hey knowsalot when my 350x is runnning on normal temp. the engine makes some shhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh noise all the time even when i rev it, i didnt notice untill i let my girlfirend ride it and it was doing that, i dont think its a big issue but its starting to trip me out. some dude told me that it could my cam chain alittle loose and needs adjustment.but not sure. can u help me or anyone. what do u think it is?

 

I would like to help but any noise issues are very hard to figure out without hearing it first hand.

As for anything in particular to look for on the 350X that might cause this noise, I don't know of any.

If you have eliminated the noise being a small exhaust leak or an intake duct to the frame loose, then the camchain would be the first thing to consider if it is indeed internal....but a worn cam chain almost always has an intermittent sound that varies with engine RPM.

I would look very closely for an exhaust leak where the two headers bolt onto the cylinder head before anything. You would be surprised at what sounds they make sometimes.

 

ive checked everywhere, and its alright, but the noise doesnt sound lethal, its just a smooth shhhhhh noise that never quiets down its always doing that even when im revving it, couldnt be exhuast leak, mabe ill record the sound and send it to you so you can hear it clearly. if thats alright.

 

Sorry, but I can tell you without hearing it that it will be impossible to diagnose without hearing it firsthand.

I don't know how good of a dealer you have locally, but you should be able to have your dealer's service manager come out to your trike in the parking lot and listen to the sound and give you an idea of what you have going on there. Some guys are more willing to help to others. Not all dealers are like that and you should be able to find someone somewhere to listen to to it without you having to leave it in the shop.....along with an expected shop bill in return.

GoodLuck.
