Having read thru this thread and the ZX14 service bulletin I decided to check my bike today. I note that the torque on the adjusting collar stated in the bulletin is 15N-m. This is down from 25N-m in the FSM. I had the engine out of this bike 2 years ago and followed the FSM torque specs upon reassembly.
I marked the position of the head of the lower eng mount bolt before I removed the nut on the left side, ensuring that the bolt did not move. I marked it at the 6 o'clock position. I then followed the procedure detailed on page 7 of the ZX bulletin. The head of the bolt finished as shown below when torqued to the lower spec. Very interesting! The frame is now less stressed in the weld area.
Crappy photo but you get the idea.
The torqueing procedure requires the eng mount bolt to be turned to the left (undo). This screws the adjusting collar out of the engine case, forcing the eng to the left side because the head of the collar is now tight against the inside face of the frame on the right side. To state the obvious - turning the head of the eng bolt turns the adjusting collar as it's 'locked' into it.
I didn't check the upper adjusting collar as I have T-Rex bars fitted, plus that's not where the point of potential failure is.
I examined the suspect area thoroughly and found no sign of cracking before starting..
