Timing chain cycle vs. sprocket marker position

Yes, it is by design ... because it helps to equalize wear across the sprocket teeth and chain links. Here's why I had originally shared a link in the comments which presents the formula to calculate what's known as hunting tooth frequency . Mesh rate aside, this is governed by the the number of teeth in the sprocket and chain, a and b respectively: gcd(a,b) / ( a * b ) // gcd = greatest common divisor But mathematically, this is just a fancy rehash of the lowest common multiple of a and b : So by choosing a and b such that the LCM is high, one can better distribute the wear across the sprocket teeth and chain links by allowing for more chain travel before a given sprocket tooth and chain link mesh together again. This becomes important if a tooth gets chipped or damaged, or if one of the links in the chain causes undue wear due to (for example) manufacturing variation. Here is a list of LCM's for your example: lcm(36,80) = 720 lcm(36,81) = 324 lcm(36,82) = 1476 lcm(36,83) = 2988 lcm(3
