07 ZX6R , stutter at 4000 rpm , any one have this prob?
I have a 07 ZX6R, with around 7000 miles.
Mods are akropovic slip on , k&n filter, power commander, jumper mod.
I currently have the bike at a local shop that dyno tunes motorcycles.
The problem is that we are discovering a stumble/stutter at 4000 rpm - 4500 rpm then it goes away.
As you accelerate through the spot it does'nt occur, it only shows up when you decelerate through the spot then come back to 4000rpm.
On the wide band, it goes completely lean between 4000 - 4500 then comes right back were it should be.
The guy that is tuning the bike for me also has a customer with the same bike as mine that is experiancing the excact same thing.
Guess my question is..........Is this an inherant thing with the 07 ZX6R? , or is there anyone that has came up with an fix for this?
The guy that is tuning this for me, said that he was going to try and adjust the throttle position sensor and hope that it solves this prob? Will this work?
Thanks for any helpful info,
