Improving Compression Machine

Increasing the compression ratio (Compretion Ratio = CR) is a way of beginning to be taken by the mechanics to increase engine power. However, to increase the compression ratio to consider several factors, among others:

     Fuel used.
     Quality piston used.

How to increase COMPRESSION 1:

     Replace the piston with model racing / forged pistons.
     Bringing the deck clearance.
     Head lathe.
     Weld Head.
     Block and Piston lathe.

How to increase COMPRESSION 2:

     Trimming head or often called the cops, make it easier to take it to the turner to be more careful in trimming. trimming head usually no more than 5mm. in this job you have to exstra carefully because if there is a possibility seker miscalculation you will be damaged by too much trimming.
     Porting suction and exhaust holes, which enlarge the diameter of the hole so that the incoming fuel mixture volume becomes more plentiful. The easiest way is to use a drill, but the result is less neat and smooth. if you want to get maximum Performance motor then you should be careful in doing research.
     Noken lathe, which is cut into shorter Noken to open and close the valve to be faster, but the effect is the sound of the engine will be a little noisy due Noken into loss.

HOW TO LOWER COMPRESSION:

     Merimer dome on the head.
     Deepening coakan valve on the piston.
     Piston lathe.

The positive effects of using high compression:

     Motor power becomes larger
     Final gear becomes heavy.
     Power engine feels from the bottom up lap.

The negative effects of using high compression:

     Sounds a bit rough engine
     Fast heat engine
     Engine break it rough
     If the calculation is not precise compression, frequent detonation.
