If you're on the west side of the big smoke, you could also take the bike to Scott Miller at Fast Company in Breslau. He can set up the bike, build your engine or prep it for a superbike race. Just sayin'. 
Anyone in gta do suspension setups?

I can identify a difference in the handling on my bikes with stock suspension via as little as 1/4 turn of rebound or compression. 1/8 turn on one of them. No exaggeration.
Consider talking to any suspension tech that does it for a living for riders who make their living riding. Or read Andrew Trevitt's, Sportbike Suspension Tuning, or Race Tech's book......
If the adjusters produce no results it is very probable that, as they say, the oils have turned into fish oil. The oils have lost their viscosity and need to be replaced. One of my bikes started doing that last fall so it got new oils this winter.
Always this order: sag, rebound then compression.
At least that is what I have learned and experienced.

what was the quoted rate for suspension setups? I may be doing the same...
I've seen this with bikes that were practically straight out of the showroom. It varies from one to the next. Sometimes one adjuster will have an effect and the other won't, on the same shock. Still, the outcome is the same as you have explained, though: if one of the adjusters has to be taken all the way to a limit and it's still not enough of whatever it is that you are adjusting, then the fork/shock needs to come apart for something to be changed internally. Often there's only so much that can be done using the external adjustments ...

Cornwell adjusted my suspension as courtesy at a track day. He then told me if I really wanted true suspension, I'd need about $2500 (basically full ohlins) . That's worth about as much as my bike, lol.

Depending on the bike, just using Racetech or Ohlins valves in the forks will make about the most difference and they're relatively inexpensive ($175+tax for RaceTech Gold valves for my Kayabas this spring). Some bikes will respond better to a shock (older ZX-7s/ZX-7Rs spring to mind). It also depends on the track you are running... on Calabogie, it's so smooth that you biggest bang for the buck is likely having the right springs... at Shannonville, TMP, Mosport, Trois Rivoires, you're going to want the best damping you can afford.
For street bikes, the same applies although damping is usually the issue with poor or worn-out suspension. I've had great luck with Penske stuff and the Elka products look good - and are Canadian-made.

On page 18 of Trevitt's book he mentions that some bikes are known for significantly degraded suspension performance in as little as 4,000 miles (6,400 kms). Replace the oils.
Top level racers apparently change it every few races! Must be nice to have a mechanic doing the routine work.

That's great, if you have a re-buildable shock. How many ordinary bikes have those...
They told me $65.
I do not know the answer to that but do know for example that the stock shock on GSXR's can be rebuilt or at least have the oil changed and the nitrogen recharged then. I had it done once by the local dealer. They told me they do many stock forks and shock oil changes for street and dirt bikes.

what do you get for $65?
is that just setting up the sag, or will that also include tuning the rebound and compression damping?
if it's for all that, i'm so gonna do it too... it'd be awesome if they did group rates but I doubt it.
I believe for all of it. I will double check when I make the appointment. I would be a bit of a rip if it was just sag, considering anyone can adjust that.

I can bet aint gonna be 50 bucks by the time they are done
Edit: $65 plus tax and they will set sag and (on that bike) turn the dial to the top on all other settings which to me is worse than anything else they can do
But hey, it ain't my money, I am just giving my opinion from doing it in the pass with a shop on my ZX6R and doing it myslef on my GSXR, any other bike in the past I never bothered doing anything to them

Each fork leg can be adjusted independently of each other,, this is how precise fine tuning is done.
They are joined by the axle, having one fork leg set differently than the other will not cause them to move at different rates from each other, nor will it cause any other issues.
The Newest Ohlins forks and cartridge units have the compression adjustment in one leg the rebound adjustment in the other.

A lot of the newer bikes are like that. I think the new R1 is set up that way IIRC. It seems counter-intuitive but if MotoGP is doing it...
