need help figuring out motor tapping noise

nothing like a picture great dan :hihihi: :mrgreen:

I see now. I was confused on the oil port. I see that there are oil ports at both locations. I was thinking that there was only two oil ports per shaft. not 4.

That is why I told you look for the oil port under the spring to see if they are installed correctly. If you can see it installed the rocker is installed wrong.

The shaft I have right in front of me has 4 oil ports in a line. It is the only way I can see that the shafts can be interchanged from top to bottom and vice versa and keep the lubrication.

Yes all the oil ports are inline. If the ports are visible with arm installed it on backwards. This is possible as I have seen it done.

Since the rockers ride at different places top to bottom, when the shaft is swapped top to bottom the rocker rides on a fresh spot.

Worn rocker shafts??? Never considered that in the engine knocking thread, we only looked at valve float and weak springs!

I see what you are saying now, yes all ports face inward. In other words the oil is being ejected at the point on the shaft subject to the most load which is the side of the shaft facing the engine.

So who out of us GL1100 owners that have the illusive ticking is willing to tear down their heads and see if swapping the shafts will eliminate the ticking?

Not me, I just got mine back up after 8 months after snapping a timing belt and replacing the head.

I have an '81 engine sitting on the floor that hadsome engine noise. I can pull the shafts and at least measure them for differences and inspect them for wear!

This thread has gotten me curious and everyone here knows when I get curious......:builder:

I made a half hearted attempt at checking my rocker assembly yesterday. In this thread https://www.ngwclub.com/forum/viewtopic.php?t=32916 I was led to believe that I could just push the spindle shafts out without removing the cam holder, but it doesn't seem possible with the 1100.

I wasn't sure if backing the cam holder off to the point where the spindle would clear could damage the cam seals, so I gave up. I have no clearance in the rocker assembly that I can feel. Only the acceleration ramps and tip of the lobes are shiny, the deceleration ramps and base circle look like they are untouched.

I had read also the shafts will slide right out with the belts on but not true since the shafts have to slide forward out of the holder but the backing plate won't allow this so it seems the belt and cam holder have to come completely out.

Here is his tech tip on swapping the spindle shafts:

I was thinking maybe somebody holding the back of the cam in with a stick while I removed the holder and switched the shafts.

That sounds like it could work. I feel like trying it myself but I don't have the tick.
