hi have you changed the coils as i had this sort of misfire that caused a judder

as going up the gears off the start line on my race nc23

good luck dave

Is it an after market exhaist. Could just need setting up on a dyno if so.
Check wheels are balanced.
Also do you have in bar ends?

I would take Mikiboy's advice. After market exhaust. Check if you have 4 pipes going into 2, then into 2 - that is the correct configuration. If you have 4 pipes that go straight into 1 then that is a cheapo after-market exhaust and you will get a flat spot when you try to accelerate which will pick up after a second or two. Only solution is a new exhaust.

i have the same problem had it since i got the bike and i have tried everything but nothing works
so i just get use to it lol or i dont let it get to the point were it judders i just give it full throttle to get past it quick lol
but my judder goes on for ages if im doin slow speeds and yeah in every gear
