This time I will share a little knowledge with all of you about the part of the sperpart head
First I will explain the cause of the damage in the camshaft or RRA, the main cause of damage to the camshaft is definitely caused by a lack of engine oil because the camshaft really needs lubricant or oil, because it rotates according to engine speed, because this is a very part of the engine oil. sensitive, all motorbikes, if the engine oil has been dry, it is certain that the camshaft will be disturbed by the work system.
Because there are two parts that can make a sound that is not pleasant to hear, so be careful when using a 4 stroke motorbike.
The main part that causes harsh sounds is the left and right parts of the lava when both lava are damaged, your motorbike will automatically make a sound like iron friction without lubrication even though the motor has been replaced with new oil.
the second is in the axle, which is working as a regulator of the valve opening, if the protrusion of the axle is eroded, the motorbike has a lot of problems starting from unstable compression, such as when we walk the motorbike will be difficult and the motorbike cannot reach the top RPM, the most dangerous is the motor will lose compression, if the compression is gone then your motorbike cannot start at all even though the engine oil is enough,
The camshaft above has experienced things as I explained above, although it is not too severe, the problem now is that the camshaft has been wrapped in oil crust because this motorbike has often experienced oil dryness, the second in the lava part has been shaking badly so the motor will feel vibrating and sound like metal friction without lubrication.
The valve trigger now can still be used even though it is a little dirty caused by oil, oil is again oil again, I never get tired of reminding all of my friends, REMEMBER OIL REMEMBER SAFETY FRIENDS, ok back to the initial explanation, earlier about the valve trigger already pretty clear, right, we go to the springs, the springs, there is no damage if you look at them but without us knowing all these springs can no longer be used because the compressive power is gone, not everyone knows this because to Checking the compressive power per valve requires a special tool, so here I immediately declare that the valve can no longer be used because I checked it using a tool that I borrowed from my repair shop friend.
What is the cause if the power per valve has decreased but is still reinstalled?
Yes, it is certain that the compression will leak because the spring cannot press the valve itself perfectly, so if the motorbike is installed there will be an explosion when the motor is on an incline and most likely the motor will die.
Ouch !!!!!!! The radiator hoses are like this dough-like dough sudah this motorbike is complete with the suffering he has experienced, until it breaks like this, this motorbike is rich not only used by the owner but is abysmally abisan I'm sure, this is the first problem I have encountered in 6 years I worked in the garage, ok without thinking about the problems experienced by this motorbike I immediately explained the cause of this messy radiator hose.
The obvious cause is the radiator water that dries too often without being noticed at all, or a leaky part of the hose connector,
The second cause is the part of the radiator coolant that is clogged or clogged,
The third cause is that there is a loose part of the joint connector which means that the radiator water is wasted
Or it could be that the water used does not support the performance of the radiator so that the water dries too quickly and does not work optimally,
After I looked for the cause of the leaky hose and in the end I found the cause which was very fatal to occur,
The cause of this hose is in the leaky head gasket so that when in the combustion chamber, the wind that should come out through the 100% exhaust exits through the head gasket gap and then goes to the radiator path, just order the radiator hose until it's like cookie dough.
The piston handlebar is shaking badly, the skewer bolts are still safe and the full pump air radiator that has been damaged, the internal parts are also damaged due to leakage of the head gasket so that the effect of compression combustion pushing into the radiator pump,
The timing rollers are also broken, yes, if the timing rollers are used to it, it's not only in motorbikes that are not properly maintained that can break even in motorbikes that get more maintenance they often break because the motor is not always in the lower RMP
On the wall of the gasket there have also been blisters caused by amateur mechanics, because most mechanics are not careful in removing the gasket, without them realizing that when the gasket wall is uneven there is a high chance that the oil will come out so easily that it will pile up like oil crust. .
That's all the explanation from me
