Fork springs - cutting them makes them stiffer, no need for aftermarket springs?

[Lumpy]

Lumpy,
Are you saying that as dual rate the FZS600's springs are linear, not progressive and the mod would not be effective for them?
I haven't altered my FZS600's springs, but obtained dual-rate springs from a 94-97 VFR750 & removed a few of the tighter coils; the mod works perfectly for me with about 112mm of suspension travel being used up without resorting to stoppies.  From memory the VFR springs were virtually the same overall length as the FZS springs to start with.
Then again, my forks are no longer standard so I can't test theory out.

more an if, I've not had mine out yet although I have to change the oil soon, I hate to think what it looks like. I think fazers were fitted with linear springs on some and progressive on others so no idea what's in mine. I always prefer linear personally and to go up 2.5 weight on the oil and play with air gaps. Being a lard arse and riding quite hard the standard set up is surprisingly good.
