ESTRELLA's Crying Place
I started Restore of ESTRELLA, which was immobilized after I stopped riding it.
I was looking for the cause of the problem I felt at the time I was riding and was concerned about the restoration of the engine.
One of the causes we considered and replaced was the Piston ring.
[Piston ring]
Simply put, it is the Seal of compressed Gas.
The Piston ring acts as a seal when compressing the fuel/air mixture inside the Engine's Cylinder. 。 This maintains the pressure in the combustion chamber and keeps the Engine's Power.
Why did you think it was a Piston ring? ◆Why did you think of Piston ring?
*Looks like it's going up Oil.
Oil is running high...White smoke from the exhaust system while driving and engine oil is running low.
This is a symptom of oil wear→ Oil leaking from the gap between the Piston and Cylinder. Then, it is possible that the Oil leaks to the outside.
Here, we replaced it with an OEM product, not a low-priced external product, etc.
Piston ring replacement procedure
(1) Remove the cylinder head.
If you drop the Camshaft Chain down, you will have to lower it below the waist, so it is better to hang it with a needle gold with tension.

(2) Remove the Ring of the Stopper with radio pliers and pull out the Piston Pin.
↓
(3) After the Clip is removed, press the inside Pin from the inside to easily pull it out and remove the Piston. 。
(4) Take out the old ring. It is deformed rather than chipped.
(5) Ring is correctly set to Quantity.:Set and Install 。 The order is ExpanderRing → top and bottom SteelRail→ Top ring→ SecondRing.
? Simply assemble in reverse order.
[After exchange]
White smoke from the Exhaust System is gone.
It seems that the Oil uplift was the right way to look at it.
However, the oil leakage does not seem to have stopped.
I would like to start on the next part.
The clearance between the cylinder and piston is very small (around 0.1mm), but this small gap makes it impossible to compress the air mixture and receive combustion pressure without loss.
It seems that there are many cases of malfunctions in ESTRELLA's Initial Model (90's), and one of them is oil leakage.
Initial Model's Piston ring is thin and has low strength.
If you suspect oil leakage as well as oil rise, you should consider replacement.
Oil leaks have not gone away yet, so next we will look at the Camshaft Chain Tensioner.

Great piston for the price
I have never been led astray on any yamaha oem part and when it came time to split the cases for a bottom end rebuild I added the oem piston kit (does require case split to install the oil sprayer). Immediate power and torque gains throughout with negligible rev impact.webike offers it at the best price. Shipping and packaging is great. Webike is too fast View detail
