Author Message   Is11b1p Posted on Wednesday, April 29, 2009 - 07:03 pm:        Motor is making noise. When I'm in 4th or 5th gear cruising along and hit the throttle I can hear like a clanking noise. Its only for a second then goes away. I have no clue what it is. Any ideas?   Bikerjim99 Posted on Wednesday, April 29, 2009 - 07:57 pm:        Try checking your primary chain tension.   Tdman77 Posted on Wednesday, April 29, 2009 - 08:35 pm:        When the nut fell off the front exhaust header bolt the other one loosened up and cause the flange to hit the header. It was strange because it only did it at certain rpms and gears. The noise was like a metallic clink, I thought it was in the valve train at first.   Is11b1p Posted on Wednesday, April 29, 2009 - 08:41 pm:        How much play if any should be in the primary chain?   Kalali Posted on Wednesday, April 29, 2009 - 08:45 pm:        This is probably not the noise you are talking about but if you are in high gear (like you said) at a low engine RPM and hit the throttle all at once, you will hear the valve train due to lugging the engine. Just a thought.   Is11b1p Posted on Wednesday, April 29, 2009 - 09:09 pm:        I checked the tension on the primary chain. The chain moves about a half inch. So I don't think thats it.   Is11b1p Posted on Wednesday, April 29, 2009 - 09:12 pm:        Stupid question. If its the valve train making the noise. Is there a need to worry about anything?   Pkforbes87 Posted on Wednesday, April 29, 2009 - 10:55 pm:        "you will hear the valve train due to lugging the engine." I'd love to hear an explanation of what exactly is happening when this noise is occuring. I hear it in my car fairly often, mainly due to not having a tach and the fact that the exhaust + engine noise is nearly silent. When in high gear and the engine is put under a low rpm load, is that "lugging" sound evidence of something bad happening? Will it cause damage or accelerated wear? Just curious..   Kalali Posted on Thursday, April 30, 2009 - 08:04 am:        I could be wrong here, but to be accurate, the sound is really not as much the valve train but is more the sound of detonation due to poor combustion resulting from too much fuel too quickly and the engine can not burn it effectively. I don't think it is a good practice to run the motor like this due to excessive carbon build up. The valve train only "transmits" the noise. Sorry if I am off base here but I would have to blame my buddy mechanic for that.   Buellistic Posted on Thursday, April 30, 2009 - 09:40 am:        BUELLers: "ECONO" noise listening tester device: 1(one) long screw driver How to use: Place handle up to ear an touch tip of screw driver on different positions on engine to listen for noise or noise changes ... MAY THE LONG LASTING BUELL BE WITH YOU !!!
