The stock spring is much lighter than the replacement I put on my 08
Stock spring rate is 5.5
I'd have thought that would be ok for a 165lbs rider
I'm 210lbs and run a 6.0 with 25/98mm sag
Have you measured you sag figures?
Don't get hung up on spring rates - its the sag figures that ulitmatley determine if you need a softer or harder spring, not the published rate

Checking the race-sag and free-sag is the best way to verify that the spring rate is correct for your weight.
The WR's have never been equipped with Ti springs from the factory.
There is really no reason to repring your WR unless you need the bragging rights that come with a Ti spring.

OEM workshop manual I've got states rear srping rate is 5.5kg/mm for 08 model - not sure where 2grimjim is seeing 5.4kg/mm
The 5.4 spec comes from Yamahas parts fiche.
Workshop manuals are often printed in advance of the bike being produced and changes made prior to the bike being produced may not be incorporated in the manual.
Race Techs spring rate search states that the OEM spring rate is based on their testing and not manufacturer data.
