Godday Casey,
the tube runs through  frame, then by mid-swing, down in front of rear wheel

Odin and Dirk, many thanks gentleman, I can now continue and finish getting the engine and the frame back as one unit.
I have deliberately not taken a single photograph of the bike while it's being rebuilt but rest assured I will be posting one or two when she's done.
Thank you again guys.

The bike has been converted to a single exhaust some time ago.
Before rebuildingn the bike I took the entire exhaustt apart, cleaned it up, cut it in half and removed the rattling rusted bits of baffle and welded it up again, then replaced the balance pipe and then had it all chromed.
It looks fantastic and with the extra compression that having two completely rebuilt cyclinders complete with intact and working head gaskets I just know she is going to sound awesome.
So Odin no extra expense, except the rebuilding of the old exhaust and the chroming of the entire system.NZ$800.00 to do the chroming.$15,00 - 2,000 to make a new twin system out of stainless steel.
Being a poor unemployed person I took the cheaper option, I actually like the single pipe and the exhaust note it generates.

Hey there guys, well the engine is fully in the hole now, bolted up and ready to go.
Got the rear pipe sorted out.Looks great all shiny new Chrome amongst all the black engine and frame components.
Many thanks Odin and Dirk for the pics and the advice , so far.
Now I've another couple of small problems.
The first one.
The right side exhaust bracket bolts to the pillion peg,I know this, what I don't know is on the inside or the outside of the side plate/frame.Of course it can only go one or two ways but so far which ever way I put it on the bracket it does not seem to then want to marry up with the actual exhaust pipe.
Also on the same side there is an engine mounting bolt that goes through the side plate and into a caged nut on the inside of the main stand frame.
It appears that there is something else between the side plate and the head of the bolt, but Ai don't know what.If i put the bolt in and wind it home the thread goes right through and wont tighten up.
Your help and assistance is eagerly awaited.
Still not taken a single picture of this restoration.

Nearly forgot to add, I've got a jo0b again, bit of a come down from previous employment but a job is a job.Been going for a week already.

Gidday there Odin, well I've obviously not explained myself quite well enough.
I am all good with the exhaust system.What I need to know  is simply which side of the right hand side Triangular aluminum side plate(it carries the front foot rest and the exhaust mounting bracket) the exhaust bracket bolts too.

As I wrote in my earlier post this is also a small problem for me, perhaps I also need to explain it a bit better.

Again looking forward to hearing from you.
Thanks for the good wishes and congratulations on the job, it's actually going very well and I'm enjoying it.
Just had an idea.
The picture (such detail was amazing) that Dirk posted for me last time is brilliant, all I need is for that picture to have been taken  including the aluminium side plate and showing the rear and front footrests and the exhaust bracket position(IE; behind the side plate, in front of the side plate)
That would do it. Cheers again.
Caseye.
