Does anyone have any experience with a G2 Throttle tamer? It is supposed to ease the initial throttle inputs on a twitchy or hyper sensitive motorcycle throttle.
The reason- I want to get a 954rr as a stunt bike but they do have moderately twitchy throttles. I was thinking about throwing a G2 Throttle tamer on it to make slow stuff easier.

Question #1 > Has anyone installed or used a G2 Throttle tamer?
Question #2 > Has anyone installed or used a Rev2 Throttle kit (it allows you to change out reels to essentially have a quick or slow turn throttle depending on the reel size)

I thought this would really help for throttle control when doing stunts especially at low speed with a literbike.

Also I was wondering if a tune can make throttle response smoother.

End goal is to make a (or any) powerful bike have a very controllable and smooth throttle response. Any insights or advice on how to achieve that would be great. Thanks in advance!
