At both connections I used longer stainless steel bolts, a #10 SS washer, a stiff spring I found at a mom-and-pop hardware store, stainless steel bolt and locknut. If you look in the Bentley manual you'll see there's somekind of spring-washer setup for the connections I mentioned. I couldn't find them -- dealers, list vendors, muffler shops, etc., didn't have them. >> I recently worked on the exhaust of my 90 Westy and when assembling it, I used the old metal doughnuts which never seem to wear out, and I replaced all hardware with metric stainless except for the studs that were in the heads. I used about six SS spring washers (like a little potato chip with a hole) and a slightly longer bolt to approximate the set up illustrated in Bentley. I wonder if even more spring washers, and maybe on two of the three bolts, would help to dampen the flexing? Raul Cisneros, NY 87 Syncro W Westy 90 Westy |
