Ok let's think about this for bit. This appears that there is an issue with the rear system. The first thing I want to know is if the Honda brake fluid was used in the bleed process. I would want to make sure DOT 3 brake fluid was used as if it had the Dot 5 synthetic it will swell the seals of the pistons in the rear caliper and the plunger seals in the master cylinder which will cause the pads not to retract and brake pad drag will occur. to fix this a complete rebuild and flush will be needed. If the fluid was DOT 3 fluid then maybe the rear pistons need to be pulled out to be cleanned. A lot of crud will cause the pads to retract slowly and drag. Since this appears soon after the recall process was done I would focus on the fluid used. Also the fluid may have been open for time and may have attracted moisture which may have contaminated the fluid.
Something interested happened yesterday.
In the morning while bleeding the system mechanic used DOT 4 Motul brand brake fluid. After the process I tested the ride but the problem was still there.
I was lack of hope and left the bike at the shop and come to work.
After work I went back to dealer.
The mechanic changed the rear master cylinder and installed the cylinder which was changed at the recall.
This time he used Honda brand brake fluid which is also DOT 4 and I took the bike.
So far the problem did not occur.
But I dont want to talk early. Sometimes after a while wobble comes back.
Yesterday after I took the bike rode approximately 20 km in the city and parked at home. This morning I came to work 15 km.
Finger crossed ıt dıd not wobble.
Maybe the problem was the master cylinder itself.
It was changed under warranty but maybe after the change the bad brake pads I used made to much heat and the master cylinder was broken.
I hope so it is and I never face this problem.
As I said I crossed fingers and continue testing the bike.
