dogbone removel - kerb - 10-02-12
hi all
i just got my first fazer tho 2003 model
so my first question is the previous owner was a bit shorter than me
and he had fitted shorter dog bones
i have the orignal dogbones and want to fit them
do i remove old ones and refit orignal ones
the thing that confuses me is that theres only about 5 mm diff in dogbones
cheers
Re: dogbone removel - kerb - 10-02-12
oh and is it just a matter of removing the nuts at side of suspesion linkage
and then remove bolts and then remove dogdone
and then fit orignal dog dones and refit bolts and nuts
Re: dogbone removel - devilsyam - 10-02-12
shorter bones means taller not lower?

Hi and welcome
It's a bit more complicated but not much. Make sure you've got the bike steady and secure. When you undo the dogbones, the rear wheel will drop unless supported.
It would be a good idea to give the whole suspension linkage system a good clean, inspection and re-grease while you're at it.

To add what Mike and Luke said. I use a shallow wooden wedge and pop that under the tyre. It's a good easy way to get everything lined up when refitting the dog bones. you can do this by moving the wegde backwards and forwards. It also takes the wieght of the wheel when you take the bolts out.
When spannering on the suspension linkage tie the bike down or stick large heavy bricks in front of the wheels (I use two bits of railway track) to stop the bike rolling of the centre stand. If it fell on you it would hurt... a lot.

The wedge is a good tip, I use a door wedge from a hardware shop. Think it cost me 50 p but is plastic. A wood one would be better.
Also remember to torque the bolts on rebuild.
Pats site is a big help here but I am on phone so can't link it.
As said shorter bones increase hight. So don't panic when you take old ones off and they are actually longer LOL. 5mm gives a much bigger adjustment at seat hight than at dog bone level. But that said it isn't a HUGE diff. At least I didn't think so when I went from std to shorter bones....... Raised the back. But the I also have the front dropped 10 mm
Re: dogbone removel - devilsyam - 11-02-12
suppose i should say why not do the whole lot with new stainless bones all polished and a shiny r6 shock to sort ya rear end out :lol
this way you get instructions on how to fit the bones :rollin :rolleyes

Hi and welcome.
I would highly reccomend fitting shorter than standard dogbones (jack-up kit) as available on ebay for about £15 if you're not overly short of leg. This puts more weight on the front and makes the bike a lot more responsive through corners, dropping the front forks through the yokes by 10mm is also another easy mod that has similar results.
When fitting your new bones I beleive it is best to re-assemble everything with the bike on the centre-stand but to do the final tightening of the linkage bolts on the side stand as this helps eliminate some of the play in the linkage that is common on GEN1 Fazers.

Something I found a while ago, measurements are right for the standard ones as I measured mine while off.
It's not exactlty linear, and a few thousandths error shouldn't hurt.
There's that much slop in the bolts size to hole size already.
it doesn't require much precision.
Here's some figures based on several postings of measurements
made to raise and lower FZ1's.
The centre to centre distance between the bolt holes and the resulting
change in height.
137mm = 22.5mm
138mm = 17.4mm
139mm = 12.6mm
140mm = 8.1mm
141mm = 3.8mm
142mm = -0.2mm
143mm = -3.9mm
144mm = -7.3mm
145mm = -10.5
146mm = -13.5
147mm = -16.1
148mm = -18.5
149mm = -20.6
150mm = -22.5
151mm = -24.1
152mm = -25.4

Very good job and ihfos ....
Re: dogbone removel - t140 - 14-02-12
remember and adjust the chain when finished changing the dog bones
Re: dogbone removel - greatfun - 15-02-12
And also remember to get another standard side stand as the one fitted to the lowered bike will have been shortened!!
