Thanks for the replies. I found the part number for the 05 cam chain but i was trying to find the DID part number itself, as I'm currently in Singapore and there's no Husaberg dealer here but they have a DID agent.
The Husaberg part number makes no sense to him and I dont have my old cam chain here to show him. Its also a litlle difficult as his english (singlish) isn't that good. Anyway so far I think i need to get a 66 link chain, so I'll go back there on Monday and try my luck again if I cant find the DID part number on the net somewhere.
Appreciate the replies anyway. Cheers.
