I was planning on doing both chris, if the engine is rebuilt and in the frame, i don't want to have to rip it back out and start dismantling and welding.
If you have reduced compression and retained stock 500cc capacity, I would say more oil and a cooler are all you will need. But if you have increased capacity and fitted a different piston, get the feeling you will be having other problems not directly linked to motor running overly hot.
