KYB SSS Set up
I just had my KYB SSS forks re-valved by a reputable tuner. He swapped the .42kg springs for .46kg springs.
First ride on re-valved forks last weekend and I am not utilizing all of the fork's travel. The forks are not wiping the last 2-3 inches on the tubes. The forks are harsh in the slower, rocky sections and on square edges. Oil volume is now 355 cc, whereas I was running 325cc per leg before the re-valve. I am 180lb without gear. It seems that based on my weight I should be at about a .44kg spring rate. Can anyone running KYB's chime in on the spring rates and oil level? Also, any issues with running one .42kg spring in one leg, and a .46kg in the other to bring me to .44kg total spring rate? |

I was experiencing the same. I went to expansion-tanks and opened up my compression, which helped dramatically.

I'm around 77kgs, and I have .45kg/mm and 22Nm ICS springs. With .46kg/mm springs they were too stiff, and even now I think I could either drop to .44 or probably more likely use 20Nm ICS springs.
Only running around 315ml of oil in the outer chambers, but also using a tight float valving setup which also impacts on how quickly you can get through the travel too. I use quite a bit of my travel, but never really bottom them. Given that you paid a tuner to set them up for you, they'd be the person to talk to though. The fork as a whole works as an accumulation of individual aspects. You need to consider the whole, and that will depend on what approach the tuner has taken to determine the best way to address the issues. |

No issue with running different springs in each leg either. That's how I'm setup at the moment.
1 x .44 and 1 x .46 for an average of .45kg/mm |

RockefellaGG, please could you post some details and photos of your expansion tanks.
Thanks, Harry |

I just did this conversion 2 months ago for my 07. I bought the whole 06 YZ450F front end, sent the forks to LTR, asked him to revalve for mostly rocks/roots but to build in some bottoming resistance if possible. He pulled it off, and I love the setup now. I am 180# without gear, he put a .44 fork spring in, 325cc of 5wt oil. I haven't checked the oil height yet. Les told me to please give him feedback if I needed changes, but I don't think I do.
The KYB SSS eats up the rough stuff *almost* as good as my Zokes did, but I don't bottom out on jumps or drop offs now, and can pound the whoops like Ricky Carmichael. OK, OK, not quite like him, and yes, they are much smaller whoops, but I am more confident with these forks for sure.
