850/1000 Valve covers

[Guest]

I had bought a nicely-chromed valve cover from ebay, for my '79 1000...went to fit it, and the bolt pattern was perfect; however, it was different in the cam-chain area. My 1000 cover has a wear plate to control the chain run between the cam-gears...my chrome one doesn't. Can I assume that this one is from an 850?
Thanks,
Hugh

Don't know

I don't know but you can tell by comparing the schematics which you can find at Alpha Cycle and many other places. I know both of my bikes use the same valve cover gasket but they are also different at the tops.

The 750 /850 head has a sprocket that bolts down to the top of the head instead.
That's probably what you have.

Yup...that's it. The chrome cover is contoured so that the cam chain is lower between the cam gears, where the 1000 chain goes straight across from gear-to-gear. Thanks much! I have the chrome cover listed in the parts for sale section for all you 750/850 buffs. Thanks for the clarification.
