Looking for just a simple spring swap! Happy with the quality of the suspension, it just bottoms too easily when jumping or riding fast over rough terrain. I'm 220lbs (vet rider) and use the YZ for Outdoor Motocross only. What would be your suggested spring rate front/rear? Stock is 0.430 Fork (and all Yamaha has listed as stiffer in the manual is a 0.440) Rear stock spring is a 4.8 The funny thing is that the sag seems to be in the ballpark. Thanks for your help!
