Ok so i recently busted my stock throttle and replaced it with motion pro "replacement" tube on my 03 F4i and i noticed that it is really touchy. I didn't tweak or adjust anything while switching it out but definitely is alot more twitchier. Could that just be because of the "replacement" throttle tube?

 

Yup yup. I put a 1000rr throttle tube (which I think has the same throw as the motion pro) on my f4i and it's a lot twitchier. I like it tho since the F4i is a turd, it gives more throttle response.

 

yeah i still dont understand why you did that
