Here tell me what you guys think....
When I'm accelerating hard I hear a sound coming from what sounds to be from the top of the motor, valvetrain etc. It almost sounds like when you're missing one of the front fender bolts and the plastics rattle at high speeds, but I've checked those bolts. I recently did a valve clearance adjustment, but I don't remember if it made the sounds before, so it may have something to do with that. Let me know what u guys think or if I'm missing any neccesary info.

I need you raptor experts to help me out here.

 

Maybe you got some crappy gas, sounds like it's pinging.

 

Do you have stock exhaust with heat shields? The heat shields tend to rattle at higher rpms if just alittle loose. I also had my front plastics rattle by the gas tank. I found it by pushing the plastics when I was going. Just trying to think of some simple things before you tear it apart.

 

Have you got skidplates?Mine did that too when I got it new,it turned out to be the skidplates were loose and rattling...
