As you will know i have a CBR600 and when its warmed up the idle is very erratic, it smells like its running rich and also its a cow to start when hot....


Now as i know nowt about 4 strokes any advice on setting carbs up so the mixture is right and also getting the other problems sorted will be muchly apprecaited :)

if its got seperate k&ns on it then it might of been upjetted in the carbs as well locate the mixture screws and turn them right in untill they just nip up then turn them all out 1 1/2 turns for basic settng

If you haven't already done so, I would check the ignition system out first.


My last bike had a split in one of the the HT caps & was shorting out to the plug hole, causing a misfire on one cylinder & the revs to hunt slightly.

My last and current CBR600F's do not like starting when they have a hot engine believe me!


But the erratic revving at temperature is odd... When you say erratic how so?


Could just need plugs as that cured the problem with the land ladies car recently :)
