I have an '03 zx6r 636. I've been experiencing a couple problems: I noticed a grinding or raddling noise coming from the clutch on take off. And not really sure if this is a problem but, I've noticed on start up it runs a little slugish but then idles up after a few seconds. Not sure what cause's this but I always have to start it with the choke on, and it takes a few seconds for it to idle up. It does have a power commanderIII, and not really sure how it is programed(purchased from someone else). any help would be great.
