Hello I have just joined and thought that someone here will know the answer to a question i have

I have a Honda CBR600 ( PC19) engine in a Honda CB1, i wondered if the later F2 F3 pistons @65mm had the right deck height so they could be used in my engine, to firstly increase the compression, which although stated at 11:1 is NOT, it is closer to 10:1

and secondly, the extra +2mm will increase the cubic capacity to 640cc, and you know what the yanks say...... no replacement for displacement

if anyone knows the deck height ( centre of gudgeon/wrist pin) to the top of the top land, then please do tell me (for any of the 65mm piston engines )
