zd90 mammuth chinese dirt bike parts

[Conquiztador]

Have purchased a s/h one of these cheap. It's a chinese small dirt bike. 90cc. Took apart and found that she needs new piston rings. Have not had any luck in trying to find a NZ agent. I can have rings made up, but easier if someone carry bits.

Any idea where I can find some?

They appear to be the same as most chinese bikes and be honda copied engines.......might be cheaper to repower? Somthing like this http://www.trademe.co.nz/Trade-Me-Motors/Motorbikes/Parts-accessories/Engine-drive-train/auction-169598108.htm

Nah, all there and motor is sweet apart from the rings. They are made of crappy material and have lost their tension. As said, I can have rings made up and won't be too expensive, but if there are rings somewhere then... Might even be that Hoinda 90 cc rings fit?
