Or you can ship one to me and we can test at same timeAWWWWW FRACK NUGGETS...
I installed and properly maintained an RK 520 Non o-ring Chain for 30 hours of hard desert use on the WR500.
Reference Here
Now it's kinking something terrible. I pulled it off and soaked it and worked it... to no avail.
I am actually afraid to use this chain much longer.
So I'm going to buy another name brand non o-ring and a nice o-ring chain from the same company.
Run the non oring first, measure the life.
Then run the oring chain, measure it's life.
Compare.
