suspension advice needed

recently brought a sv 650 race bike.came with a invoice for fork springs emulators and something else

taken apart and 2 codes on spring
270029 and 95
does the 95 mean 9.5 the weight

find these soft anyone know if i can go harder
plus what weight oil and what air gap
i weigh 13 .1/2 stone with kit on

any help would be grate cheers

I'm surprised you find these soft. I race on .95's and I'm near enough 20 stone in my leathers!.

Are you sure it's not down to compression damping? When you say soft, do you mean they dive on the brakes?

The spring weight is designed to give you the correct preload/sag. What are your sag settings?

You should be running 0.90 springs for your weight on the track and either 15 weight or 20 weight oil (cold and warm weather respectively)

At 13 1/2 stone I would go .9 or more, would think ,95 to be about "correct" actually.

I agree with the point about compression damping, you could also avoid bottoming with more oil.

where the hell did that come from. I'm sure I typed .90. Now edited.

according to the Racetec Spring calculator you can go with either .90 or.95 depending on how much you weigh out of your leathers.

cheers for that

yeh seem to dive alot and bottom out mate of mine is doing them

do you know about the air gap aswell cheers

Set the air gap around 110mm and see what the forks dive to under heavy braking. if you have less than 1cm of travel left on your nylon cable tie (arround the fork stanchion) you could add 15ml of fork oil = 10mm fork oil level. If they feel too stiff take out 15ml.
