What say we post recordings/videos/pics etc, of issues we face/see on the internet/neighbor face's etc here so that we can brain storm and find the underlying causes. I believe this'd be educative, interesting and spot on. Similar to the thread in which we guess which bike it is by seeing partial pics of it, though this'd be a bit more on the technical side.
Here's my contribution.
Bajaj XCD 135 L.e.d mod - YouTube
This a fellow Xbhpians XCD 135, if you pay attention you'll notice that theres a thumping sound, and the sound only appears in lower RPM's but vanishes as the RPM climbs.
Answer - The issue was diagnosed by psr sir, to be a wornout conrod bearing, causing the piston to slap the bore at lower RPM's and vanish at higher RPM's cause of the centrifugal force.
CRF230 Noise - YouTube
This is a random video I found online of a CRF230 a.k.a ZMA. Notice the wierd sound. The valve clearance was double checked and ruled out its something else.
Answer - Yet to be solved. Though I suspect a kaput tensioner.
