Is the tensioner on straight? Are the ) and ( plates installed either side of the crank gear?

Just realised you posted this in two sections. Just post once.

Even though you are able to use a D Series engine with B Series cam gears, it looks to me like the offset at the attachment point is all wrong hence the belt doesn't sit right. Do you have them on the right way?

What happens when you manually rotate the assembly? Does the belt run true?

Here's some info that might help you. Please use this information carefully - it is at your own risk. Neither myself nor OzHonda can accept responsibility for this information and how it is used etc etc.

"You can use B-series cam gears on the DOHC ZC, however, the marks for aligning the camshafts on the B-series gears are not the same as on the ZC gears. The B-series gears have 16 teeth between the teeth with the marks, on both the top and bottom of the gear - the ZC gears have 15 teeth between the teeth with the marks on the top side of the gear and 17 teeth between the teeth with marks on the bottom side of the gear.

To use the B-series gears on the ZC, the mark on the left side of the gear for the intake cam is OK but the mark on the right side of the gear for the exhaust cam is one tooth off - you need to scribe a new mark on the next tooth above the tooth with the mark for the B-series and use that new mark for lining up the camshafts - here is where the new mark goes:
