CB900 Custom oil stopper on valve head - AOrhun_imp - 01-25-2021
Hi everybody,
I own a '82 CB900 Custom which I cherish.[/size][/font]
I had to do total strip down of Valve Head recently. Among other things I have seen the "Oil Stopper Plate"s (Part no 12241-425-000) situated on Cam Shaft caps B and C are in bad shape and these small parts are not available any more.
Does any one know the function of "Oil Stopper Plate"s (Part no 12241-425-000) situated on Cam Shaft caps B and C ?
What happens if I omit installing them.
Thanks for your inputs.
Best Regards
A.Orhun

AO this forum is for the modern 2010-2019 Honda CB 1100's but maybe someone will be able to answer your question.

Thanks for clarification I will try other user groups, but may be that `someone` can be found here as well??
PS.. Try older HONDA`s with carburetors seconding your CB1100`s, you may find them more engaging to ride and care for
I also own a`86 VF1000 FF.

Good deal!

AOrhun, glad you were able to solve the problem. When you have the pieces back in the head, would you please attach a picture or two of them in place so that we know where they go and what they do.
RE: CB900 Custom oil stopper on valve head - pekingduck - 01-27-2021
The rubber pieces, 12242-425-000 have not been discontinued by Honda. I think the rubber pieces were wedged between the cam bearing caps and the sides of the head to provide a bit of a dam so some oil stays in the right side of the head when the bike is on the sidestand. The 12241-425-000 stopper plates keep the rubber pieces in place.

I do not know what they look like on the CB 900 but the CBX engines had some oil baffles as well.
