Ticking from motor, need some help

Postby WrenchHead » Mon Oct 05, 2015 12:12 pm



Hey everyone,

I am new here, but have been looking through this site for over a month. I have been riding/working on bikes for almost 20 yrs 9I am by no means a mechanic or expert though lol) :D . This site is awesome by the way.

So I bought this 82 GL1100 for $500 CDN a couple of weeks ago. It ran good when I went to see it and sounded strong, the PO was not sure of the mileage as the gauges had been changed out. Picked it up and started to drive it home. As I was driving a noticed it had sort of a hesitation and a small tick that was not very load and I only heard it when i revved past 3K.

I took it on the highway and it seems even more hesitant, it was not pulling how a 1100 should pull in my opinion, I was in 5th gear doing 100 KM/H when there was a backfire and I lost all power and had a ticking coming from what sounds like the right side.

I limped it to the nearest parking lot, the bike still drove ok, but would not go much faster then say 40 KM/h and would not rev past 4K. I managed to get it back home last week and started looking at it.

- Checked the cam timing, and they are set correctly. There are no teeth missing on the cam pulleys and the belt is looking fine as well.
- Ran the motor for about 8 secs and checked the headers and all 4 are hot meaning there is no dead cylinder
- Water pump looks to have been replaced at some point and is in good shape
- I took the right valve cover off and there isn't anything jumping out at me that looks broken or loose
- The coolant and oil both look and smell fine (no oil in coolant and no gas or coolant in the oil)
- Turned motor over by hand a few times and nothing is binding or hitting or anything, it turns over pretty smooth

I am wondering if my carbs could be out of sync and causing the primary chain to be making noise? I have a video link of how it sounds below. It still starts up fine and runs other then the ticking.





Thanks
Shawn

Wow. That sure sounds like valvetrain - is it coming from both sides? Can you localize the sound better? It's hard to tell if it's coming from the valve cover area.

It's possible that the tick is also an exhaust leak - a backfire could have blown out a gasket or a rusty area and caused a small exhaust leak. Small leaks in exhaust can often sound like a loud ticking noise.

It definitely sounds like valve noise to me.
I would adjust the valve clearances. The engine needs to be stone cold to do it.
Here is the tutorial:

Thanks guys,

It is coming from the right side if you are sitting on the bike, I was thinking valve train as well. I checked the exhaust and there was no noticable cracks or holes or anything in the headers on either side. i can take the exhaust off though and replace the gaskets after I try adjusting the clearances on the valves.

Thanks for the input

Definitely do a valve adjustment first. That's what it sounds like to me.

With simptoms like sluggish performance, popping, limited rpms, and ticking on the right side, my guess would be fuel pump.
You may be able to pinpoint the noise with a auto stethescope, or another listening tool such as a long screw driver, wooden stick, or that sort....

That's a good point. You could remove the fuel pump (the bike will run for a short while without it, as the float bowls have fuel in them) and see if the ticking goes away. Best is to use a mechanic's stethescope (or similar) to find the exact source of the sound.

Thanks for the advice guys,

I am getting a mechanic stethoscope tonight so I will try and remove the fuel pump and run the bike and see what happens

That's the sound of a piston hitting a valve, I'm 99% sure! It may be just kissing it, which is why it's still running.

'Impossible' is just a level of difficulty! The only stupid question is the one you didn't ask first!

I would think that the timing belt has jumped at least one tooth, but probably no more than two.

So, what 's the verdict? Did you find it or still working on it?
