For the sprocket question, See THIS POST from the has anyone droped 1 to 2 teeth on the front sprocket? thread.

Also see the More sprocket questions thread.

I found these and several others by searching for "rear sprocket specialists".

Jet kits for the 1989 to 2000 model years won't help you at all.  The newer carbs have an additional (mid-main) jet, and the pilot and main jets are different from the older style too.
