Bore up car is a good component to check.
When we recently replaced the Valve stem seal during the Overhaul, we also replaced the exhaust Valve Stem.
Why? →Valve on the exhaust side is bright white and slightly GizaGiza................this looks bad (lol).
What symptoms did you have?
?Many stalls while driving.
No ?Idling.
I have not been able to improve the above even after ?Carburetor setting.
?Black smoke is now coming out of the Exhaust System.
[Cause?
Carbon adherence to Valve
↓
●●* Insufficient fuel in lean Burn region
↓
Insufficient cooling
↓
Carbon ignites (Detonation)
↓
Valve erosion
Lean Burn ... lean combustion. 。 In the case of gasoline engines, the ratio of air to fuel that is just right for combustion is called the theoretical air-fuel ratio (14.7 to 1), and if it is thinner than that, the Lean." The name of the product is called
→The possible reason is that when I initially bore up to 75cc, I was turning the carburetor setting quite a bit with the carburetor setting thin.
What is Valve Stem in Engine?
Valve Stem is related to Engine, and the axis of intake/exhaust valve formed by the umbrella and the Stem part is called "Quantity:The term refers to the bearing portion that is set.
Valve stem seals can be used to prevent engine oil leakage.
Where is the Engine valve?
Engine valves are installed at the intake and exhaust ports, and like valves in the heart, they are constantly opening and closing to control air inflow and exhaust gas discharge.
Simply put, it's like a doorway or door to the combustion chamber. 。 It is such an important component that it is not an exaggeration to say that it determines the performance of the Engine, and the reason why there is a limit to the number of revolutions of the Engine is because the Valve cannot keep up with the revolutions.
If you compare the engine to the heart, the engine valve is a valve-like component inside the heart. 。
Valve Replacement Method Same as with Stem Seal.
procedure
?Remove the Dynamo cover to expose the Flywheel. Similarly, remove the Side cover of the Cylinder head.
↓
(2) Match the notch on the Crankcase with the top dead center mark (T) of the Flywheel and the 0Mark on the Camshaft Sprocket with the notch on the Cylinder head.
Remove the locker arm, take the camshaft, remove the Valve Spring using the ValveSpring compressor, and remove the Stem Seal→.
Remove the Valve Stem and replace it with a new one.
After installation, do not forget to adjust the tappet clearance using a Thickness Gauge and Tappet Adjust Wrench.
The following is the sequence of assembly:?→?→?.
In my case, I found a damaged Valve Stem when I replaced the Stem Seal.
Stem seal replacement and valve stem cleaning or replacement are done at the same time.
The exhaust valve was available from POSH, but it was for the Big Fin Head Bore Up Kit, so it was NG.
OEM.
[After exchange]
◎Idling is good.
◎Stalling while driving was eliminated.
◎Black smoke also disappeared.
Regardless of the Engine Displacement Volume, if you bore up with the Normal head, the high RPM range and Main jet should be a slightly thicker number.
I don't want them to have to struggle and go the long way like I did (laughs).

Genuine Honda Gasket for Cylinder on CBR125R 2012
This bike definitely needed a new gasket as the previous owner just did not keep up with maintenance at all. This bike has done a lot of miles in it's life with it being a 125cc anyway. Not a big deal, I found the correct part number from Honda schematics etc. Webike price was really competitive too. A few other parts with this were ordered together by EMS and delivered in 5 days. All my order was delivered with no issues, all the gaskets were kept flat so not to damage. This gasket is not a big one but it does have some intricate details that need to be correct to fit the cylinder. You can see it has been manufacturered the right way and not cheaped out on it. It is sturdy and has a slight flexibility. All the holes aligned with the fitment and went on pretty easily too. Fitted quickly but precisely in just under an hour with everything else put back together. Very pleased with this one, the bike does sound a lot better and I know it will last a fair few years to come. Thanks Webike. View detail

OEM replacements
This product is a great the OEM. With the help of youtube how to videos the installation was very straight forward. I did have some question on what was needed to install the valves and the online chat room answered all my question.Installed these with the springs as well, after the initial break in, maybe 4 hours, Haven't had to adjust the valves for about 40 hours and counting.Hold up great in a highly built 4 stroke engine that takes a lot of abuse. Highly recommend. View detail
