I have a 75 mkIII with about 32000 miles. I'm now getting a chainy sound from the primary case while the motor is decellerating below about 3000 rpm. Is this chain whip or resonance thats mentioned in some earlier posts?
I'm considering a new triplex chain and/or adjusters. Any help troubleshooting would be appreciated.
The clackety clack off idle happens when the hydraulic tensioners pump up. Since yours doesn't make the noise, the tensioners can be assumed to be working properly.
I am not familiar with the chainy noise you describe.
There are numorous gears in there along with a sprag.
Does your E-start work?
I would definitely tear down the primary and have a look.
