@mrslow: thank you very much for this link, great information, exactly what I have been looking for. Cheers.

Update: Shortly after my last post, I contacted Race Tech and had a discussion with a tech who appeared to understand my issues. Sent the fork legs to Race Tech and just got them back. The valves were re-worked (no details), 0.70 kg/mm springs were changed to 0.80 kg/mm, pre-load set at 15 mm and 5 wt fluid was used. Seals and bushings were replaced. So far I've put about 100 miles on the new fork legs. There is an improvement, not huge but definite. Whereas before I was constantly reminded of the forks' stiffness over virtually any bump in the road, now I mainly just forget about the fork action. The jarring shock to my arms and shoulders is almost completely gone. The dampening and springing are both firm, and rebound dampening is still marginal but I can live with it. So, overall, I'm pleased with the change and I plan to keep the bike, which had not been an option previously, that's how much I disliked the original forks.

Hi Brock, Thank you very much for your note. Actually, I have backed off the preload front and back a bit but not noticing any real difference. I just got a shop manual, will check the recommended settings to see where the settings on my bike are now and then follow your suggestions for softening the preload. BTW, the shop manual does not offer any useful information on troubleshooting without the factory tools, except for the level of fluid in the forks. Doesn't even identify the fork oil viscosity, just recommends Yamaha's fork oil product. I mounted a little deflector on top of the stock windscreen and am happy with its effectiveness, it removed the buffeting. Again, thanks for your suggestions and comments. Lars

So, I'm three months and about 6,000 miles into ownership of a new 2022 Tracer 9 GT. Great bike, except for the suspension, IMHO. First a short pre-amble: I've been riding for more than 55 years, raced both on and off road, instructed professionally with a race school for almost 30 years, have owned more than 50 bikes, including brand new in the last few years a KTM 690 Duke, a Ducati Multistrada V2S and a BMW F900XR before getting this Yamaha. My annual average is about 15,000 miles. So, I'm far from a rookie motorcyclist. The Tracer 9 GT is a really nice bike, except for the suspension, specifically the dampening. Compression dampening is much too stiff, very harsh in fact, and rebound dampening is too soft, front and rear for both. Perhaps this is specific to my bike because I read many reviews about how wonderful the semi-active suspension is - not so in my opinion. Spring rates are fine, changing the electronic settings accomplishes no discernible difference. I've talked with the service personnel at my local dealer. They are nice folks but understand next to nothing about suspension technology. Contacted the Yamaha corporate office in California, same response. Contacted KYB USA, nobody there claim to have any idea of this semi-active technology and referred me to KYB's Japanese web site, good luck trying to find anything of use there. So, I have a few questions: 1. Does anybody else have similar experiences with the KYB semi-active suspension? Or is everybody happy and thrilled with the semi-active technology? 2. Does anybody know anything about possible re-booting the suspension ECU? Or how to make adjustments to the suspension ECU, which is located behind the left fairing panel? 3. Has anybody converted their KYB semi-active suspension to conventional RaceTech Gold Valve or Ohlins suspensions? In closing, this is a big enough issue for me that if I can't fix it, the bike will be gone. My 1976 Moto Guzzi and my 11 year old Triumph Tiger with Ohlins are both more comfortable than this Yamaha.
