My friend just got an 84 200x. It needs to be bored and a new piston. The only problem I have I do not know the piston size. It is a Honda piston the numbers on the top of it are 965 and on the side it is NL 446 1. Does anybody know what size this piston is. I would measure it but I do not have the right tools and if i use a tape measure I could be off.

Thanks

 

Check the wiseco or LA sleeve website, they may have a cross reference number.

if you are going to bore it have the shop tell you
