This is my problem, even when the cam is loose and movable by hand, even at the edge of the cam the closest I can get is .5 from one belt and 2mm from the other.
The only way I can get it closer would be to tighten the BB tensioner, which would lower the top belt. But in order to get the top belt low enough for clearance to be in spec, the tension would be more than double the tension spec
