My right muffler on the 91 VR is loose. I grab the tail pipe and the entire unit easily moves side to side 1/2 to 1 inch.
I've tighten the bolt to the frame, and I've tighten the clamp at the juncture point. It appears that the movement is at the clamp for the juncture point.
I've taken the entire right muffler off at the juncture point for the muffle and the end of the exhaust pipe all look good.
The nut/bolt and clamp has more room to tighten but it is tight on the muffler. To go much tighter I would break the bolt.
The left side is tight.
On my 89 VR both left and tight muffler are tight and snug.
Could there be a missing sleeve/spacer the goes over the end of the exahust pipe but inside the muffler?
Also I noticed 5 lub fittings while I was under the VR. Before I grease them are there any more? Also any special type of greese reommended?
