Fork weight only impacts rebound and won't compensate for incorrect fork springs. If you have the stock springs then I would consider focusing on correcting that as they are for 140lb rider I believe.

However, you asked and many use 7.5 to 10 weight. You can also use less air gap, but that really only effects bottoming resistance And not much else. I forget the actual amount of oil in each fork (190ml maybe?), but someone here will know and chime in I'm sure.

Well I've put 5 weight in them... I've had always used that weight on my 450 . Different forks of course. Hmm.... It felt stuff as in good before they busted . Not squishy... Just pretty right. So stiffness comes from the thickness of the oil then is that what your saying on these forks because I noticed there was no adjusters

There are compression adjustment screws on the bottom of the forks. Did you do the shim stack mod when they were apart?

Oil wt will effect rebound
+1 on the shim stack mod
And definitely order the correct springs for your weight if you not planning on doing a fork conversion
