Bouncy ride - would new springs help?

[bat-kam]

That's good. I will make the buy and report once new springs will be in.

How much oil did you put in in each leg?

Oil capacity depends on the year and model. Somewhere just over a pint per side.
I've been using synthetic multi-viscosity motor oil in all my forks for over 20 years. It works great, is very slippery, extremely durable and resists fade with hard use. Also cheaper than motorcycle fork specific oil.
What viscosity depends on how you want the damping. More viscous will give more damping. Stock for my '00 is 10w. Don't know if the newer models are the same. Probably.

Are those the right ones?

0.9kg/mm = 0.917N/mm

For oil level you don't measure volume, measure oil height with leg fully compressed without spring fitted.

Stock is 110 or so, usually I like a bit less oil, gap of 120mm or so. Personal preference to an extent and millimeter precision is not going to cause you to die in a fireball here!

I pour in the recommended volume, then check the height.
Suspension guys sometimes recommend adding more oil, for instance where you like the damping action, but are having bottoming problems, or less, if you like the damping action but aren't using all the travel.
Well, I see you ARE a suspension guy Chris...

Springs and oil bought. Once received I will give it a go in changing them on my own. Will I be able to do it without proper work bench and vice?

Yes just think ahead before you plow in

Crack the caps off before undoing bottom yoke bolts.

This video will give you the rough idea link
How are you going to support the front end?

[bat-kam]

Thanks, that is very nice video.

I haven't think of the way of supporting the bike yet. I have the front and rear paddock stands but the front will be in no use as the forks would be resting on it.
Any home grown ideas?

There are a few methods. Headstock stand is a good investment as is an abba stand. You could sell your paddock stands...


Otherwise, Ratchet straps over a strong roof timber and under the top yoke works ok when a rear paddock stand is also used. Some have used a car jack under the engine but I can't testify to the effectivness of that one.

I now have a front headstock stand but before I had it I opted for the ratchet strap method with a jack just to help steady

Folded Black and Decker work mate and a bit of wood under the engine also works well but you'll need two people. One to lift rear, one to shove wood under.
