You will need to rebore to 73.5mm to achieve a 1380.
Other things worth considering to maximise the gains from the extra CCs are:
Camshaft and timing gear
Basically, with more CCs, your engine will want to suck in more air (a HIF44 would be sufficient I'd think) and blow out more exhaust. The cylinder head could be modified to allow this, as would the exhaust. The Ignition system would ensure it burnt the fuel properly and the camshaft would keep everything doing what it needs to do, at exactly the right time.
The clutch may need upgrading to cope with the extra power! :wink:
