I'll be ordering a new chain and sprockets soon, I plan on using Ironman sprockets as i have heard so many good things about them, and cant afford to replace sprockets frequently. But im not sure about a chain, The one that came stock on my YZ was quite the turd, I had to adjust it at least every 2 rides, if not every ride, and yes it was lubed very well. I did do a search and didnt come up with what i was looking for. I was considering the renthal R1 works, I don't really want an O-ring chain. So, if anyone has anyone can recommend a long-lasting X ring paired with a set of Ironman's that would be great!
