I'm swapping out the stock suspension on my 03 RX-1 and putting in a mono-shock from an 06 Apex. I've seen a lot of comments about re-valving the shock but is it really necessary? What is the purpose of the dial adjuster?
 
Monoshock stock springs are soft, tend to bottom out easily if you're over 200 lbs. or ride hard. Most add either a heavy duty rear spring and or revalve the shock to match. The RA dial adjuster stiffens the shock. There are 20 clicks on the dial from soft to hard, and it does make a difference of what setting you have it on.
 
If you revalve you willl find yourself not needing to adjust the RA dial not nearly as much as stock. The biggest reason I had my 05 mono revalved was to not break more front suspension arms. It helped alot ! Of course this was some time ago and the arms have been really beefed up since then and every year the shock calibration has gotten better.

I'm assuming that you are talking about revalving front shocks to avoid breaking suspension arms? As far as the rear shock, does the factory set them up for the heaviest riders and people revalve to reflect their actual weight?
 
Valves not set for the heaviest riders. To save money, you may want to just try moving the spring circlip on the cam adjust end of the shock to stiffen the spring. You need to compress the spring to move the circlip, there are three positions. The present postion is the softest and the third is the stiffest. I think the second position might be best, then you have the 7 cam positions as well. Then adjust RA to match. Of course you need to ride it and adjust to suit your needs.
 
No I meant to not break the "w" arm(allthough its not a w) on the front of the rear skid. My front shocks are stock valving.

To get best ride possible you will need the correct spring(or springs) for your weight and a quality revalve. If I remeber correctly anything over 200lbs rider weight and the stock spring should be replaced, of course that depends on how you ride too. Pioneer did mine way back in 05 and it was a HUGE improvment over stock 05 setup. Alot of guys like Hygear and I dont think you could go wrong either way.

Ive ridden the older yamaha suspensions(pro action) and even in stock form the MONO is a major difference in comfort, plus its got great transfer.
