FORK OIL/SPRINGS

[H-Gerickemark]

hello,


After a bit of advice, has anyone changed there fork springs and oil on there bike?

What sort difference does it make?
does it cost a lot?
Is it worth doing on a new bike?


Any advice would be greatly appreciated.

Yes

Lots
No
Yes

Depending on what springs you go for you're looking at spending about £70 to £90. It's worth doing on the SV, even a new one, as the stock springs are too soft. It'll handle bumps better, but the main thing you'll notice is the front won't dive as much under braking.

Hey Squirrel,

Which Ohlins springs did you use. The Ohlins site lists no springs for a K3-K4-K5 ? As for the GSX-R shock, what type did it come from. I can get an SRAD shock or a K1-K3 shock.

[Flamin_Squirrel]

I got the springs from here: https://www.harris-performance.com/

GSXR shock was from a GSX-R1000 K1, which I found on ebay (paid £40 inc postage).

I think any GSXR K1 onwards will fit, SRADs as I understand it, will not.

Mmm. The one I can get is from a GSX-R 600/750 K1-K3

What oil did you put in the forks ? I was thinking 15wt

[Flamin_Squirrel]

I think that will fit, but I'm not 100%.

I've got 12.5wt oil, although I'm not that heavy (10-11stn) so that might actualy be a bit much. I can't be sure of this though... no easy way of experimenting. 10wt would probably be more suitable, or 12.5wt if you're a bit heavier.

Someone with more experience on this matter might correct me on this, but if you go with 12.5 you can't go too far wrong.

A total matter of opinion. I find the front end on the Sv just fine as std thanks.

Im 15st with leathers on and i got my springs from Maxston .9kg with 15wt oil I also changed the rear shock to GSXR1000 K3 all in all costed £150 and it has tranformed the ride. What you have to bear in mind is the SV is a budget bike and Suzuki can can save alot money by putting budget part on especial suspension. So it will make a huge diiference

thanks for the quick replys, think this needs further investigation! :D

i've been out practicing stoppies on my k4 , would i be right in saying that changing the oil in the fork would make no difference since it would still compress the fork all the way?

I'll shutup now :D

Just got the bike (2000 S) back from Riverside, Northampton who uprated the front fork springs with an Ohlins kit and I`m really pleased - improved the dive under braking and rides over potholes etc. much better and does seem to feel more `planted`.

Going to a heavier fork oil will increase the damping, so you will notice the difference in the rate of fork compression and rebound. Of course, heavier springs to go with it will make sense...then you pretty much have to look at the rear shock too, to balance things front and back.
Most guys over this side of the pond seem to favour 20 wt or even as high as 30 wt oil for track and racing.
Oh, and I'm a newbie on your forum here....I guess I ought to intro myself in another post.
Cheers !

So did I, that doesn't mean it can't be made better though.

Quick question to all the guys who have upgraded their forks - are you just uprating the spring and adding new oil or have you added pre load adjusters & shim kits as well?

Is the spring upgrade enough or is it best to do the whole lot?

[timwilky]

I got preload adjusters for my upgrade, without them it is impossible to set up the sag properly

[Flamin_Squirrel]

When we did the fork change day, several people needed to have extra spacers cut to increase the preload more than the adjusters would allow.

Since we just cut the spacers to the correct length o give the right preload for each person, being able to adjust it isnt really necessary.
