Dong Fang 150TKB Reverse Trike problem ?

[airboatphil]

I put my timing light over the plug wire and observed the light pattern from idle to accelaration until the miss occurs..... It is definatly in the spark going to the spark plug.... I still say I am " hitten' the rev limiter in the CDI " . I have put a new CDI but not the performance model. There is a chance that I got a bad CDI out the box but I'm still puzzled ?

thanks,
phil
