But you didn't hit? Hope you gave him what for.

i would have if he had stopped, just drove off

short of replacing the swingarm...

i will be adding locknuts just put these on to keep it together

Just curious as to how strong the swingarm is, will it take a bolt through it then tightened up

See, if you'd had the standard crap caliper, there's no way you'd have braked so hard.....

true, but then id be buying a new nosecone and many others parts

Correct me if I'm wrong but you've fitted a 1000 rear caliper to an FZS using the 600 hanger did you modify the hanger to accept the caliper?

The other likely culprit is not undoing the torque arm bolts when adjusting the chain, over time not undoing them twists the mounting and eventually they shear off, just like yours has! Seen it quite a few times over the years on all types of bikes.

the hanger was modified with filing a bit off.

the arms always unbolted when i adjust the chain.

The area where you would be drilling to take those bolts is probably the most highly stressed part of the swinging arm, so I would not be too keen on doing it. However if you do drill it I would at least put a backing plate under the nuts to spread the load to the sides and prevent crushing the top face of the swinging arm.
An alternative way would be to make up top and bottom square shaped plates that span the width of the arm with two bolts on each side. Not pretty but it would avoid drilling the arm and spread the load.

Forgot to add, every credit for managing to stay on board and also avoiding impact

I would think the damage was done long before you bought the bike, once it started a hairline crack, it was only a matter of time.

Over tightening the bolts does not help either.

A problem in many bikes with the underslung caliper, but not a common problem.

This has been covered in a previous thread.

It probably corroded away looking at the state of your bike

Haha thats what living in the countryside does unfortunately, its surface dirt from not being washed in 4 days, underneath is shiny

except the torque arm.

Anywho, got it all apart today, drilled swingarm and fitted the bracket, the swingarm is actually quite thick at the top and bottom, using 2x m6 bolts bolted it all up.

I will be adding locknuts but these where chucked on quickly to get me to the fixings shop.

doesnt look pretty but works.

The arm will be coming off soon to be striped and re-painted, been due for a while!

Ignoring the grime I think it actually looks quite neat.
From an engineering point of view I would still prefer a backing plate at the top, particularly as there is no spacer inside. I don't recognise the bolts but if they are the type normally used for wood I would change them for proper bolts of 8.8 grade.

Those bolts look to me like furniture bolts - the type that go through your bed end legs and screw into a lug bolt in the bed section and have a hex head
Im wondering if the 4 holes in the swing arm would be an MOT issue

Paulfzs · « **Reply #14 on:** 18 December 2015, 04:54:37 pm »

i asked for some strong steel bolts and told the fixings place what it was for and this is what i was given, Im going to fit a plate to the top.

As mot stands, going to call up mot guy and see what he says, worst case ill cover it up for the mot or say its standard

first sign of any stress on the swingarm ill be purchasing another and replacing it, i had 2 do 2 emergency stops today .. hid projectors apparently arent bright enough! and no signs of wear or stress yet.

was the back axle torqued up correct, i had a tyre fitted once and the axle bolt was not torqued up to what it should be and the same thing happened.

Paulfzs · « **Reply #16 on:** 19 December 2015, 12:28:34 pm »

This was definitely more a case of corrosion

Bondyboy96 · « **Reply #17 on:** 19 December 2015, 03:32:14 pm »

I have a swingarm for sale!! Either with our without wheel and rest of back end

Paulfzs · « **Reply #18 on:** 19 December 2015, 06:09:41 pm »

im honestly not looking forward to having to change the swingarm lol

unfazed · « **Reply #19 on:** 19 December 2015, 06:47:10 pm »

Are you serious, changing the swinging arm is easy

About 10 bolts in total to undo,

Once the wheel, hugger/chain guard and brake hose clamp are off, it is only 2 bolts.

Axel 1
Chain/hugger 3
Swinging arm protector 1
Front bolt of torque arm 1
Brake hose bracket/s bolts 2
Linkage 1
Swinging arm pivot 1

ooh, i thought itd be a bitch to do!

how long if it all goes to plan?

greenman · « **Reply #21 on:** 20 December 2015, 01:17:10 am »

I stripped mine out, changed shock, greased linkage bearings and put back together in an hour and a half including making a cup of tea.
