hey team - still a tad new to nortons and always appreciate your kind support....
been working pretty hard on a 90% custom chop...the guy i got the pile of parts from included a boyer bransden kit - but with a dyna 3ohm dual output harley coil....
my question for you guys is a) is everything i need seen in the pic?
and b) prior to reassembling the engine, i was under the impression both cylinders would fire in parallel...but after putting the head it was clear they operate 180deg apart (right?) so...my question is - with this coil supplying spark to both plugs - and having only two contacts - how does it know to alternate spark? or does it send spark to both plugs at TDC each time? just anticipating mixing up the HT leads during install this week....
and finally c) is there a strong preference for anyone to either go positive or negative ground? i am naturally inclined to go negative ground - but for some reason brasden seams to gravitate to pos. ground.....?
any other tips would be kindly received....
ill be making my own wiring harness as well....
