Piston rings for a cheap Chinese Pocket Bike

[have_faith]

Hey guys, i have a question for anyone that can help.

Got given a cheap Chinese pocket bike a while ago and since then ive pulled it all down to fix the few problems that it has had, hole in expansion chamber wrecked rear sprocket etc. and ive come to my final problem, piston rings, took piston out to find that the piston rings were all cracked and broken, so now i have the question of where can i get new piston rings from, Any help appreciated
cheers

Johnson Engineering, who used to be behind Carlaw Stadium, then moved (about 20 years) to the Gt South Road, can supply piston rings for almost anything. but they moved again recently and I've forgotten where. And I think they changed their name too. I'll try to find out

Now owned by Franklin Engineering Services *** 129 Manukau Rd Pukekohe 2120 PH :: 09 2384079 ... apparently. They claim to be able to supply from 25mm bore upward.
