Steering damper

Years ago I bought a used Öhlins steering damper and initial thought was to put it on the Shovelbagger. But it had quite weird dimensions so it continued it's life hanging on the wall in the speedshop.
So the other day I tried it on Cosmic Dreamer and this time I had a match.
But to avoid flimsy screw-on brackets I made a real weld on bracket instead.

The steering damper before it found a new home on the Cosmic Dreamer. 

First cut bit of my old trusty friend Mr square tubing. 

Then add a bit of extra metal on the inside to make enough thread. 

Positioning and testfit with a hose clamp.

And tacked in to place ready for final weld when I take the bike completely apart soon.

Top engine mount

Time to finally fabricate a top engine mount.
I want a quite long mount to spread the stress over a longer area.

First a cardboard template. 


Then trace the template to 5mm - 3/16" steel and some rough cutting.


And YES I'm environment friendly and use as much as I can of the cutting discs. *Hehe*

I also made a weld on a spacer to get it in the center of the frame, then I drilled the mounting holes



Testfit on the bike and now some tackwelds and next time the engine comes out I can make the final weld to the frame.

More spacing

When alignment with the complete wheel was tested there was not enough spacing between tire and chain.
No biggie, just flip the front sprocket and about 0.2953"/7,5mm more is available, just use a thicker spacer between hub and sprocket.
To measure up the alignment I used a long square tube.

Spacing

So the weekend came again and then it was business as usual in the speedshop.
One of the things I fiddled with this weekend was to get the rear wheel spacing just right.
Not so easy as it sounds. Not just the spacers for the hub will have attention but also the sprocket and brakedisc spacing.
My friend Viking Cycles had a spare rear hub I could use to ease up the work.
And he also arrived when it was time to measure up the alignment of the sprocket.
With a long ruler and many hard words to each other we finally came to a verdict.
*Hehe*
Also the brakedisc spacing issue was later solved.
Now some final spacers for the sprocket and a touch with the lathe on the brake side spacer will do the trick.
My dog Kurt supervised today's work in the speedshop as usual.


Project thoughts

Mind wonder when projects develops.....
I have quite a good pace in the speedshop but with all my plans there will take way to much time to get it on the road.
Thought's about getting it road ready first and do upgrades winters to come instead.
So first it will be without turbo and with the trusty CV carb and the plan is to just get a registration and get some miles before the project continues.
Just to get a registration is a huge journey anyway with at least two technical inspections first.
One soon, early 2016?  where the main construction, welds, solutions, materials eg. are checked on a non functional bike.
And then when the bike is ready with all fuel, electrics, seat... yes everything, then it´s time for final inspection.
When that's OK there there is just the registration inspection left and after that you have a vehicle you built yourself.

Wheelies

Finally I had some build time of so I could do some wheelie training.
Naah, just needed a better angle to do some more spotwelds on the kickstand mount.
How it went....? Not my best welding accomplishments in the speedshop to be honest, but it was worth a try anyway.
