1975 BMW R90S Restoration
Timing chain
Overall everything looked pretty good. The chain was WNL but loose and needed to be changed. We also discovered the plug wires from the coils were not "crossed" to each cylinder. Both wires from each coil went to the same cylinder. Easy fix.
Going into an unknown engine the first time is kind of scary. So far so good.

Great winter project
Make sure you don't put any part upside down and that all the bolts are tight
Good luck with your new bike

Tommy ..... thanks for looking in. Restoring that R60/2 is what started all of this. Im addicted but its a lot of fun and I learn sooooo much in the process. I need a new hobby when I retire in 3 years. I think found it.
I promise I will check every bolt and direction on this build.

Im addicted
This is my 5th bike
Not a BMW but it was my Dads and found it after 22 years storage
I thought I might be bored after retirement but now find I seem to create more and more projects
Wish I could posts more on this bike but this site is for BMW's

I would paint, and not
paint
I understand/respect your point about keeping it "correct" but its not going to be a show bike. Its going to be a rider. I painted the frame on my first total restoration (Honda CL350) and it looked great but its just not as durable as powder coating.
Can the average person really tell the difference looking at a restored bike if its frame is painted or powder coated?
The average person isnt going

That was great !!
I understand. There is a ton of crap to consider but I have to be open to "all" suggestions. Unfortunately the color scheme (Dayton Orange) and having the frame powder coated decisions have already been made.
When I posted my R60/2 rebuild I can't tell you have valuable the input was in determining what-when-where every nut and bolt went. Im looking for the same input here and Im open to any suggestion no matter how big or small. I could not do one of these restorations without the help from this group and others so I am very grateful.
Now my brain is hurting just thinking about all I have to do ......
1975 BMW R90S Restoration
My intention is to take the bike apart, go through it as much as I can then restore it. This is going to be a rider not a show bike so I want it to perform as well as look original. The plan is to change it from Silver/Grey to Daytona Orange.
So, this blog is to document what I do to the bike step by step. Im open for suggestions as well as criticism on anything/everything Im doing. Some will say leave it alone and ride it. I understand but if Im going to ride this bike I want to know everything is up to date and safe. If Im going to take it completely apart why not powder coat the frame, take care of some of the rust and make it look like it was brand new.
The bike came with a detailed maintanance book. Most of the services and modifications were documented. To confirm the last service I went through the bike and discovered all of the fluids and filters were new and/or fresh. That made me very happy. Now its time to get to work looking at the rest.
Let the journey begin.
