Losing 90mm

Some measurements made me realize that handlebar could be a bit more narrow.
Rigged up the complete handlebar in the wise and the measure begun.
25mm of each end plus the 20mm end plugs.
A total of 90mm(3,5") was the verdict.
The shortened handlebar in the wise

The lost witdh, 20+25+25+20 => 90mm(3,5")

Tech inspection one

A HUGE step on my path of building my bike have passed !
Tech inspection one went according to plan. Seems like I've made wise choice's and got help and info from experienced people along the way but off course because also a great dialog with the tech inspector. I had several of solutions I wanted to discuss and it went great, now I have enough good input to continue the build to the end. I will also keep in contact with the tech inspector if (when) I get in to issues along the way.
Maybe the biggest issue I had was the one with the turbos.
But we decided that I finish the bike first and does the final inspection with stock 1200 engine and next(?) year I will do a upgrade.
A much smaller procedure then the one I'm doing now.
And also there will most definitely be enough issues along the way even without the turbo/EFI install so I will do than nice and easy next winter.

But first up, deconstruction again...

Final mockup

Complete final mockup done and looking fiiiine. Everything worked great and all went according to plan with all the details I've made. Next step tech inspection one (of three) and then teardown again. After that I will paint the frame black and put everything back again. The big four steps remaining are seat, wiring, oil lines and brake lines. Then its just the endless small "last things" that remains.


So happy how it turned out.

Distance in the lathe

After i finally figured out the measurements I had to do some final machining on the sprocket spacer.
Both diameter and thickness got some treatment in my little trusty lathe. 


After a while the bench looked like had found a silver mine.

Primer

So the day came that i didn't believed existed, when the frame was "done".
I rigged it up, cleaned it and started to lay some primer on it.
Two thin layers. First I thought I could use this color the first year but I think I have to paint it in some darker color, black?
This is just a temporary paint I will use the first year(s) until I feel the bike is ready for real then it's time for its final paint, probably black powdercoat.
It's not even allowed to paint the frame before tech inspection one, but protective primer is OK.
Tech inspection one is just around the corner so I will probably pull it apart again after that to paint it.
Not so labor intensive but still some work.
I might regret it later if I go for just the light primer.

Rigged up, completely cleaned with acetone and ready for layer one. 

Primer done

Speedshop interruption


I had some delay in the Speedshop recently.
I went with some friends to the Motor Bike Expo in Verona, Italy.
Awesome happening both the city and the fair itself but mostly all the amazing people I met during the stay!
Inspiration for my own projects got itself a rise of course but the path for the projects for now are quite ready. But some planned details will be reworked.

Last minute adding

Just before the deconstruction I discovered that the voltage regulator had been forgotten.
So a simple bracket had to be made and welded in between the front legs.
Not at all a time consuming job at this point but if I had discovered it when the bike was done it would have been a slight drawback for sure.
First a bit of iron. 

Angle the ends and after that just drill two holes. 

Some quick work with the TIG and a suddenly I had a voltage regulator bracket.
