Loose Headers
I noticed a little tapping a while back like an exhaust leak. I disregarded it for a while. Recently I drove my bike off a curb and I guess the curb was a little higher than I thought cause I hit my headers when I came down. The exhaust leak seemed louder after this and when I'd rev my engine with the clutch in, it would pop and sputter after I released the throttle. I noticed the headers were quite lose when I got home. Pulling on them where the 4 pipes come together, I could move the assembly about 1/4 inch. I was afraid I had damaged the mounts on the curb. I pulled the fairings and radiator off and noticed the threads and brackets were not damaged but every nut was quite lose and on one header I had lost both nuts completely. The bracket had slid down the header and was just hanging. This was obviously not from hitting the curb. Apparently the nuts had just vibrated loose over time. Every one of them. I bought 2 new nuts from the hardware store and some loctite. I applied the loctite and tightened everything up. Exhaust leak now gone and engine running smoothly again. I also put some exhaust sealant behind the nuts after tightening them to hold the nuts on if they did come loose again.
I'm curious if anyone knows the temperature range for the loctite. I'm afraid it's just gonna get cooked off. Maybe I should have used the sealant as loctite. Anyway, I'm also curious if anyone else has had this problem. Might be something everyone should keep an eye on.

The exact I mean exact same thing happened to me. I replaced the nuts with self locking (the ones that have a metal spring clip peened in). Mine wasn't leaking enough to make it run bad. BUT I did notice that when i tightened it back up the bike seemed to vibrate more.

No difference in vibration for me. Well, less if anything. Got rid of that nasty exhaust tapping though.
