Sorry Stephen, it was the CDI box, i did electronics and am quite competent, what is true is that the spark plug leads do eventually stuff up, but because they are moulded into the coil you can't easily change them.
Here's a 100% solution tested out by me, i used a holden VR-VY coil, then bought 2 new leads, the thing runs beautifuly, now i can change the leads without having to buy the whole lot from yamaha.
