Engine treatment.....

I didn't take any snaps of the rubber iso mount and the nose ring arrangement. I have photos of those set-ups early in the thread

I've discussed the coupler arrangement before. It is molded (shaped to fit) from ceramic and Permatex Ultra Copper. The plastic tie wraps are plenty to hold them in place without melting (spun alumina is a great insulator). Should work well on YS exhaust too

The spark plug wire usually comes with a spring clip that is a total pita to work with. My solution is to toss the spring clip and add a short length of silicone rubber. It holds great but allows simple plug cap removal
