Completely screwed

[AdieR]

IIRC Kawasaki had problems with failed ECUs on early ER6's due to positioning, which was duly modified by the factory on the later ones; can't remember if they were subject to any recall though.

ECU's should last the lifetime of the bike; I'll be checking mine shortly when I put the new tax on it.

Let us know what you get back from Yamaha.
