Yes. You're on the bike, someone lifts the tail, measures sag. Then they press down on the tail & measure sag. Average the two numbers and that's what you subtract. The difference between those measurements is your stiction, and generally greater than 10mm means something needs to get looked at.

Very nice. I'll have to go back out and recheck it then. I know I need a new spring anyway because I don't weigh anything but at least I'll get some more accurate info by doing it the right way.

Yeah I need to get a new rear spring as well. I weigh the same. I'll keep an eye out on this thread and copy what you do once I see the procedure.

I'm your weight, changed my rear spring to 500lbs and is perfect.
Until you do that, back out all the preload from the back to get your sag.
Still, you'll be bouncing around going over bumps.

I think 40mm front is too soft, try 30-35mm.

All the springs I have seen are rated differently than that. Is there another measurement for the spring rate? Have you changed the springs in the front also?

Do it with a friend, with you in full riding gear including a back pack if you wear one.

Always measure from the same points on the frame swing arm to the small piece of tape you placed on the bike above the swing arm point.

It's more accurate to do it hot because of stiction when the suspension is cold. Dave Moss shows you how to do it on his website.

I changed both front and rear.
Front is .85kg/mm (stock is .9kg/mm)
Rear is 9kg/mm (500lbs)

Fork oil is 5w (stock is 10w), air gap 110mm.(Dave Moss said 100mm)
Depends who you ask, the stock front spring is good for our weight. I'd definitely change the stock air gap. Maybe I don't need a softer spring if the air gap is 110mm.

I've tried 550lbs spring, it felt a little harsh. Some people on the forum uses 450lbs. This is for someone weighting 135lbs.

As long as you in the ball park, its a matter of preference.
