wow...never saw that before. Is it Made In China wires? Is it arching there? There is not much current to heat at that point so it is an odd failure.

I just rotated the cam 1 link. I believe there are 42 links between the marks when set up. I had to go to 41 to make up the change. The tensioner takes up the slack.

I moved a single chain link on the cam sprocket then chose the right offset of the 3. All you have to ensure is that the crank is at tdc then get the cam marks to align.

I took 2mm off an N47 on L28.
