Flat spot....

[ktg1000]

I was hoping that the 6000 mile service yesterday would have ironed out a 'flat spot' which has developed in the acceleration, most noticable in second and third. Just a fraction of a second but it's certainly there...just lags a little before take off. Has anyone got any ideas on correcting this?

Is it at 3500 rpm or close by ?

[ktg1000]

Yes it's about 3000-4000rpm

Lambda sensors maybe ... do a search. I thought it was 2900-3000 rpm though.
