Use the one stop method of using a piece of 8mm steel rod measured accordingly inside the tensioner between the worm screw and the plunger head. You will need to take measurements once the tensioner is under load by making a tensioner key. By using this method you get the benefit of using the original auto tensioner without the catastrophic damage if the tensioner fails, the tensioner plunger won't fully retract inside the tensioner housing.
Install manual tensioners , APE or other brand. Big problem also with the Firestorms ( 99% same engine) the automatic ones fail , specially front cilinder . Automatic ones = Russian Roulette....
On a daily bike i dont think its worth scrimping. Already lucky that it hasnt caused the chain to jump and damage valves and the piston. Best off buying new, maybe even manual adjusters.
Only removed the cylinder heads, as i said at the start i didnt know what the problem was as the noise was coming from the rear cylinder, if i had known it was a tensioner then i wouldnt have stripped the engine, but considering the bike has 96000 miles on it and i did all the work myself not to much of a problem, more a learning experience
Lessons learned , without expecting to hear nasty noises better to change the tensioners (preventative maintenance) , Thanks for the videos 👍
Thanks Cem, both tensioners will be changed, appreciate you comment
great to see you get to the bottom of the problem, and hopefully not too expensive
Cheers Shaun, You and me both! will be a few hundred £ just in parts, labour is free though

Thanks, handy tip. will keep that it mind if it ever happens again
Seen a lot of cam chain tensioners replaced it isn't uncommon. At least it other parts look okay.
Thanks Banditnev, want to have a closer look just to make sure, but the heads look ok

Appreciate the info
Result! 👌👍
Thank you! Cheers!
just replace the spring itself. much cheaper solution.
Thanks Leszek, with the age and mileage on the bike, i would prefer to replace the whole unit

@@bertzx9r894 New ones on order
So you removed the motor to change tensioner! Epic fail!
