Chain and sprocket in India
 

Hello,
I am currently near Delhi on my trip from London to Oz (see www.planitearth.co.uk). Whilst I changed it 15,000 miles ago, my chain and sprocket have had it on my BMW f650 GS Dakar and i need to get hold of one fairly urgently. I can get one sent from the UK, but does anybody know of a local dealer where I could get one straight away? In the absence of a replacement, I may gamble and hobble to Kathmandu.
Any suggestions much appreciated!
Charles
