Just got my suspension back from a complete revalve and spring change.  I was told the bike was sprung way to heavy for me and needed a lighter spring in the back.  I got the shock back.  Installed it, and my sag is only 74mm.  Should I ride it a bit first then re-set it?  the retaining collars don't have alot of room to go too much looser!

maybe you just have the wrong size, the correct sag should be measured before the bike on the stand.

Ck all measurements very carefully, be very sure of what you have and then call the tuner. Sounds like he installed the wrong spring. I would not ride the bike until you speak with the tuner.

Easy to select the correct springs using my Static / Rider sag method.  You can't just have someone who has never worked with you or not helped set your sags correctly, pick your springs.  Too many think they send suspension off and when it comes back it will be adjusted just for them.  That is not how it works.  They revalve the bike to get the valving in the range you need it.  They may recommend springs but I have found that rarely correct.  You must adjust your preload on the springs yourself to get the correct rider sag and then you need to recheck to make sure your static sag is in the correct range. If it isn't then you have the wrong springs.  You then have to adjust your valving till you are bottoming softly and then go back in one or two clicks.  They can't adjust it for you .

Stock shock spring rate should be around 5.5. At 165lbs you should be at a 5.35 rate with 105-110 mm sag. Your bike is probably stink buggn and handling like crap.

He tested my stock spring. Said it tested between 5.6 and 5.7.  He intended to put on a 5.5 but put on a 6.0 by mistake.  5.4 is on order.  hopefully be here tomorrow.  If not I'll race with my stock spring this weekend.  BOOOOOO
