On my 125B l just put in heavier compression springs to match my weight and found a shorter top-out spring, long top-out springs are needed to make intial travel more supple on air pressured forks. After that l was totally happy with them.

V4S travel control valves, correct springs for the application and somebody competent with a suspension dyno prepared to dial them in correctly. Also NO air pressure
