Hi Loz, I had a 750ss before the 998 and, like the sport, it had non-adjustable forks. The rear was adjustable for comp & rebound as well as pre-load. I found the forks far too hard as standard and, as I couldnt afford to replace them, had some much lighter fork oil fitted, but I hardly noticed the difference
When it came to the rear end I just unwound the rebound by one click and wound up the preload by about a half an inch which totally tranformed the bike into a "proper handling" duke! Whether it has to be done in tandem with the fork oil change I dunno, but at least try winding up the preload mate. Of course a lot depends on your own weight and whether you carry a lillion much and I'm sure there are loads of guys who can give you adjustments to the nearest millimetre, but it really comes down to how YOU feel it's handling! Let us know how you get on.
