First I checked out what was really damaged besides the obvious parts. Brake disks measured 3/100mm slag which seems allright. Front rim has 0.8mm, I will leave it like that unless I really feel it during riding. But it is not complete yet. Surprisingly frame is optically straight now, there was a minor bending that obviously vanished from the crash.
Basic problem was the bent forks. The pictures below show it before and after straightening. I stopped not before I was unsure which direction to bend to next. So forks are nearly perfectly straight, but cross section suffered a bit. One can make better wooden holders to avoid this. Here are forks before and after straightening:
For those who are interested. This is my proven non-commercial fork bender who did this job:
In case you want to try out this yourself, don't use a hydraulic jack. It won't work in horizontal orientation and if it does, it will contain a lot of air which can expand when something breaks under load. May gives a steel torpedo to hurt you seriously.
You also should be sure that the cellar walls of your home are solid enough. One of these five concrete bricks in the picture cracked and I do not think the CB650 fork is a very strong one.
Now except for the exhaust, everything is fixed and checked at least for riding again, although there is still much to improve. I guess I will do a test ride the next time but I still do not really feel like riding again. My healing progress is very good, but I am still unsure how to continue about motorcycles.
