getting the front sag right

I've just checked my front suspension sag measurement using the "zip tie on the fork leg" method ( I have no friends) and with the preload adjuster wound right in the best I can get is a without rider sag measurement of 20mm and a rider sag measurement of 40mm.
my actual measurements were
full extension = 150mm
bike only = 130mm
rider = 110 mm

If my understanding is correct I'm just under on the WOR sag and on the upper limit for RS.

Do I need to reduce my spacer length or replace my springs. ?

currently using stock springs, I ride on and offroad and wiegh 100kg (220lb) (give or take:mrgreen kitted ready to ride.

Yes, you need new fork springs appropriate to your weight. Sonic also makes excellent straight rate fork springs:

Actually, I think everyone has to upgrade their fork springs. I don't know if anyone has ever seen the 90 pound ballerina who apparently does the suspension testing for Suzuki. She's got to be getting close to retirement after 3-40 years of crappy stock suspension.

I changed my fork springs and havent been happy. I still think I need to add a little oil. Anyways, how many clicks are avaliable on the forks. The stock settings were at 5 and i'm at 6 now. Just curious. Maybe I need to go a few more.

ok 0.90 sonics are fitted, static Sag is 27mm, Dymanic is 41mm

I think (from memory) sag for Strom should be

Static 25 - 30mm

Dynamic 35 - 45mm

am I on the right track here

(I ride on and off road )
