Just have springs on the forks, is 10w to little? Should i go 20w?

If just doing springs, 20w is your best bet.

Springs are a little to hard on me, i only weigh 160 with full gear on, so if i used 10w would the suspension be more complaint?

 

[dubtecv2]

To some degree, yes - but only because it would be under-dampened. I'd get springs that are appropriate for your weight before skimping on oil.

Why exactly 20w, wouldn't it just make it stiffer?

What rate springs do you have?

 

[andyauger]

Judging from rider's reports on this site, you should stick to 15W if you are below the 185# range (with the correct springs). The damping could be a bit harsh with 20W at 165#.

Consider Traxxion emulators and damper rods. They are worth the money. Stock springs should be OK for street use if you're talking 160# in gear. If you're 160# "neat" then you probably could use a tad stiffer spring.

My last sv worked well with springs and 20 weight, and I was the same weight as you. Too light of an oil and the front end will feel too busy over rough pavement.

no. you will still have same spring in there. if to stiff for you change spring.
going to lighter oil than needed for spring and temperature will only make rebound worse.
