XR200 or XL185 Engine Wanted

Hey guys, Snagged myself another little project for over the winter, it's an old xr200 trail bike. Plan is to turn it into a bit of a fun scrambler type thing, only problem is I'm currently without an engine for it - I've only got a little 125 that it came with!

So if anyone has an old xr200 or xl185 engine sitting around doing not much - let me know how much you are after for it!

Auckland area would be ideal but hey, anywhere considered!

Thanks guys
Mike
