2015 GSX1250FA juddering on overun?
Hi
I am finding my new GSX1250FA judders noticeably when I chop the throttle ,with the clutch out, at slower speeds.
Say around 50kmh in second and you close the throttle it slows down a bit then seems to judder.
Does the 1250FA have that overrun thing in the clutch?
Or is it more likely to be fueling issues on overrun?
Thanks
Richard

Pretty sure there is no slipper clutch on the FA.

Chain adjusted properly ? ( drive chain lash ) if not that try Gus's suggestion or a throttle body sync.

It's the lean condition the 1250 in stock trim is saddled with.
It will be worse when hot and particularly bad after the bike has been parked and restarted when hot.
A throttle balance and TPS adjustment will cure most of it but in some ways it's a side effect of a very torquey low revving motor. A slack chain will make it seem worse but in my opinion the Suzuki chain specs are too tight.

Get rid of the secondary throttle plates. My bike doesn't do this at all
