Valve sticking ? Pinging sound when turning over

Postby jessadr » Fri Mar 23, 2012 10:58 pm



'81 Gl1100 been sitting for the winter in my shop. It would turn over just fine when I put it up. New battery and starter. I had front engine cover off to change belts . Had carbs off of it rebuilding. No way anything got in the engine. It had some water in it when I got it last year. Oil has been changes 2 times . All the water seems to be out of the engine. I dranined a little out to check.
The carbs are ready to go back on so I was just turning the engine over clockwise by the crank bolt. It got to a place and stopped. I pulled the plugs and poured some oil in the cyl's. I left them out to not hydolock it.I removed the stoppers out of the carb holes I had to rock it back and forward to get it pass the hard place. When it passed the hard place it makes a ping sound out of #3. I am able now to turn it over by the crank bolt but it still mades that ping everytime. It is not as loud now. Has anyone had this problem with and engine that has had water in it. I am wondering if the exhaut valve might be sticking in the guide becuase #3 was the only cly that had rust on the old plugs and #3 carb was not as clean as the other 3. I am going to keep turning it over and maybe get it to stop that pinging. This happened over the winter sitting. I don't want to pull the head if I don't have to. There is still alot left to do with this one. Ever had that happen to you before.?

Sounds more like valve hitting the piston slightly..back off the tappets and see if it stops pinging???

Yea,I'd be double checking the cam timing.3teeth off will tap a valve.
Might as well pull that valve cover to help identify what and where.
The next thing is a compression test.Even by hand,you should feel compression in each cylinder.
If you bent a valve,even just a little,you won't get any compression in that cylinder.
Could just a stuck valve cause this?...yup,shure can.

Thanks guys. The timing belts were replaced by Honda in 2006. They look good, I will for sure check timing. And pull valve cover.
This is my first Wing. Any advise is very welcomed.

You might also pull the intake runner for that cylinder.it's possible it filled with water and rusted the intake Valve stem.on turning it over,the valve stuck open.rocking it back and forth knocked it back enough to clear the piston.It's really worth a look and you don't have to remove the carbs to find out.if it is rusted,you may have bent the Valve.only a compression test or leak down will tell

Removed right hand valve cover. I was checking the loosness of the rocker arms and found the intake on #1 had a cleance of about 1/4 inch. The valve is stuck down. The valve will open alittle more as I hand turn the crank but will never return to the closed postion. I turned the crank til the valve wound would be normally closed and filled the hole full to the top with engine oil. I would guess I have a bent valve but the cyl is holdind oil, no hole in piston and the motor turns over freely so maybe it is just stick in the guide. There was no milky oil in the cover. I am going to let it set tonight and go get some Marvel Mystrey Oil tomorrow. It will work wonders I hear. I looked in the intake port and it is very rusty but no bad shiney places on the valve surface Maybe a good sigh. Guess I had better start looking for headgsk and stuff maybe even a good head.

As you can see #1 intake valve is bend. I haven't pulled it out yet, but I am sure it was stuck due to rust that was in the cyl that I thought I had flushed out by filling all the cyls with oil over the winter. Should have loosen up all the rockers before even turning it over. I had good compression in #3 #2 and #4
#1 and #3 were very clean no marks on #1 piston and guess it is intake valve and head gasket time. If anyone has them just lieing around and want to sell let me know I will lap the other valves and see how they look after I clean the head real well. If the seat looks marked I will just have to find a used head. Sorry if the pictures are too big. This is my first pix post
