Assuming you have already maxed out the preload and compression/rebound, the next step would be swapping out springs and maybe going to a heavier weight fluid.

Might just be time to service your suspension.

VFR in general has a crappy suspension

so your best bet other then cranking the rear to full hard

is to replace the rear shock and ft springs.

i had the ft done up on mine, when i had her, made a world of difference.

Up the spring rate. Compression and rebound adjustements are designed firstly to keep the contact patch of the tires in consistent contact with the track/road surface. If you try to get "stiffness" from upping a compression setting, you only get a tire that bounces up off of bumps and is constantly varying it's contact patch and adhesion level. Going to thicker fluid has the same effect. Unless you're planning on riding on perfectly smooth roads only, too stiff on the compression/rebound gets dangerous. You'd be very very surprised how "soft" those setting are sometimes on race bikes depending on the track and conditions. I've seen a lot of street bikes adjusted "stiffer" than I'd go on a race bike - everyone thinks that stiff=race. What IS frequently different on race bikes VS street is the rate - race apps usually use higer spring rates. The springs on the VFRs are set up closer to comfy sport touring for 150 pound riders than for sporty rides for 227.

Depending on the miles, you may want to freshen the shock and forks at the same time. If the shock still has a good charge in it and isn't leaking, then I'd at least put bushings and oil & dust seals in the forks since you'll have to open them up anyway to put the springs in and change the oil/check level. I just went through the front end on my Duc last month and rebuilt the forks and added Racetech G2-R gold valves in them. Your year VFR800 uses the same valve kit that the Showa forks in my Duc (S2040). I like the Racetech stuff. I've had 3 bikes I've put their valves and springs in, and done 3 or 4 other race and street bikes with them as well. Great for the money.

Racetech sells springs for the '03 VFR800 as well as valve kits. A set of fork springs will run about $110 plus SH and the rear is about the same. Info follows:
FRSP S3732110 springs in the forks and an SESP 802250850 spring on the shock. The fork spings listed are 1.1 kg/mm and the shock spring is 15.2 kg/mm. Both of these are noticeably higher rate than the stockers, but aren't "race hard."
