control unit/ECU/CDI from NARAKU, unthrottled with matching intake hose for Euro4 50cc 4-stroke Yamaha, MBK from year of manufacture 2018. The CDI does not have a speed limit, so the engine can be completely dethrottled and the entire speed band can be used (it may be necessary to use additional chokes, e.g. of variomatic). There's nothing in the way of tuning cylinders and racing exhaust. This NARAKU ignition box can be exchanged immediately plug-and-play for the original CDI and can of course also be used as a spare part.
