Hi guys and girls!

I am looking for a new piston & barrel kit for my 1981 Honda CB650 Custom. The barrel is actually okay, a piston kit is more important. I am from South Africa, does anyone know where I can order a piston kit? I tried Wiseco, no luck. Thanks!

If you speak to the guys at Arias pistons in California, they will be able to help you. I sent them one of my pistons' a few years to give them something to copy, so they can hook you up with some Pistons for around $650 American. I had them make me a set for a 61 mm bore, but they may be able to change the bore so whatever you need now that they have the important measurements. Good luck

Thank you so much Chief78! I actually ended up cleaning the original pistons quite well, and have ordered a set of original standard rings from David Silver spares. Just have to source some new piston pins now!
