Mysterious misfire

[taksi]

Many thanks Falcon. Looked at the link and then bought 4 coils from e-bay for £100 quid. Sorted. Multimeter readings all ok but I suppose they're not under load conditions then. Process of elimination nailed down no2 coil so now I have three spares. Still, I'll recognise the symptoms straight away next time and any new knowledge is always a bonus. Still disappointed it has failed at 12,340 miles though, thought they'd last longer than that. Looking through that link it seems to be a regular occurance and something maybe Yamaha should be looking at.
Thanks once again, buddy
