As supplied the pipe nipped in towards the back of the bike instead of being parallel.

I made a new stud up from stainless rod with a spacer to line it up better. The stud goes all the way across the frame and also holds the kick stand on.

Another spacer and a longer bolt sorted that out.

(the other fitting on the bolt is the rear crash bar)

More SS spacers sorted that by lifting the front mountings.

The original stud was a cycle thread and I'm trying to move towards metric where I can.
As the stud had to be longer anyway I cut the head off a suitable cycle bolt and cut a metric thread on the end to make a cycle/metric stud.

Finished off with dome head nuts (I like dome heads)

Again, finished off with domed nuts loctited on.
This was before I'd thought of the mixed thread stud idea I used on the seat so it's not metric.

(you don't need shouldered nuts if you get the washers right.

I didn't like the bottom brackets on the crash bars so I drilled the engine plates and bolted the U bolts straight on.
I lot tidier.

The nut and bolt second from bottom is just to fill in that spare hole (what was it for?)

I didn't like it stuck out at the front.

I could do with a better looking horn sometime.

(Someone has since told me the horn won't like the heat and vibration - if it busts I'll just have to get a nicer horn :-)
