Yesterday was the first sunny day in weeks, I was riding my VTR1000F on old road with a smile on my face when suddenly I heard a massive rattle so I hit the kill switch and I rolled to a stop on the side of the road. The bike previously had a bit of timing chain rattle I've been meaning to replace the tensioner in it. Straight away I figured the tensioner had totally let go. The other theory was oil starvation from wheelies, it sounded more like a rattle than a knock but it's hard to tell with a helmet on. My mate rescued me in his ute and we pulled the rocker covers off and everything was still lubed and looked ok. One side was fine, the other had a limp cam chain and yep the tensioner was ****ed. The chain has skipped links, which means valves into the piston We pulled the offending head's cams off and sure enough the exhaust valves were bent. We pulled the head off and the 2 exhaust valves are bent as all shit but the piston looks ok but I've still gotta clean it up and look for cracks. Fingers crossed we can get 2 new valves, new tensioner and re-time it. I'm still on the fence about doing the timing chain since it looks like a huge job and the teeth look good (bare in mind this bike is a cheap shitter). I'm glad I switched it off with 2 secs of hearing the rattle. My mate is taking the head to his mates shop to get a price on the valve job.
