Put some Nulon Octane Boost and Clean in my tank last night and the issue has ceased, at least temporarily. Got a bit of a power increase also..... NICE. I guess all I can do is monitor it, change fuel stations (there's a Shell up the road) and occassionally use a cleaning agent like Nulon.

Dunno the setup on your bike if the pump is in the tank etc, but some have screens that can get gummed up internally.

This happens alot. Will become more evident as the bike gets hoter as the bike will lean out which further highlights the issue. Happened to me at the last round of the FX last ...

The bike isn't cutting out as such, just not getting past 7K rpm.

Did they tested the fuel pressure and not just the flow?

Is the pump running when it is suppose too?

Also make sure the correct plugs are in it and in good order.
And the error codes dont mean squat, they just lead them down the ...

Side stand switch cutting out at high revs? Try taping it up or shorting the terminals... or run the bike and go around banging different parts of the bike to see if she cuts out.....

It def seems like a fuel problem. I've been using BP Ultimate for the past 18 months, predominately from the same servo. I'm thinking of running some fuel addiditve to clean out the system. Any suggestions?

Sorry to get back onto topic, but my Z is playing up again. 7k RPM but no further. As previously mentioned, had the throttle body cleaned out, fuel line replaced, fuel pump pressure tested (was running to the book), K&N filter put in and new clutch cable (obviously unrelated).

Does anybody have any ...

Issue now sorted. Cleaned the throttle body entirely and placed a K&N filter in it. Replaced the clutch cable while he was at it (needed it). Running like a dream now. Thanks for your help.

BTW, approaching 40 but still not interested in the ZRX. And the '03 Z looks nothing like a tourer..

Thanks for the advice. Love the Z too much though..

huh?

does it rev cleanly then hit like a rev limiter? or does it struggle all the way to 7grand?

cant see an airbox being the issue, unless it blocked up?

Revs clean till around the 7K, then just struggles. My mechanic noticed a valve that when under revs closes off, located near the air box ...

Hi All,

Have an '03 Z1000 which is playing up. Can't get past 7K rpm, seems to lose compression. Thinking it might be an issue with the Air Box or solenoid. Has anybody experienced this and have a solution? Kwaka have a part to replace for around $300 that I'm trying to avoid forking out for if it ...
