View Full Version : Suspension fitting questions

Sorting out my suspension this weekend, have a low miles K2 GSXR 1000 rear shock and a s et of Hagon front springs to fit to my SV650S K3.
A couple of questions if I may;
Hagon have supplied 7.5 weight fork oil with the springs, would I be better off running 10 weight as I weight around 13 stone?
On the rear shock, any one have any tips for fitting - have swapped shocks before but I know I will need to cut the undertray to accomadate the GSXR shock?
Thanks all

7.5wt is definately too light. 12.5 or 15 would be far more suitable.
Cutting the battery box - make sure the tip over position sensor gets reloacated in a sensible position.

13 stone I'd say
I used 15w and I was 14 stone at the time :cry:

Ah, but im 15 stone and find std 10w fine for UK roads. I tried 12.5 and 15 and found both of them whey to hard.
What i would suggest is that Khewett try the 7.5 and if he dont get on, then move up a grade of oil, or at least as a starter, just drop the springs in the stock oil.
Ah, but im 15 stone..........
And the rest.
Only if you live on a diet of helium for a week and don your helium underwear.

Thanks all,
Really want to replace the oil while I'm at it so may go for the 10 as a start.
Didn't realise the tip over sensor needed moving for the rear shock, glad I asked!
Anyone got any pics of the top area around a GSXR shock fitted to a 650 K3??

Another Q, Hagon suggest a 120mm air gap with 7.5 oil.
If I use heavier oil should I change the air gap?
Also any views on the air gap, people here seem to have used 110mm in the past?

I'd've said that's too light... I weighed 11st when I replaced the front, and I was runnign Ohlins .80s (I think) and 15W oil. That was on the heavy side, if I'd kept it I would have gone to 12.5W I think. But 7.5W?
Of course, Hagon are suspension specialists and I'm a monkey with an internet account ;)

To be fair I trust the experience of you huys over Hagon :D
Anyone else have a view on airgap / oil?

Huh?
Ah :oops: :lol:

is there a tip over switch on the curvy sv's that needs relocating in the event of a nicve shock being fitted and the battery box cut?

I don't believe so. When I got knocked off last October, my bike was laying in the street for at least 30 seconds with the engine running.

I think there is a tip-over switch on the injected bikes, just that it's not much good. That could be wrong though.

Don't trust everything you read on the NET :wink: .
If I'm not mistaken the Hagon springs are Progressives and probably longer the the originals. Personally I would say go with the Hagon recommendation(follow what ever instruction come with the springs). Ring them and have a word if it puts your mind at rest.

You don't HAVE to move it if you're careful with the cutting. But if you do move it, you gotta make sure its placed in the correct orientation or the bike wont start.

No. Carbs require gravity to function, and they dont if you place them on their side, which will normaly kill the engine.

Would that affect the damping though? It may well effect the amount of preload spacer you want, and that would impact the airgap potentially (Hagon usually supply new spacers don't they?) but I'm missing why that would clal for thinner oil...

The length won't but they would have chosen the oil based on what what ever the spring rate/s they have worked out for a particular bike. I mentioned the length as Khewett was asking about that.
I was in the same situation with my hyperpro springs for my bros. I went as far as checking different the oil weight/air gap for about 3 or 4 different manufacturers .
If I recall correctly they all called for different weights and air gap. I tried the various weights and air gap Hyperpro with but eventually ended up using the recommendation as it seem to work the best.

All fitted this weekend, will post some pics:
Hagon progressive springs - are the same length as the orginal so you use the spacer went for 10 weight oil seems the right choice for my weight and a 120mm air gap.
GSXR rear shock - easy to fit just the cutting away of the front bottom of the battery box required, I moved the tip over sensor along towards the side of the bike a little and attached via gaffer tape it remains hidden away via the side panels.
I used a small piece of mdf to raise the rear floor of the battery box about 1cm and replaced the battery. Shock makes a huge diffrence will now just have to tinker with all the settings to tune it for me.
All in all easy and worth while doing the suspension and handling is vastly improved, one happy camper!

I just recently replaced my front shocks with hagon progressive springs for the sv and they came with 15w oil so i'm surprised that you got 7.5w with yours, I have a 2000sv but they're all about the same weight. Anyways mine seems to work v nice with the oil that they came with, just make sure you get the air gap right.
Anyone got pictures of cut battery box?

You won't have enough rebound damping with uprated springs and anything less than 15wt oil.
120 airgap will be fine

Sorry this thread's really old in case you hadn't noticed. Would have clicked watch this post so I could find it again, but can't find that option anymore.
So I have the only current question. But some good stuff in this thread .
