2003 ZX6R Running badly

[Huambo81a]

Just happened today,

I took it out about 30 minutes ago and shortly in to the ride it started running badly at low revs, hard to explain, kind of a juddering sound, as soon as i had the revs high and wasnt holding the speed at a constant rate it ran ok. Sometimes in 2nd gear i would rm the throttle on full, and it would accelerate like a 125 until it suddenly ran clear and came alive. Very odd, does it sound like Injectors?

I`ve only had it for a month so its within the six month warranty, but i hope its nothing serious.

Filled it up with fuel recently/run it on the reserve tap? Sounds like dirty fuel/blocked injectors TBH.

Hit it with a big stick.


I agree, sound like crap in the injectors. Will prolly blow through.

Sounds more like mine to me!

I have the same thing; it kind of judders; a very on/off/on/off noise, as opposed to the smooth sound. My bike isn't fuel injected either, but it does have a System 3.

It can still be a dirty batch of fuel on a carbed bike. The 800cfm carb on the Buick got choked up once through a nasty batch of fuel.

Interesting, my bike makes a "rubbing" noise whenever I accelerate even though it still accelerates at the same pace.

Got it back from the shop today, the guys said it was fixed no problem, and that his engineers took it for a test ride and thought it was an air bubble in front of the injectors which cleared up as they test rode it.

Within 2 minutes of riding out of the showroom its back, a juddering/ lurching/ unwillingness to go, until it suddenly finds power. This is serioulsy frustrating, could it be the alarm (Datatool System 3)

Whats going on!

Na like a "whoosh" "whoosh" noise. Gotta feeling it's air passing through my new oil cooler cover though.
