If you have a sleeve which has a solid metalic ( or graphite ) coating at one end my view would be that the woven end should be fitted inside the silencer after making sure that the split pipe end is spread enough so that no force is required.
Fit the graphite coated end facing forward so that the sleeve will hold together as you slide it on to the exhaust pipe. Use plenty of copper grease on all parts. This will help it bed together more easily and it will also help if you need to split the joint for tyre changes etc. Regards Roadster |
Just bought a non standard woven type seal off ebay that was advertised for the MP3 but it was not long enough to fully seal the slots so I had to seal them with an extra jubilee clip.
Make sure you get a genuine one although they are quite expensive in comparison. |

Just had another graphite ring blow out. Both times they cracked after riding through water. I'm tempted to use some muffler repair tape to build up the area in front of the graphite ring to protect it from getting wet and blowing out again. Does this sound reasonable?

[quote] That's puzzling. I've been through several floods and even forded a stream without this happening. Once assembled very little of the collar should be exposed and it should all be clamped up tight. Are you sure that you are inserting it fully in to the silencer? I can only repeat my suggestion that you should use copious amounts of Coppa-slip or similar non-setting copper grease. Put the grease under the clamp and on the screw thread as well. It all helps get a snug fit for a given amount of torque on the clamp. |

The first thing I did when I got my New 2016 Home from the Dealer was take that 80 pound weight off the bike for one of these. I love the sound as I don't have any DB Killers Installed, and no gasket to deal with...

23,000 miles on my MP3, taken the muffler off three times I think (maybe four), and still on the original graphite gasket. Got a spare handy, though.
I forget which way I insert the gasket... I want to say I insert it into the muffler, but with the mesh facing out so as not to be damaged by the four wings of the muffler when it is compressed, and wiggles around. I guess I hadn't thought about the end of the downpipe digging in. |

there seems to be several styles of gaskets that yamaha sold
this one seems like it would hold up the best. its made of copper. with what looks like asbestos for soft seal. cost to make them must have been higher. 2G2-14714-00 full graphite 3YF-14714-00 3YF-14714-00-00 |
