Folks,
Hopefully an easy one for you. I'm checking my drive chain slack, using a vertical ruler roughly midpoint between front sprocket and rear sprocket. I'm measuring the deflection of the lower run. Bike is on the center stand, in neutral.
In measuring the deflection, do I:
A. Pull the lower chain run down as far as I can, then push it up as far as I can. The difference in measures on the ruler is deflection.
B. Push it up from its resting position, measure deflection.
The 2 procedures produce quite a different result, about 2" for method A, 1.25" for method B.
Thanks.
