See this thread where gsJack answered a similar question for you:
http://gstwins.com/gsboard/index.php?topic=40584.msg455903#msg455903 (http://gstwins.com/gsboard/index.php?topic=40584.msg455903#msg455903)

The link gsJack gave at the bottom of that thread is to a chain calculator from Tsubaki:

For reference, gsJack explains how to use the calculator in this thread:

Basically, you need 4 pieces of info to use the calculator:

• Front teeth: 15
• Rear teeth: 44
• Chain pitch: 0.625" (i.e. length of a link = 5/8" for any "5" series chain: 510, 520, etc.)
• Centre distance: 25.5" (approx. value - use this as starting point because stock is 25.679")

RESULT
Your required chain length is 112 pitches.
Your ideal centre distance is 25.619 inches.
