My Gen 1 has done 39K and developed cam chain noise, the tensioner was fine the cam chain had stretched & worn.
I fitted both anyway, £99 for chain, £33 for tensioner. Can't see the point in fitting none standard parts when genuine parts aren't that expensive.
How long did it take to change the chain? I think I will do the same in the near future. I just replaced my tensioner but before I put it in I measured from the top shoulder of the tensioner body to the 'screw' inside ( top of plunger) with the plunger fully wound out -this came to 11.2mm. After installing and releasing the new plunger then winding the crank I measured it again and guess what, it came to 11.2mm. In other words my tensioner is at full extent already. Obviously if the chain wears any more it will start slapping the tensioner -and it will inevitably fail.
Has anyone else changed a camchain?
Edit:- Ah, after dismantling the old tensioner I've discovered that the 'screw' stays in the same place in the tensioner body, it's not really a screw but a drive to turn the worm thread and move the plunger forward. Sorry if I worried a few people.oops
