Power cutting at higher rev range

Postby tim » Wed Dec 22, 2021 7:22 am

Hi all,

On a ride on the weekend the 08 zx6r was cutting out/down on power when:

under load, and
hot, and
into the higher rev range (started loss at around 8k, dead above 10k)

Does happily rev in neutral.

Thinking to first clean the fuel pump/pickup filter.
Next replace plugs (hasn't been done in years)
Clean injectors?
Throttle bodies?
PC3 getting hot and failing?

Any thoughts?

Cheers,
Tim.

Yep, all the above..
Sounds like a fuel blockage or pump issue.
Maybe try a different map on the PC or remove it see if that is an issue.

also...

cant hurt and cheap as, to run some decent injector cleaner through the bike, but i had exactly the same prob on a recent GSXR600 i fixed up, put a $120 fuel pump kit through it, went hard after that, i still reakon the injector cleaner helped.
Pinched or bend fuel line that bends more when hot?

just throwing a few out there.

Thanks guys! Haven't got back to it yet, but yeah fuel line is a possibility (I did have the tank up refitting some parts) and will try some injector cleaner.

I did a fuel pump kit 2 years ago - this one

not sure on the quality.

Will update

I had the same issue on a ZX7 that was due to the battery. I replaced it and all good!
