New fzs600 rider who is heavy

[sinto607276]

Thanks for the suggestion. Is it worth looking at just changing spring on the original shock or will this just ruin the damping? I have never messed with suspension before, how do i calculate what rate spring i would need?

Not worth the hassle,  you'd come across more problems stripping it down and rebuilding it as it's of an age that most internal stuff would be shot.
I'm only 11 stone and my boy who's about 9ish stone, I appreciate you say your 22, but with my boy on it, my bike feels a wee bit iffy at the back compared to when I'm on it myself, and I'll need to look into another shock at some point soon.
I certainly will be looking at a straight swap or upgrade to an R6 shock when that time arrives, too much hassle trying to go the way your thinking.
Oh, my original shock is on a 24000 mile 1998 model.
