CLOSE OUT SPECIAL!!! Get 2 for the price of one!!! If you have YuanDong SkyHawk engines made prior to 2014 you need these puppies! We will no longer stock these early models after present stock is gone. All Black; This module is a SD BenTeng brand manufactured CDI; Marked YD on underside and some are marked BT on the underside. SD is the oldest CDI manufacture and was the OEM supplier to BenTang and YuanDong engine factories up until in or about the year of 2015. When you hear someone say stock CDI you must know what factory made the stock CDI because they are not all made with the same timing. NOTE: You must use a SD CDI with a SD mfg. rotor and magneto coil match to get correct timing with 25-degree crankshaft. To understand "why daddy" go to grubeeinc.com information side and read all about 2 stroke Ignition. It is very important that the 2 brands of CDI's do not get mixed up due to timing variances. WARNING: This is the biggest problem 2 strokes are experiencing. Show more
