Rattle Sound Problem

Hello, I want to figure out where this rattle I have is coming from. It is a metal rattle that is random when climbing speed with half throttle. Its like a nut in a metal cup sound. Not consistent to anything and doesn't happen when parked and rev'ing the engine. my exhaust is tight and it doesn't have the stock headlight as some have said in searches I have done. I haven't replaced the chain on this one yet but it seems tight with about an 1" of play, so I am not thinking chain slap. If anyone has any ideas or has experienced this with theirs, any help would be appreciated.

Make sure nothing is rattling around inside your headlight bucket, pipe heat shields are tight, windshield and fender bolts are all tight and there are no NUTS IN YOUR CUP! Isn't that why you wear a cup though?

1. How many miles on it?
2. Where is the rattle coming from?
3. Did it just appear one day or get worse over time?

The rattle sounds like it may be coming from the mid section maybe engine area but who knows exactly when you are moving down the road. The bike has 8000 miles or so and seems like the sound has stayed consistent. Below is a picture of the bike for reference.

Have you checked your chain recently? If there's too much play you'll get a rattling sound. Also, check the headlight it will make a rattling sound as wind goes through. I would defer to Saifar he has the most insight.

The chain hasn't been replaced by me yet but I do check it and it has about and 1" of play. I just put this head light on an everything is seemingly tight with no rattle when i move the wires around.

The sound at times seems like its coming from the lower part of the bike so I have put pressure on the shift lever but still hear it. I may not be putting enough pressure on it to stop the rattle or it could be coming from the shift linkage itself.

At times, the damper rubbers on the counter balancer will give trouble and cause a rattling sound. You will hear it down by your left foot under the side cover if that is the case.

So this would be happening inside the engine? Is there a fix for this or is this not a big deal and just some annoying sound I am going to have to deal with? Thanks.
