Think i'm slightly wrong here Gaz, if you've got a 115 conrod in your engine already you should already be using a 115 piston.

Think you may need to strip it if you haven't got any receipts of what was fitted.

The only way you'll know the answer is to measure the distance between the centre of the gudgeon pin hole on the piston and the top of the piston, if it's around 30mm then your crank will have a 115 or 116 rod, if it's around 39mm then you'll have a std 107 rod.
