my chain is worn out what kind should i replace it with??
any favorable brands? whats the link number? 22o's have O-ring chains right?

220s do have O-ring chains. mine is 108 links but it depends on your sprockets. Hopefully you have a big family with enough fingers and toes to help you count. You can buy any brand, Renthals seem to work well but are pricey.

i have stock sprockets and thanks lol

The sad news is , you should replace both sprockets when you replace the chain. Worn out sprockets will ruin a new chain.

+1 on the sprocket comment

oh dang....well thats startin to sound kinda expensive

Sometimes you can get away with not changing the sprockets, at least the rear

Just changed mine out today

Front sprocket had some wear and the teeth were hooked. Rear sprocket had barely any noticeable wear. I put the new one up against it and they looked the same. Teeth were not worn and the valleys matched up

So now I have a spare if I ever need it

Also be aware that some are saying the cheaper countershaft sprockets are loose and cause faster wear on the CS shaft. There was a thread or two on this causing the shaft to have to be replaced. I recently got a Renthal to replace a cheapie I bought. I'll have to take a look and see if my CS shaft is worn.

Well I only run cheap 12 tooth JT's on mine

I'll let you know how it turns out in a few years

I don't think it's just the chepies that are loose. Can't remember the brand but I had 24$ CSS that was loose on the shaft. As I remember the JT's I had were not loose.

Use Rethnal.... perfect every time. Best fitting css I have ever used... so I keep on using them.

Renthal ROCKS !

I can buy 2 JT's for the price of one Rethnal

So... It's not like they are expensive.

Make sure you use a narrow width o-ring chain - some are too wide for the kdx setup and can gouge things up. There is a lot of width variance in what's available.
