Strange sounds in 4-stroke motorcycle engines could be a sign of damage. However, not all the 'noise' means the damage. There is a motor that is positioned within the maximum clearance between the metal, so noisy. Here the engine is often the cause of the noise of the engine.
1 valve
The sound of 'tick-tick' or 'tuk-tuk' light indicates when the machine is stationary valve setting tenuous, so the rocker arm hitting the valve head. Increasingly loud sound when the elevated gas rounds. In addition, as a weak valve, causing the same sound.
Sounds like 'tok-tok' probably due to the rubber 'shucks' (located between the cam chain tensioner with) wear out, then pushed up against the end of the cam chain tensioner. Chain cam is too tight also cause noise or hum suing. While the sound 'sek-sek' continuously, usually gear or cam chain replaced requested.
In the sector of the combustion chamber, the sound is very minimal. Symptoms piston or piston ring wear, barely audible. Easy to know if the motor power is reduced and white smoke out of the exhaust. If the knocking sound started to sound a little heavy, a sign of piston seek redress.
Rattling noise sometimes appears in the lower rounds to the middle rounds fade away at the top. This voice emerged from the foot / handlebar piston slapping the cylinder wall when the bottom dead point. Beware of this sound by checking the condition of the engine.
What if buzzing occurs when the motor is turned on? It could mean a worn piston start because the piston pin does not stick to fit in his house. When the piston condition is severe, the louder the sound.
6 Bearing Piston
Same conditions will occur when metal bearing seat and the metal crankshaft wear. Usually accompanied by the sound of 'ker-ker' harsh and heavy beats. Not to forget the increased engine vibration at Footstep and handlebars. Preventing reads crankshaft, piston change following metal bearing seat and running.

Homes clutch problems contributed not sound pleasing to the ear. Beep 'srek-srek' continuously or 'thump' when the motor is braked suddenly clutch wear can be caused or automatic system began to thin.
