Well when I had the 41/15 which is standard for the 78K, it was 88 links. When you shorten a chain, you actually have to remove 2 links. My advice would be to stick with the 88 link and if it needs shortening, get a chain breaker. You might find the drop of 2 teeth on the rear sprocket will not make much of a difference for chain length.
The ride IS the adventure. The destination is just to get gas!
