For your gear swap, you will have to change all three items. Presently, you should have:
8640517....17 tooth, red drive gear, and a
25513042..35 tooth, orange driven gear, with 16" tires or a
25513043..36 tooth, white driven gear, with 17" tires and a
25007338..sensor.

You will need:
8642620....15 tooth, grey drive gear and a
25513049..42 tooth, green driven gear, with 16" tires or a
25513050..43 tooth, purple driven gear, with 17" tires and a
25007339..sensor.

That's all there is to it. Good luck, and...

RACE ON!!!
