A little while ago I purchased an AIRSAL 70cc kit with 45mm Bore. Well one of my piston rings broke and I found out that they discontinued this kit, and I haven't been able to find a piston ring for this kit for a couple months, does anybody know where I could find a pair or does anybody have one or a pair they could sell. If so, please let me know, it would be greatly appreciated. I would even consider buying the whole kit again if I really had to. Thanks.
