Ring End Gap for 70cc

[shoom]

Just wondering if anyone can assist with what the ring end gap should be for a cast iron 70cc kit in a Minarelli Horizontal? (aerox)
The gap given for the original 39mm bore is .015 to .035mm , but how would this vary for the 47mm bore of a 70 kit?

Thankyou and Merry Xmas (hope you all get more scooters stuff!)

There is a ring gap calculator on the drop down menu on the left. www.49ccscoot.com/calculators.html

Please note when using the calculator, enter cylinder diameter in mm however it provides ring gap in inches. So a 47mm cylinder would have a ring gap of .008" or .2mm
