81 gs750e ticking sound - opinion

[Techuser]

I've been looking for a gs750e to buy and came across an 81 local to me. When I went to look at the bike there was a ticking sound, seems like it's coming from the center of the engine. I posted a video of it out here: http://www.youtube.com/watch?v=TvN6pcmAeh0

The current owner said it is more noticeable once the engine warms up.

Is this a cam chain adjuster issue that I've read about on here, or something more serious ? I also read here that the 750 80-83 bikes had oil pressure con rod problems. Thanks for any advice.

Check this thread and see if the sound is the same, hard for me to tell, but it might be the same problem.

hi babes.
do ypu know about the trick ov listening to the engine with a long screwdriver...
start the engine...
stick the handle to the lumpy bit in the centre ov ya ear...
and touch the tip onto various parts ov the engine... this will give you a really good idea ov EXACTLY where in the engine the sound is comming from...
if its the rear then prob camchain or tensioner...
if its the front then maybe the tacho drive...
if its the bottom, probably the main bearings or clutch or gears...
if its the top, then probably valves, valve buckets, shims or camchain top tensioner gear...
but try the screwdriver thing as its really usefull...

good luck.

Sounds like an exhaust leak to me....hard to tell though, could be cam chain tens needs rebuilt.....hard to tell (hear) from the video.
