- July 01, 2013, 20:43:46 PMAre you speaking of stock exhaust? Mine is hanging off the bike in storage, I can't look at it. But I'm guessing the screws you speak of hold the baffles or some other internal components in place. What type of heads are on these screws? Hopefully, they're hex heads?
If you can't get inside to hold the "nut" they're turning in (or whatever threaded piece is turning) then I have a tip that could help. If they're turning inside, then perhaps if you tried to tighten them with an impact wrench (if they're hex heads) or a drill (if they're by chance phillips). The idea is to try to spin them fast enough to get them tp tighten into the "nut". Sometimes you have to repeatedly start/stop the impact - the sudden starting to turn is what makes the bolt turn in the nut, rather than the nut just turning with the bolt.
Another idea is to somehow pry on the head of the bolt/screw while you tighten it. The pressure you put on the "nut" can sometimes hold it in place while the bolt/screw turns, and thereby tightening it.
Hope that helps.

- July 01, 2013, 19:40:43 PMCan someone tell me the use of the metal screw in the exhaust pipe. There are two, one in each, the front cylinder and back cylinder pipes. The one on the front pipes is underneath the horizontal part of the pipe in between the two colar that are holding the heat shield. It is really on the underside of the pipe. The one on the back pipe is less obvious. It's near the muffler just beside the rearest colar of the heat shield, you can see it by looking from above the pipe.
The reason that I ask all this is that one of thoses screw has come loose and is vibrating randomly. It is so noisy that for two days I was sure that I had a problem with my transmission. I tried to remove the screw but it's turning loose in place without coming out. I tried pulling while unscrewing but to no avail. I was thinking about cutting the head off but that would leave me with loose parts in the exhaust that I would have to remove. Tought about soldering in place.......but would like to know the use beforehand.
Sorry for the long post for such a tiny but noisy problem!
