Default had valve float this whole time lol

changed out my stock springs for the 918's yesterday. i thought i had some valve float because in the upper rpm's around 90mph it would kinda studder just a LITTLE then catch back on and sound fine. you could actually feel the power drop off whenever it would fart on me. it would also do something weird in the 1/2 shift sometimes. it felt like i would hit the rev limiter before the shift but were certain it wasnt the rev limiter. so far there have been no farts and the 1/2 shift has been solid! theres gotta be atleast a tenth more in it just getting rid of that rev limited 1-2 shift a had going for me. it seemed to do that every time at the track and only every once in a while on the street. i guess the 26" slicks just let me wrap those rpm's up quicker and made it worse.

How many miles did you have on the stock springs? Those 918's will fix the problem for sure, I went with the PRC duals just because.
