Kinroad XT125 Sprocket

Hi all, I have a bit of a problem I'm hoping someone can help me with.
I have a Honda XL250 fitted with a Kinroad XT 125 GY engine and I'm having problems matching sprockets.
The problem is that the front sprocket on the Kinroad engine is 428, but the rear sprocket on the XL250 is 520. Can someone please tell me which 520 sprocket which will fit the Kinroad?
I've tried to find a 428 rear sprocket for the XL250 but had no luck so far.

Any help on the matter would be greatly appreciated.

Cheers

The front is using (428) JTF259

Thanks for the link Humanbeing. I will give these guys a try.
From looking at the drawings and specs of the Kinroad and Honda sprockets, it looks like the original Honda part may fit the Kinroad.
