Jack-up kit dimensions.

[Wideboy]

anyone got experience with them? lengths?

also anyone used with a kwak shock, i hear they can foul the swingarm if you jack the back up?

thinking of making my own but not sure on what lengths to jack up by??

[maviczap]

I've got some longer dog bones in the garage Gav if you want them. I didn't notice much difference when I had them fitted

[Wideboy]

how much do they rise by?

[maviczap]

Dunno, i'll go and measure them, if I can find them

[Wideboy]

ok tar

[Specialone]

Get a bigger bike ;)

did like the ST but they are no longer cool for some reason

You bi*ch, i used to like you.

Right I have one set of dog bones which are 105mm

Another set from a spare swingarm which are 95mm (cheap nasty ones, which I've never used)

Standard DB's are 100mm

[Wideboy]

i thought standard were 105?

[maviczap]

Mine is 100mm measured.

I'll check with the vernier caliper tomorrow

[Wideboy]

no worries mate, i was thinking jacking up about 2"

You will probaqbly find the dog bones are shorter to jack the bike up. If the standard ones are 105mm and the aftermarket ones are 100mm this would lift the back of the bike about 35-40mm, anymore than 40mm and you will have steering that is probably too quick it will be more unstable at higher speeds and the underside of the top run of chain may start to rub the chain guide away on the swingarm and then at worse eat away at the swingarm also.

I wouldnt go anymore than the 5mm shorter. For what you gain (not alot) its not really worth doing it in the first place. If you do change them through make sure there is no weight at all on the back wheel and swingarm linkages it will be ok if there was as you remove the long dog bone bolts but when you come to put the bolts back in after swapping the dogbones you need to push the bolts through with no resistance (the holes must line up perfectly) otherwise you are at risk of damaging the very fragile needle roller bearings in the shock mounting block, if you push the bolt through and a few little metal bars fall out the other side then you have to strip the whole linkage off and go to a Suzuki dealer to buy new roller bearings, then you will need to have them pressed into place. Is it worth the hassle or risk....? Not in my opinion!

You can go a lot further than 40mm at tail without losing stability. Mine is about an inch higher at the shock and an inch shorter at front.
No problems I have found. Personally I think jack up kits are wrong approach and you should use a longer shock, you don't know effect on linkage geometry and bad rear linkage can cause all sorts of stability issues!

Matt there are bushings in between the bearings and bolts. You pushing it through a metal sleeve, use a hammer if you want, that cannot harm the bearings.

[Matts-Yokes]

Ok thanks for the info, i was going off my experience of doing the same on a bandit 1200 years ago. Its best to be careful anyway but that would make it alot easier with the bushings to protect the bearings :p

chris, is yours jacked up with plates or a longer shock?

[maviczap]

I know he's got a fancy Penske shock which is adjustable for length

Mucho moola though

[Wideboy]

Ah i see

rich i'll pm you later

Made some plates, jacked the back end up about 2" but i cant really tell any difference, seems to go round corners faster with less lean (might be placebo on my part) but its not more agile

edit : pics no worky, cant link properly but they're in my profile
