I have an 02 SV, and weigh 175lbs. I know what you speak of in the "mushy" front end.
You need a few things, and you will be setup.
First lets go with the super easy way,
Cost: 400-450 bucks
Contact: Traxxion Dynamics
Product: They will set your front forks up with a set up racetech gold valve emulators, and custom damping rods, new springs, and new fork oil. Also they will replacee your fork seals if needed.
Easy way, but a lil bit harder
Cost: 200-400 bucks
Product: Still contact Traxxion and get there damping rod and emulator drop ins. This is the same product thta you get from them, however you do the work, so you save the money. You still have to provide the new springs, and oil. And if you dont have a couple of tools it will be cheaper to have them do it.
The difference in having them do it and you doing it is simple. If you do it, you know its done right, and now you knwo how to rip your fork apart and do the work/service on it yourself. If they do it all you do is pull them off the bike, bubblewrap them, ship, then reverse the order to put back on.
Either way I think its the best setup for SV's that I have ever used. Others will dissagree, but you know what they say about opinions....
