Naraku racing CDI problems

So if you gona buy a CDI, be warned that it might not have the same strong spark as your old CDI.
This CDI only worked if gapped below normal, i should add that the engine had 14-15 bar compression with a 70cc bbk, so thats one of the reason for the poor performance, but the fact remains, Stock CDI gives me much stronger spark.
Well, its not all bad tho, with a weak spark you have a less chance burning down the coil, beacause very strong spark = dead coil.
