Rattling Noises at mid rpm...

[buellbandit]

So im getting some rattling in the mid rpm range from about 2500-4000. Its worst under mild deceleration but i can hear it even on slight acceleration. I had the local dealer check it out and the concluded that it was probably the lifters and or the timing gears. So since it was still covered under extended warranty i had them tear it down. They found and replaced the lifters and the entire front cylinder and piston because it was slightly pitted. This repair took a grand total of 7 weeks to finish during which i lost half my summer of riding. Upon getting the bike back i have noticed the the rattle is still present. Has any one else experienced such an annoyance? My bike is an 04 xb12r

I've experienced the same thing at the same rpm range. It started getting a lot worse as I put more mileage on the bike. I'm in the process of fixing it right now. Pics and info can be found here: http://www.buelletinboard.com/forums/showthread.php?t=11420

yeah its sounds like the primary; check ur clutch adjustment; if possible suspend the rear wheel,run it thru the gears,try to duplicate the sound and pinpoint it.

Hopefully, adjust the Primary chain and that may be it.

I hear it sometimes but my bike has 20,000 + miles on it (05) and usually happens in those rpms when the gas tank is low. Guess the slight echo adds volumes. I just figured it was low gas cause I can't hear it after a fill up.

got a bolt or a nut in your tank [confused]

Possibly but I hope not.

The noise is all the time, gas tank full or empty. Im pretty sure its not the primary chain i have adjusted that and so has the buell tech that did the repairs. I think tattoo 72's fix is probably my problem or something in that general area. i know they didnt take the cams out so i know that they couldnt have seen in to those bearings like tattoo did. thanks for all the input guys.
