I’ve run into conflicting info I’ve read a few places it was 84links and a few it was 86links. Here’s my info
Model Year: 1991
Make: POLARIS
Model: TRAIL BOSS W918527
But when I search for a chain and sprocket it gives me an 86L. I have a rear sprocket with 34 teeth. Some I’ve found say they have 38 teeth regardless of the number of teeth they are 86L(all have 13T front). I’m pretty confused at this point lol any help or info as to why a different link and different rear tooth would be greatly appreciated.

Sorry I don’t get this. So it a rear 34T either way with a 86L chain?

Exactly - 36 link chain, 34T rear sprocket 13T front sprocket

The original sprocket was part number 3222050 - it is substituted with 3222068 - still 34 teeth, but might be a different color - if you order 3222050 you will get 3222068

The chain is 86 links if you go down one tooth on the front sprocket it will still use an 86 link chain, but if you go up 3 teeth on the rear sprocket you would then have to go to an 88 link chain

Simple geometry
