NARAKU CDI ignition unit without rev limiter for Fever ZXII, KB50, Heroism, Curio models and SYM with standing cylinder (double plug CDI). For throttling or simply alternatively as a cheap replacement part for the original CDI, which unfortunately very often has defects and can be quite expensive with a price of about 100,-EUR. All tuners will be pleased, because until now there was no way to completely dethrottle the E2 models of the Fever ZXII. The ignition curve is the same as the original ignition curve, only the rev limiter is removed. To be used on all Fever ZXII models (Euro1 / Euro2), Kymco / Meteorite KB50 and Heroism 50. Also fits on the last series 1999-2000 Kymco Fever KCA. Please compare the CDI installed on the vehicle with the product photo. ATTENTION: To unthrottle the vehicle you must also use a racing sleeve from Kymco or Naraku!AI-translation
