1 x Crankcase Breather Silver for 139QMA/QMB engines
Component No: NK100-10
Colour : Silver

The Naraku crankcase exhaust is suitable for use on all 139QMA/QMB and GY6 engines. The kit simply attaches to the oil filler plug and is fixed vertically on the underside of the bodywork.

So why use this modification, simply really, due to the small size of these engines the piston creates enough resistance on the downward motion to restrict performance. Using this kit pressure is relived from the crankcase case and allows the piston to travel more freely during its downward stroke. A quick simple modification that can give you that little bit extra!
