Nah that was the rear end playing up Damo, it knew you were behind me and kept puckering up . I've still got working antidive so I don't get too many front end problems.
And yeah I was more like 95-100 kgs back then. Plus the 9 is bigger and heavier than a 600r, but I'd imagine that Streets is potentially heavier than your wife, and maybe rides a bit harder too, no insult intended but that is generally the way of the world.
The information that I'm quoting (I've never seen the benefit of removing anti-dive so never have) is from sites like OSS and GPz900r.org where members have removed anti-dive. They also reckon that it gives the front end a wooden feeling.
