400EX Chain Size?

[Wood_15]

I was wondering what size chain i need for a 400 ex with a +2" swingarm? I plan on getting a 520 o ring chain, but i need the correct sizing. Thanks a bunch

i am running a 100 link chain on my +1.25 inch swingarm. i have the adjustment as tight as it will go though. also, i am running a rear sprocket 2 teeth smaller than stock. i have a feeling if i go down to 99 links and i put on the stock rear sprocket that is 2 teeth larger, the chain won't adjust loose enough for me.
