stuttering busa

[bioDog]

I had a similar problem where my bike would surge at light constant throttle settings in top gear, it was really annoying whilst cruising, but still had full acceleration. I added a smartTRE even though mine is an unrestricted model. Difference was immediate.

I tried that after reading previous posts of yours but its still there. It has been dyno tuned since this started but only slightly reduced it. it also has been recently serviced.

After a bit more research Im leaning towards as someone said the injectors or apparently there is a small screen in the fuel pump assembly that can become dirty and cause similar problem.

Thanks for your input, I suppose its a matter of trial until I can pinpoint the problem.
