Got to admit Mark it's testing my understanding
Fitted an extra earth and hey presto bike running sweetly on two cylinders, warm it up and the turn it off. Then it was reluctant to start and when it did it was back on one cylinder.
Tried different HT leads and then coils, even swapping to the later type found on Multi 620s and alike, still no joy
Connected up spare ECU and attached a flying earth lead, now back running on two cyls. Decided to replace the Nemeseis Heatsink and use a standard one as this provides a better earth connection, with this swapped I fitted the ECU that had just been running it on both cylinders and now its back to running just on the rear cylinder.
Juts been checking Oil Temp ignition correction figures and injection phase and a few other parameters and they all seem as they should be.
Back to work tomorrow so will have to wait until Saturday before I look at it again, hopefully by then I will have had a few more ideas on what I can try to solve the problem.
