Re: Benelli TNT 600i - Owners' Reviews & Experiences
Definitely the chain tension-er and/or the timing chain slider. The spring on the tension-er is most probably gone and on it's last leg. Don't rev it too hard or quickly, if that spring snaps, you will lose the whole head, valve train and the pistons due to timing cam shaft skipping a tooth or two..
Get those replaced ASAP. It's not very expensive but time consuming replacement.
Also when getting the kit replaces, check the elongation on the timing chains. Workshop engineers can do that against manual specs.
Keep us posted friend.

Hi All,
Am from Chennai and am using the 600i from past 2 years, from past 2 months the bike is making some wired sound when the engine temp goes beyond 90 degree so I took to the service center and as per them i have changed the all the shims ( 16 ) and there was little valve leakage as well so polished the head as well. It took 20 days to get the bike but even after changing all the shims and polishing the head still i hear the sound ( its like some iron part is sniping inside the engine ) the sound will only start once the engine is warmed up. I will attach an video link can only help me out.
As per the service center its an issue with timing chain but the bike has clocked only 14000 km. Any help would be grateful.**
