While checking over carbs to fix a sooty left side sparkplug, discovered left side header not hold tight at rose nut to head. These are pre-balance pipe headers with a flange and I've fitted the longer type rose nuts. Head has a alu-bronze thread sleeve that is in place and very solid. No matter how tight I make the rose, the header still rocks side to side. Tried either steel or copper exhaust crush seals, no difference. There is enough movement to permit the header to rattle against the side stand nut or tang at certain lower rpm.
Any ideas what to check? Thinking to try wrapping copper wire around pipe flange to help nut compress more evenly...
