Have you tried jacking the bike up from under the engine so it extends the forks more, does it say anything in the instructions about cutting you spacers down?

the bike is jacked up, but i havent seen anything about cutting the spacers, illl have another look though.

ANy other thoughts, apart from put loadsa pressure on it :D ?

thanks

When I did my springs with the bike jacked up the top of the spring was just below the stanchion and I had a 1in spacer, I just put the cap ontop of the spacer and pushed down but be careful not to cross thread the cap!!!!

No other thoughts :lol: but it should not be that hard to put the top back in. Even if you do manage to put the cap back on you would more tahn like like have too much initial preload.

How much of the spring have you got sticking out of the stanchion? Have you go adjustable caps?

Cheers

no adjustable caps, and there is about 6cm maybe more of the spacer sticking out of the forks.

i was thinking the preload would be too much...but i know nothing...

anyone think there should have been a spacer with the kit? and it wasnt included?

Andy

p.s. my bike now wont start after faffing about with the back putting a zxr shock on, the main fuse blew, so i put the other one in, and it still wont start, so i try to ake it out and blow that one...

when i say wont start, nothing comes on at all....any thoughts here :D

thanks!

Some spring kits come with spacers some require you to use the origonals cut down! Did you disturb any wiring when you installed the shock it might be shorting out some where!!!!

6cm(60mm) is definitly to much. No need to even think about spacers at this point.
A few maybe silly questions for you :) . With the way it is we will be looking at cutting the springs themselves down :shock: :wink:

You sure you have the right kit?

How have you raised the front?

you will have been given replacement spacers! or you will have to cut down the origonal ones! the origonal spacers and aftermarket springs do not go together!!!!!!!

spacers will have to be round 25mm long! then put spring in then put top cap on!

does help if you hang bike from the garage roof or something else.....dont have the bikes weight on the froks!!

hope this helps!

Hyperpro dont come with spacers they are all meant to be drop in kits, You have the wrong springs :!: :!: :!:

right the hyper pro springs i have are from jhs racing, they are for the k3 onwards and i have a curvy however as he gave them to me he said its fine as they are the same for both models....so they should fit correct?

Iam lifting the bike up by abba stand and a jack under the engine.

I have disturbed wiring, but i cant see anything different to how it was...all seems the same, sooo i dont know why it aint working.

Ill put the fuses in in the morning when i get them and see, hopefully itll fire uyp...but when has my life been that simple!?

thanks again

No, he's talking ******** - spacers in the pointy are far shorter than for the curvey. Well, that is unless you're not supposed to use any spacers are all that is.

have you tried matching the length of the original springs and spacers against the new ones?

Just as a matter of interest, did you workout your static sag, to enable you to set the right spacer length?

And I seem to remember the the three new SV's we done didn't have the same length springs as the couple of curvys, unless of course you're not supposed to be using any spacers and the springs are progressive? but does sound a little odd :shock:

Just a thought.

Cheers Mark.

hmm, the progressive springs and my sacers are longer than origional springs and spacers...

interesting that curvy spacers are longer than k3 on...however ill have to wait till tuesday to see him now as its the useful bankholiday...great for everyone except me...wo needs to see jhs...

i havent worked out the static sag, from what i can gather the kit should automatically do the static sag to i think it was 2cm.

without the springs in there is a good 3cm gap between the washer on the top of the spring and the fork tube top...so i cant see not using the spacer as an option...

at the moment old springs are in there with the new oil...but i would like to use my £97 worth of springs and oil together...

i think it looks like wait till tuesday and complain bitterly...

unless anyone knows different!?!?

thanks

looks like you've answered your own question there.

i havent worked out the static sag, from what i can gather the kit should automatically do the static sag to i think it was 2cm.

although it's possible to make a general improvement over standard, as sag is worked out by the riders weight, unless the kit is weight specific, then that's going to be less than ideal.

Cheers Mark.

Aah...my mistake :oops: You wrote

no adjustable caps, and there is about 6cm maybe more of the spacer sticking out of the forks.
!

and I read it as 6cm sticking out without the spacers. Sorry for that.

My Hyperpro springs for my Bros was a drop in as Rob said. I think it's fair to say your problem is that the springs were originally for the pointy.
That does not mean it might not :?: work as all you need to do is cut the spacer down.

Having said that , if I have paid for a kit that is supposed to be a drop in personally I'll send it back and request the correct kit.

Cheers
Ben

ps: With progressive Kits , IMHO it is best to start of with the recommendations of the Kit Manufacturers. My static Sag for my Bros was supposed to be roughly about 23mm and it was spot on.

They are progressive springs so the sag is not as important as with linear due to the constant changing rate, between 20 and 30mm is ok

Firstly Hi all first message but long time user and SV owner (2002).

I am in exactly the same position as you. Bought new Hyperpro spring kit from JHS. Queried that 03 kit was sent for 01/02 model but James (JHS) told me this
is the kit JHS recommend.

Anyway got round to changing springs today and a bit worried when new spring was 130mm longer than old one. E-mailed James and he mailed back within 20 minutes saying that you have to cut down the spacer.

I was also adding pre-load adjusters so cut the spacer down by 130mm for spring and 18mm for adjusters. That left me a spacer length of just 50mm (so about 68mm if not fitting adjusters) but on reassembly the resistance on the fork cap was about the same. Bit of a fiddle cutting then filing the spacer down to correct size but do-able.

Have only managed one leg today so will do other tommorow before I can test ride to see if all is well.

Hope this helps

if not then e-mail James at jhs.racing@lineone.net

Hmm... Did JHS explain why they recommended that(kit requiring cutting spacers).

I think I may be right in saying Rob has fitted a few Hyperpro kits and appears to be saying something different(consistent with my experience with Hyperpro).

Did JHS mention that the spacers would have to be cut prior to you emailing?

If It were me I will be emailing Hyperpro to find out exactly what the situation is. Threy are usually very quick with answering emails. Telephone calls are also not a problem if you can't speak Dutch :lol:

Spec wise the springs for curvy and pointy are pretty much the same and as they are designed to be used with std spacers the length varies from model to model.

Cutting the spacers is not a problem, I didn't know you had K3> springs, Hypeerpro's UK distributer changed last year (no longer exe-tc)and I don't know who has taken them on, but they may be an issue with supply.

For the sake of cutting the spacers as opposed to a possible couple of weeks wait there won't be a problem in how they perform

What did James say then?

Interested to know if I did the correct thing cutting the spacers down!

Hacked off at the minute anyway as after refitting my newly sprung forks I now have an oil leak on one fork. Don't know if I disturbed something whilst changing the springs and oil or just bad timing.
Anyway don't fancy trying to fit new oil seals myself so off to Suzuki next week with an £80 bill. Whoo Hoo...
