Leaking air from the head


New Member
There 2 o rings on this parts diagram that I put on and now this head has a leakat the metal gasket. Any idea if they are needed or what I did wrong ? They are in the right spots. Not sure why it would be leaking. Heads not warped. Or uneven.

WHY, did you put the orings on?
Did you have the head off for some reason?
Did you have a reason to remove the head?
Did you rebuild the engine?
Did you buy the correct parts from Honda?
Do you have a reason to think the orings are causing the leak?

We need more info. We'll take all you're willing to share.

Parts diagram says they go there. I completely split the cases, redid the gaskets, fixed the shifter forks, all that stuff. But I'm wondering if there are of any significance, I personally am not seeing one.

Ok so... I got the bike running. Yahoo! But...is just pouring out oil from the front sprocket seal while running. Wrong gasket on case perhaps?? This was a cheap gasket kit so I'm wondering about the exact match on that side of the case. It looks like the seal for the sprocket is wet.
