It's a done deal I am the proud owner of a 76 trident, It's not perfect but probably a #2 according to the guide lines. This thing sounds good. It's like the kid's speed triple but not as loud as his aftermarket exhaust but more throaty. I ususally do all of my mechanics myself so after looking this thing over there will definitely be a learning curve. I haven't worked on anything like this for a lot of years.
