While I'm waiting for the next trip to the garage, I've ordered some new tools. I want to use safety-wire on the rear sprocket and the caliperbolts, maybe other things too. I ordered drill guides for both nuts and bolts from Ebay. Tested it today, and it worked great. Didn't drill all the way...
Today I mounted the rest of the parts needed to take it for a real test run.
Choke; I'll find a better better place to mount it when the tank is on.

Made the seat a little more comfortable ;)...
Is it possible that these are original (or repro) rubber intake boots that have hardened and shrinked over time? Watch the video with sound :o

First test run on the road. Thank and seat is stowed away until all the wiring and cables are routed correctly. I'm quite happy with the seating position. Work done today is; 520 conversion, mounting brakes, throttle and clutch. Next time is carb tuning :) After that cable routing and...
New carburetor boots. Ordered the original Suzuki ones and the rubber seems brand new

I took apart the carbs and cleaned the float needle and filter. Now there's no leaks and the fuel level is correct when measured through the clear hose...
This is a picture of how my bike was assembled. Some kind of thick radiator hose sits loosely over the intake boot and carb opening.

Next picture shows my brothers bike (same model and year). This is an airtight assembly:

Thanks, I'll check it out. I didn't remove the floats when cleaning the carbs as I knew they worked before. Probably got some soda powder in there when cleaning.
I've also read page 4-5 and onwards in the workshop manual for an explanation on why gas flows from both holes, so I'm now confident I have it narrowed down to wrong float setting or some obstruction or similar problem connected to the needle not making a good enough seal to stop the gas from...
I'm learning a few things about carburettors today..
The hoses I thought were overflow-circuits are really just for venting. The reason for connecting hoses to them is so gas will flow away from the engine in case of a crash where the bike is left lying on the side. Makes more sense since...
Found a good rebuild tutorial online:

Stupid as I am, I didn't bring the carbs home with me...
Short lived happiness..
The two carburettors on the left side of the bike are leaking a lot and there was also a leak between the two on the right. The small leaks between the outermost carburettors was fixed by replacing the O-rings on the connecting tubes. I changed theese on both sides. Se...

Quick and temporary M-Unit hookup.
On the input side I've connected Key, Start/Kill (pushbutton) and Horn/Config (pushbutton, to initialize bluetooth pairing).
On the output side, I've connected Ignition (power to ignition and coils), Start...
I'll also throw in a cuple of picture of how the bike looks now. Putting the headlight, carburettors and airbox on really made it look a lot closer to beeing a rideable bike :) I've decided to powdercoat the rearsets black as I think they stand out too much from the rest of the bike.
Bike by...
In my mind there would be room for electronics under the seat, but when the airbox was in place, there wasn't even room for the seat :P

I've used the original seat "hinge" and turned it upside down like this

There is a downside to having the bike 1,5 hours drive away. Sometimes I plan something and impatiently order the parts, and when they arrive it doesn't quite turn out as I wanted.
I was planning to use mini switches like on the image below on both sides so I ordered a set of these:
But with...
Made a small "bending jig" as I wanted to try out some different ideas for the headlight mount. The first version had an extra loop for mounting the mini blinkers. I thought it looked too cluttered so I removed it.

Nice work :) Excited too see how the front wheel/brakes turn out. When you live in the north, you at least have a long winter to do your modifications ;)
