From what I can tell the stuff I am ordering will work on my 2002 gs500 but I just want to make sure.

Can somebody confirm that the following items will work?

Front sprocket: JTF516-15

Rear sprocket: JTR823-39

Chain: MOOSE RACING® 520 HPO O-RING CHAIN - 110 link

Yes if you're replacing oem 16T front with a 15T.

I actually like th 15t better than 16t in both city and highway riding. passing is very easy without shifting and it is less than 2mpg worse on highway. I get 3mpg better in the city with the 15t too. plus my top speed went up.

awesome that is good to hear, I am looking forward to the increased acceleration.
