6 speed, 86 link primary chain, anyone got a measurement?

[Hybredhog]

       I'm assembling a '08 FLT primary with a new 32t solid motor sprocket & a M6 adjuster. I had one apart last winter with the same set up (32t/ M6), and everything fit fine, but this bike is loose as F**k. I don't have a 86 tooth chain around to compare it to, so does someone got a free length measurement, and or are these that prone to stretching? its got about 70k and had a relatively easy life other than BIG riders.
