f4i throttle response jerking when it engages

https://www.stuntlife.com/forums/2-s...e-kicking.html

started a link in stunt discussion and got some help but i figured i could get more here.... it seems like in the lower half of the powerband/rpm range when you let off the throttle completely.. then get back into it (no matter how smooth) it jerks when it first engages (which caus me to damn near gorilla 12 twice yesterday) anyone else notice this and how do you fix it?

I would say your chain is real loose or your rubber cush drive spacers are wore out....

Yea, what he said. Although I notice it a little with mine and both my chain and cush drive are on point

every bike is always going to have slack within the system...turning up your idle should fix your problem as long as your chain and cush drives are within spec.
