XR 500 Please help!

[350Xrider]

Hey, I have a 1980 XR500 and I am in desperate need of a scan of a manuel that shows the proper line up and marks for the valve timing. Any Help would be greatly appreciated, I have been needing this info for some time, but I realy need it now. Thanks

There should be marks on the cam gear that line up with the head or a mark on the head (lobe's down). And a mark on the fly wheel "T". With all that lined up put the cam chain on..
