How many links?

[ks-waterbug]

If I go up two teeth on the rear and my chain is 110 links right now. How many links should I add? This isn't for a Busa! Thanks everyone.

my stock was 17/40. I went up 4 teeth in the rear. stock chain was 113 links. had to buy a 118 link chain and cut 3 links to keep stock wheelbase. if this helps.
