I changed my fork oil to the heavy SE oil and yes it did make a difference, dampened out the nose dive affect when hitting the front brakes. But ...... biggest difference, myself and several others on the site, SuperBrace. There are different brands that I've seen, I bought SuperBrace, but you could shop around. I'm just recommending a fork brace. Expensive, but cured the wobbles I get on CA highways from the rain grooves.
