Details

NARAKU crankcase breather. Fits all 139QMB/QMA (GY6 engines such as Rex RS450) and Kymco four-stroke engines with 50cc capacity.
The kit simply replaces the stock oil filler plug. The hose is fixed vertically below the bodywork using the mounting material included in the kit.
Why do you need a crankcase breather? During the downward strokes of the piston inside the cylinder barrel, an overpressure builds up. This reduces performance, because the piston can no longer transfer its full force onto the crankshaft but also has to counteract the pressure in the crankcase. If the overpressure is released, the engine will rev more freely and can put more power onto the road. Furthermore, the dangerous effect of oil foaming can be prevented to the greatest possible extent so that the danger of the oil film tearing off can be drastically reduced. The same negative effect also occurs during the piston’s up- stroke, except that it’s a negative pressure that builds up and also has to be relieved.
Of course all engines already have a built-in crankcase breathing system; this is quite small though and therefore insufficient especially for higher-capacity engines with increased power.
