Can anyone suggest chains and sprockets and bark busters they like?

Chain. My personal favorite is DID. My top 3 are DID, EK, and RK Racing. I have never had an issue with any of those brands.

The real question is, do you want a standard chain or O ring style? I have a DID VX2 chain on my Hawk, almost 3k miles later and it's still good as new. Regular cleaning every 500-800 miles. Chain wax or dry lube for an O ring chain is all I use. They cost about twice as much, but also last about 2-3 as long in my experience.

If you want just a standard chain. DID 428H 128 Link will work well. usually around 30-35 dollars. The other brands and their similar equivlents are all within that same price range. Search through Amazon.

One tip I often give people is to buy a chain break and then shop chains on Amazon. You will notice that different link counts sell for different prices. My DID VX2 520 chain in the link count I actually need is $80, but I found the 120 link length selling for $52 from the same seller. Why? Less popular link count, so lower demand and thus lower price. All I had to do was break away 18 links.

Sprockets. I stick with JT, and not just on my Hawk. I have had great results with their sprockets on every chain driven bike I have owned. They are kind of the industry standard in quality sprockets.
