upper timing guide

[Guest]

I have a 1982 GS650G ,have been going thru bike.Have noticed upper end noise i thought was excessive ,when did vale adjustment all were tight (low miles) 10,000k. Noticed a few chain marks on inside of value cover (center top) looked in parts diagram and its missing the guide that bolts to the bottom side of value cover.My problem is I cant find one,listed as obsolet.. Part number 12782-49140 changes to new number 12782-33200. This guide is used in many different models , 550,650,1000,1100. Any help of where to locate new or used wood be helpful. Thanks Jeff

Any of the parts suppliers should have it. Partzilla lists it.

I wouldn't worry about the change in part number; that's standard practice for companies that retool, or change manufacturers. Just order the new number.
