any ideas on this, my 99 zl 600 seems to run ratty (seems rich) but cleans up like you flick a switch when it hits 7000rpm. fuel consumption also seems to be up also. below 7000 it runs ok not like it is undriveable but doesnot sound clean. any ideas?
it is an efi sled the plugs are new and look a little dark, as far as the driveability it doesn't bog it just sounds a little ragged but when you get to 7000 the tone changes and it revs much faster and sounds much more "normal"
