Chain and Sprocket for 04

Adding two "teeth" to the rear is what they meant....or you could drop one tooth on the front....it would gear it down slightly lower than adding two to the rear. Dropping one in the front, is approx. like adding ~2.7 teeth in the rear for our setup. I dropped one tooth in the front on my bike, and I added a speedo healer (about 110 bucks) to correct the speedo error. Stock speedo is off ~5-7 anyways, and this knocked if off a good amount more so. Now it is on dead nuts. You also have to figure, that if you regear it lower, and do not correct the speedo error, then your mileage will be prematurely high.

Any major brands work. Some swear by RK, some by D.I.D, some Renthal, some EK, etc, etc. I mostly use RK or DID myself. X-Ring is the most expensive type of chain (preferred by some over O-ring), but opinions differ. I had an O-ring, and now an X-ring. Basically, an X-ring is supposed to seal contaminents/water out better, this then holds the lube in better/longer thereby extending the life of your chain.

Many folks (myself included) prefer to permanently "press-fit" the rivets to link the chain, as opposed to using a masterlink clip which many feel is inadequate. Keep in mind that you will need a chain breaker/press-fit kit for breaking the chain, and press-fitting the rivets on the new one. You need to know what you are doing before doing this though, including measuring the amount diameter of the press-fit rivet until it meets a predetermined spec.....or you can just bring it to a bike shop and they will do it all for probably 50-100 bucks.

Not sure where you are located, but Sprocket Center has some good deals.
