loss of power

[taksi]

Went over to SMC Sheffield last week and gave them an hour at it. Had a good chat with the techie afterwards and apart from one throttle body out of sync, couldn't find anything else. He also supected coils even though the readings were ok. Bought 4 used FZ1 coils on e-bay for £100 and fitted them yesterday - all hunky dory. Back to my lock up and swapped the old ones one at a time and road tested after each change. No2 was the culprit so I could have saved myself £75 but hey-ho I now have three spares and have understood some new symptoms for the future.

Many thanks Dek for the info.
