Hello,got this bike a while back,I know it was running,but it has been standing in a yard for ayear or so.Decided to chop it down and rewire it due to knackered components,so did so as per a diagram found at tom yehya racing.No spark at all.Tried a second hand black box from a vfr400,no success.The wiring I'm sure is correct and makes sense,are there any other problems these bikes tend to suffer from?The pickups check out for continuity as do the coils.I'm a bit flummoxed.I'm thinking of trying to make a CDI from scratch to a diagram for an old H2 Kawasaki,found at Lakeside.com,has anyone else done this,or found any other (cheapish)solution,I ain't got much money,thanks. gavinsaunders3@yahoo.com
probably missing an earth connection somewhere, Guvna. you checked or by-passed the "run-off" switch at right handgrip ??
