Well, the bad news is that all stock NSRs are basically rooted. Stock **** suspension, old saggy springs, and a setup aimed at little Jap teenagers rather than Aussies who've had a bit much beer (not the designs fault, you see how much your bits sag in 20 years )

There is hope though! Try and set your rider sag (plenty of guides all over the net) and see what that tells you. It'll probably tell you that it's basically sacked out and needs a little suspension love. This is good though! Springs are cheap and easy to fit (well maybe not easy on the back but you'll manage).

Won't make up for the deficiencies in the dampening mind, but one problem at a time. Don't even both dicking about with the geometry without fixing those fundamental flaws first.
