now a model racing exhaust slip-on |
The weakening performance 4-stroke racing exhaust largely due silencer is worn. Silencer hardened and unable to be a part of exhaust gas processing. Exhaust gas was no longer in the tube stop silincer but immediately discarded.
If it were so, its features other than gasoline wasteful, energy also will sontoloyo. Also sound so shrill. Its exhaust gases escape. Exhaust gas has not bergasing should and most do not return to the combustion chamber, to help re-burning. There are two major diseases can quickly lose silencer and hardened, namely:
First exhaust often take in water when washing the motor and the rainy season.
The rainy season puddles everywhere bro, like now heavy rain everywhere. Moreover puddle already passed the muzzle exhaust and engine fit in a pool of dead water easily sucked. Water will tighten the pores of the damper when it dries instantly as a result of the heat engine.
The second is oil.
Well, many misguided. He said 4-stroke exhaust must be preserved with oil filling. Yes it is for a standard exhaust can, but do not let the racing silencer. Oil pressed fiber oil will glasswoll and eventually harden.
glasswoll is still good |
Be careful also for engine oil leak through combustion. For example, a torn valve seals or piston rings are already weak. Now the oil will be discharged through the exhaust. Yes, it must be absorbed by the damper. As a result, the exhaust gas will not bertubulensi silincer again on the tube, but not directly into the atmosphere.
