Hey guys, I'm new here and I'm having some trouble with my bike. I like the knowledge and friendliness displayed by the members of this board so I signed up here. Hope you all can shed some light on this.

So my bike is brand new, 2 weeks old and less that 380 km on the odo. Last week at around 200 km is started making a slight grinding noise. At first I thought it was the drive chain, so I adjusted it and lubed it and the noise was still there. At 300 km on the odo I adjusted my valve lash as per the service manual (.06 intake and .10 exhaust). The engine runs smoother (the valve lash was way off spec so I'm not sure what I paid my dealer a "set-up" fee for) and the valves tick away happily, but the grinding noise is still there.

As the noise became louder and louder over the last few km, I was able to observe its only really present at speed, and mostly when holding a constant speed or decelerating. This led me to think the problem is my timing chain. I tested this theory by removing the automatic tensioner and manually adjusting it a few clicks in. I put it back in, fired up the bike and went for a short ride. The valve chain being tighter bogged down the idle and slowed down the bike, but it did drastically reduce the noise so my conclusion is that the cam chain is at fault. I did pull the tensioner back out and install it correctly (backed all the way out and letting the spring tension set the tensioner) and the bike runs fine, smooth and pulls strong but the noise is ever present.

I would like to know if any of you have had this problem? It doesn't seem right that a new motor needs a timing chain so soon. While I do ride my bike hard, I do not consider I "beat" on it. I always allow it to fully warm up before I show it revs north of 5-6k, and when I do go full throttle it is only for short acceleration spurts, I have never continuously run it wide open for a significant amount of time. That being said I do weigh 300 lbs (which also means I do need suspension work but that will be another thread) and I do love to downshift and engine brake (meaning I do it at every stop sign and light). Could this possibly stretch a chain that quickly? Once I replace it should I expect I will not be able to engine brake and ride my bike how I like in order to keep the chain in good shape? Or do you guys think I just got unlucky and got a bad chain? If it's the former then sadly this bike is not for me and I just wasted 3k on it (yes it was an impulse buy and no I did not do my research on pricing when buying so my cousin and I got a little screwed, yes we bought 2 of them at that price).

I will change my oil again this afternoon and report if I find any shavings in there, but seeing as how the bike runs well and pulls strong I do not expect it. I would like to change my chain asap so that I do not have it snap on me and make a mess. Without taking the motor apart and having a look, other than the chain and tensioner plate, what do you all recommend I change?

Looking forward to your responses, thank you for your time.
