Jack up kit fitted. Can YOU spot the difference?

[know your limitations]

Ordered a 25mm jack up kit and just finished fitting it.
Wasn't sure if it was wise to do it after work as I could have buggered it up and left myself without wheels for the morning.
Anyway, all went well with no dramas and I quite enjoyed doing it. Even cleaned and re-greased bolts, bushes and bearings.
Old dog bones centre of hole to centre of hole were 144mm. New ones c2c were 140mm.
Just sitting on the bike, suspension feels a touch firmer (good) but not ridden it yet.


If I'm honest, I'm a little underwhelmed as I can't see any real difference to the profile of the bike and my feet seem to touch the ground to the same degree as before, so can you guys spot the difference?


Before and after shots below (not necessarily in the right order). Didn't replicate camera angle very well though, sorry.

I take it the top one is the after shot?

I take it the top one is the after shot?

Because it actually looks higher or are you going by how many tools are left lying around?

i was going by the wheel on the first looks like it is lower..... the bike wont be higher while on the stand affter all.

4mm dont seem a lot, thought my jack ups were more than that c2c but honestly dont remember now.
but it didnt make a HUGE diff on mine, it was noticable sitting on the bike and to some degree while riding but looks while parked up made no noticeable diff.

it was worth doing for the price but wasnt a be all and end all mod

I thought the first shot looks minimally higher, trying to judge by both pics of the bike and the wall behind......

Chain slighly looser?

you wont see any difference with the bike on the centre stand will you, you plonker :lol :lol :lol :lol  exept maybe a smaller gap between the rear tyre and the floor :lol :lol :lol

Is your washing machine the "all weather" pattern? :lol

2 important things to remember about dogbone lengths
a) the overall leverage effect they have is far greater than their overall length, hence 'rising rate'
b) changing the leverage ratio will also change the suspension operating curve, in your case the suspension will appear firmer.

Thanks for all the replies. It was the first pic that was the "after" shot, so well done SOME of you.
I suppose there were a few other visual clues, (fading light, cleaner dog bones, as mentioned etc.)

you wont see any difference with the bike on the centre stand will you, you plonker :lol :lol :lol :lol  exept maybe a smaller gap between the rear tyre and the floor :lol :lol :lol

Exactly, or to put it another way, a larger gap between the wheel and the tail piece. So you would see a difference even on the centre stand  :rolleyes

Aah, you fell for the red herring. I was only just starting so only had the socket set out.


I've since had a good couple of rides on it and because I've also dropped the forks, this is turning into a seriously enjoyable Fazer for minimal outlay, £18 so far.
It is MUCH sharper to ride but totally predictable and the rear suspension now copes admirably with my substantial frame.
Thanks for all the help and pointers in this and other threads where I've asked questions.


This is a very simple job to do, made even easier with two pairs of hands and I will gladly offer assistance (for no cost at all) to anyone who fancies giving it a go but is a little wary.


A HIGHLY recommended tweak!
