stuttering fzs 600

[clayt74]

hi CRH, i had a very similar problem last week, but mine stuttered at anything above 4k.
it was actually dropping a cylinder.
the prob with mine i think was 3 issues,
the well for the plug caps had wet leaves that had blown in (due to being parked up under a tree)
i also found a HT lead was a bit loose in the cap on cylinder no2
and when i took the plugs out the gaps were way too wide, cleaned and closed the gaps and it now runs better than it has in ages
