is nutz. I maybe way off base and way out of line but cannot help myself: different mechanic, get one.

It IS terrifically aggravating not to have a reliable daily ride.
Goodness, you have tried so hard!
Makes me embarrassed to be upset again this morning about my LIKE's one mirror that won't stay in place. All 4 of my scooters have been bullet proof (or made so after just one warranty fix)
Can't imagine constantly having to approach my scooter and wondering if it will work this time....especially after so many repair attempts.

We're all pulling for you!...but you know that.

Righto, this is the situation currently:
New oil  rings were rattling around in their slot.
Verdict was piston is worn.
So that is now ordered.

It is confirmed that no oil leaked in to the coolant.
Very good
Very VERY good!
The oil was found on top of the piston.

However, there are hammer marks on the upper face of the barrel.

I told the owner I am not happy about this as that is not how it came back from the engineers.
He would not take responsibility or acknowledge any wrongdoing , and just stated he will double check it later.

I took photos.

Your "mechanics" are UNBELIEVEABLE!

Amazingly, the piston arrived overnight.
I hurried over to the "mechanics", and got them to fit the new oil rings to the new piston, and they did that and it looked tight, and then they showed me how secure it was in the barrel, so that looks like it could mean that the high oil usage is sorted.

I left feeling somewhat reassured.

I might be riding this weekend.

I got so fed up, for awhile I stopped going over to the workshop to check on progress.

Anyways, I went over yesturday, and the scoot was out on a test run, no white smoke from exhaust (a good thing), but evaporating steam from coolant pipes splitting, this time above the oil cooler.

Today they are out searching for coolant pipes they can use to replace mine which are all weak from all the oil that has been flowing in them.

In the meanwhile more helicoils had to be used, as the engine had been disassembled so many times, I suspect  every thread now.


That's all for now.

Hang tough!
We're still following your posts with interest.

I got it back today.

What has transpired.

On the test run, the right mirror blew off.
It appears to have had a stress crack that finally gave way, evidenced by a darker colour(dirt) over most of the surface and a smaller white area where it finally gave in.

Anyways, that does  not faze me at all.

I had to go look for generic hoses, all the thin diameter ones as they are bursting all the time now.

While searching motor spare shops, a pipe burst and all the coolant escaped. I drove off the highway, 200m about, and then pushed it home.

I replaced all the perished hoses, and filled up with coolant, almost 2l.

Ran until hot, and noted oil residue in the filler neck.

No white smoke from exhaust.

I took it for a test run, and when stopping abruptly when I got to my drive way, the oil light came on momentarily.

I will check oil levels tomorrow, and take it for a long ride to see if the oil accumulates in the filler neck again.

oh boy.

Have a good week end folks.

After test drives up the freeway, a miss that I had noticed when revving while on the centre stand, suddenly became extremely apparent when it started with cutting/missing out at 130kmh and above.

When I got to a stop sign, there was massive surging  from 2000-3500, making the scooter unsafe to drive.

Workshop will collect it soon.

I went over there and mentioned that hammer indentations on the barrel (by the area where the oil is exiting and pooling on to of the engine) is not the condition the barrel was brought in, as well the previously mentioned, the hammer marks on the gasket surface, was not the condition after returning from the engineers.
I asked if this warrants me shouting in frustration, if I have valid points, or am I just a stupid customer.
This produced some  throat clearing only.

Mentioning the same issues to the mechanic produced a "deer caught in the headlights" look.

I think I shall watch some online tutorials that can improve my IT skills.

Keep well all.
