Clearance between the outside surface of the brake disc and the right side of the calliper holder. On my 1982 CB750 it is calling for 0.7 mm or 0.028 in feeler gauge in the manual. I can't achieve. Once I tighten the axle in for it to shoulder on that spacer it can't be achieved. I have clearance but I don't have 0.7mm. Has anyone had a similar situation and what did you do?
