fare enough, the pulsar ones a good cheap fix but for what i've spent/spending on the engine i'm going to hold out for a bosch unit. going for high reving and plenty of fuel to burn i'd like the stronger spark the next issue what coil to run with it ???? been told by the auto elec to stay clear of those little high energy coils and stick with the standard oil cooled high energy, less chance of it over heating and breaking down with high revs ??
