Brock Buttars at Brockstar Suspension did my KYB's on my Yamaha. Brock was the only person I found that would actually take the time to explain exactly what he does to make them "work right."
I used to race ITA, F-Prod, Honda Challenge cars, so I know enough about suspension to have a decently informed conversation. I couldn't find any other suspension company that said anything other than, "send em in and I'll make them right."
Side note: I have 3 days on the new setup and they are absolutely amazing. Plush in the top of the stroke, ride nice and high in the stroke and came nowhere close to bottoming out. I believe Brock set them up with a .60 spring and then worked his magic on the slow and mid valving stacks. He is also very reasonably priced and a really nice guy to deal with.
