Above, a picture of the 3D printed parts I made. The axes are those of the signal lights. I made also 3D printed parts as the new parts for the signal lights mounting (could see them on the picture)

Oh crap
I use imagesia, which asks me everytime if I want to keep the pictures for later, I say no, I'll change that
But, about the last pic, I can see it, and you?

ok, thanks. I presume that they are still visible, for few days or weeks. I'll try to find another solution

Ok, the two lower cases are cleaned. I decided to not paint them. They are in very good state and full cleaned. I do not like painting mechanical parts because I already had some bad experience with that. I thought about peening them also, but I want to keep smg like a brand new - old - bike. So, no threatment on these parts. I ordered the last oil seals, so re-assembling will start by this end of week.
I want everything assembled on the bike before end of april, for the first start around the same time.
I will work on the fairing, assembling the bubble after having polished it today or tomorrow.

Yesterday evening, because I'm still waiting for my oil seals, I made a first assembling of the engine on the frame and tried to fit the 600 gsxr exhaust. I already knew that it would fit with some minor modifications.
- remove the center stand --> ok. On the exhaust there is a threaded hole just at few mm of the center stand mounting plat, so I'll be able to use it with a adaptating laser cutted plate.
- bend / cut and weld the tubes in front of the head. There is not the same angle at the exhaust interface on the head, so There will be some work to do here, moreover to make the exhaust fit just under the frame.
- modify the big tube at the muffler interface because it hits the frame. I also have to move the muffler about few 20 / 30 mm closer to the frame...
And i think that's all. Why to fit a 600 gsxr exhaust? Because the ID of the tubes is 33mm (much bigger than the original all gs exhausts) and the tubes are already made in stainless steel.
Fist I wanted to cut the exhaust under the frame, and let it without muffler or anything. But I think I'll get such a screamer that a muffler will be compulsory to keep my ears in a good state....

hi guys
I'm planning to order a chain kit. It will be the gs 550 / 650 top end with carbs / velocity stacks and gsxr exhaust. Do you think that I have to order a 15 / 50 set, or a gs 650 15 x 45 set? thanks!

Hi all!
Some news, I assembled the two lower cases last night.... I think the engine (without the head) will be in the frame next saturday...
For some reasons, I bought some gasket sheet (to cut my own oil planar gaskets). I made a new gasket for the oil pan, and starting by a web picture, I laser cutted a new one... Here this is a first test with a paper sheet.

Hey Boris I am really enjoying the thread. I found it awesome that you were 3-d printing parts. I plan to 3-d print a new dash for my bike. I found all the information interesting, but a lot of it I didn't understand because I have never done any thing like this before.

thanks ace 
I just started to play with the markforged two, today (nylon / kevlar, nylon / fiberglass, nylon / carbon fiber)... Getting a LOT of ideas now!

Hello again!
Not o lot of people interested in my project....
BUT
I was happy to get back my gs 650 head yesterday, aluminium welded. I just have to make again the second combustion chamber and put new valve seats..... still, still, still a lot of work and I want it finished for the next summer!
Could someone give me some advices about degreeing the 550 camshafts? What is the best setting?
thanks a lot!

hello all!
I got the head back and almost ready to be used, this week. I measured the combustion chamber volumes, with the gasket surface milled some 0.1 / 0.2mm.... just for start.
Unfortunately, I measured, with a 1.25mm thickness head gasket a ratio of... 8.95:1!!! Which is not so big. I'm a bit disappointed, I think this is because the valves are a bit "back" in the head. So I have few questions:
- which maximum value is possible, with your experience, for milling the head to increase the CR?
- Moreover, I think that, even if I mill the gasket surface, The squish band will be the same which is.... the value of the gasket thickness? I think 1.25mm is a "too big value" and could be reduced...
- I would like to get a ratio of 10:1, so I measured that I would have to remove maybe 1mm height of the head.... I think this is a lot, but maybe not, your experience would help me to choose.
I'll make a first assembling to measure the distance between the valves and the pistons this week-end and the squish band clearance. I think this would help me to choose...
any feedback possible here????

Ok,
Still waiting to see if I can increase the CR without having any chance to damage the valves and the pistons..
I think I will be able to start it before end of may....

I just looked through your whole thread, pretty amazing stuff dude!
How did you fix your CR issues? did you measure the valve>piston clearance and then milled the 1mm off?
Im doing something similair to a GS450, see my thread
Good luck!

Thanks dude.
About CR stuffs, I milled first 0.4mm because of a full combustion chamber rebuild (welding...), then I did 1 first try just to measure the distances and then I removed 0.6mm. The limit for me was the intake valve / piston clearance (1.25mm).
