don't waist your money on gold valves for rebound, just rework stock valve. Anyone who works with forks will tell you that for your 919, f4i, vfr. or similar forks. The funny thing is that racetech actually tell you this as well, even though they make money by selling rebound kits.
Just put new springs, Gold valves for comp since you already got them, tune up your rebound valves with new shims and put lighter oil.
Buy IMHO, ohlins valves is the way to go
