How do i know what chain to get, in the manual it says 520 o-ring, but on all the site i look for them it says 520x100, 520x 114, 520x98 etc. how do i know what it is, i have a polaris sport 400L. and whats with the DID and RK on the sites after the 520x whatever?

 

the second number is how many pins the chain is..you need 76 or 78 pins i think..

 

Spring for a good chain and get an X-ring from DID or a Z-ring by Regina. I've got a Z-ring on my 250R and it runs smoother with less resistence and is supposed to last longer.

 

i was wondering if you knew how to put on the chain? if you have any info on how or where it would be greatly appreachiated. thank you jack
