sparkplug change on fz1s gen2.

[AyJay]

If you have all the AIS gubbins on the bike, access is tight but taking the radiator off isn't really necessary. But here's a thought - I only changed my plugs after 50,000 miles and I wouldn't have changed them at all if it wasn't for the salt corrosion at the tops, they were all fine ... healthy gap, virtually no erosion, and no difference in performance or starting after the change at all.
