look at what i have been given

[merv]

A question for paulywombats or anyone who knows about the electrices of an st1100 .
any idea what  this bunch of wires are for they under the canopy by the back light. I have the wires for the back light and the indicators. This bunch seems to be spare if so could i remove them.

Not saying I'm right, but a friend had one and all that wiring was for police beacons etc. he was told.

Thanks Coppersmith
now you said that, that would make sense

Trying to get the swing arm of and out

[merv]

Got it

Now i got the swing arm out what do i do with it. In paulywombats thread he mentions that the swing arm has an offset can someone explain this and show me where the offset is and how i  would allow for this in creating a new swing arm. Any information on this would be much appreciated.

That's a hard one to explain basically the centre line of the bike is from the front yokes steering and the centre of the seat.   but you really need the bike on a bench setup to get it right.
The offset is the difference between swing arm mounting points and the centre of the bike it may only be an 1" or less

I'm guessing most shafties have this offset, my kawasaki did.

Hi Merv

Wiring is indeed spares, I have similar bunch. You should have no use for them. ( Police equipement )

I used the axle as it was, i.e standard width. I put the swing arm in place and set the axle, using the centre of the axle as a datum, to the centre of the bike.

This then will show you where you need to place your steel to meet the axle.

You will see that from the left hand side of the swing arm to the axle is different to the right hand side.( different angles, therefore different lengths ).

Hope this makes sense and is of some use. I have a workshop manual if you need any information from it.

Hi Paul
Thanks for telling me about the bunch of wires. can you tell me where the offset is. Also do you cut both arms of the swing arm and make good. Is this how the drive shaft come propshaft run outside the the original fitting of the swing arm.

Hi Terry
Did you get my pm ?

Hi Terry
Did you get my pm ?

Yes looking into it

Hi Merv
I haven't a clue what the offset dimension is. It's a bit irrelevent anyhow.

I can only point you to the pic in my post to give you some idea of what I ended up with. It's limited in what it shows.

A company in Wakefield has done conversions using large diameter tube which they have bent, so many ways to go.

really up to you now.

[minimutly]

You have a problem Merv. Ideally you should have set the bike up between a pair of parallel rails, taken measurements either side of each wheel, with a bob weight from the seat Rails down to confirm you've found the middle.
Now you have the bob weight only. But never mind, it'll be good enough, provided you can get a middle measurement from the front.
So a "jig" (wooden or steel) is required, unless someone can tell you what the offset is, and even then setting it up isn't going to be easy.
 How do I know this? BTDT.  well I didn't even have the seat rails, and regretted not pulling the engine and setting the frame in a jig before cutting, so that at least I had a level reading for the frame (by passing a rod between the swing arm bearings), but you live and learn.

Thanks for the replies  paulywombats and minimutly. I was just starting to think about doing a jig as you mention minimutly, i think that's the way to go, at least it would give me something to work from.
