18/38 yikes what were you grass dragging???? Stock is 23/38 and I am not sure of the chain maybe a 72pitch?

count the pins 72 link would never work on 18/38

I think 72 is stock with the 23/38. He has to be using a 68 or a 66 pitch with that top gear.

70t chain is stock... if you run a 22/38 or less need to go to a 68t chain...
