from ur pictures..a guess is that u never change ur coolant until it become so brown n also maybe never clean or flush ur radiator and got clogged and never cool down ur top block properly until the piston over heat n melted.....you can ask ah chong from plane for an honest quote perhaps.....you may need to change to a new or second hand top block if cannot rebore to fit new bigger sized pistons......new pistons and piston rings set....at least two sets of intake valve and exhaust valve...a connecting rod assembly to ur piston as it looks melted....,,,,..a lot of work and at least 2k maybe?

You can try Clifford from K&T, he's done all the work on my CBR400RR this year. I think he's a pretty stand up guy. Contact is +65-9669-6118. Don't think he's the cheapest but he knows his stuff, especially old Honda motorcycles.
