The complete fork. I'll remove some of the screws for sandblasting and powdercoating later..

Borrowed the cnc-router again. This time for the top triple. Did some prototyping in oak for speed.

Ordered gear indicator and warning lights from ebay. The gear indicator was awesome, but the warning lights was a big disapointment
For some reason they were all blue. Waiting for another shipment with the usual blue, green, red and orange. I will alsp cut down to four lights and have one common light for the indicators. The reason for the hole next to the gear-indicator is that I forgot to alter the settings before testing on the oak. The aluminum I've bought is 8mm thicker and i trilled 6mm down into my friends router table

The reason for the uneven outer edges is that I went too fast and broke the end mill piece. Had to use a band saw to finish it off. It's only for testing so it doesn't really matter, and I have more end mills at home.

I was struggling to find a good placement for the speed sensor. I've seen some people mount them in the rear brake, or under the front fender, but I will try to modify the original speedo-gear unit. That way I won't have to machine a spacer to replace it. I will drill a hole inside the original hole to place the pickup perpendicular to the magnet. Then I'll grind off some off the original gear so the magnet will sit flush.

I sodablasted the carburettors and dusted them of afterwards with compressed air. I thought I was careful not to get any soda inside them, but my father said I should open and clean them anyway.

Glad I did, because he was right. Also, although I've adjusted the needles in my zx7r and knew there were diafragms in there, I didn't know the big oval channel in the inlet was directly connected. I imagine if you blow hard enough directly in there, you might rupture the diafragms. Mine where fine, but I will clean my carburettors some other way the next time.

Sometimes the build finds its own path and I have to tag along to see where the build goes. I've been good at spending time on planning to minimise the need for doovers. But when I thought I found a similar exhaust on the internet as I had stowed away 3 years ago, I was dead wrong. Measurements was wrong and after countless tries to make the new exhaust look good on the bike, I gave up. I then decided to make my own. The goal was to have the same amount of stainless perforated tube as in the Kercher.

Lucky me had some stainless perforated tube laying around.

Took some half inch aluminum to the lathe and made the end piece. It is stepped with the same thickness as in the perforated tubing. Did also put in some set screws to secure it.

Packed it:

And hammered it gently in. All that is missing is a screw on the backside to keep it from moving.

Thanx
I've had a go at designing the wiring for the bike. I would be very grateful if someone would look it over and correct mistakes
I'm not sure if I should connect the regulator to battery or switced plus, so it would be helpful with a hint about that too.
