Something to consider about the Speedmaster fender, it has a hole in the center about 2/3 back for a brake line clamp.
Speaking of brakes, I upgraded to a 3 piston Nissan front caliper and floating rotor and am very happy with the setup.
I have had the Spiegler brake lines for years. No issues, although the chrome is kind of flaking on the banjo fitting.
I have been running Nology coils and HotWires with iridium plugs for 30,000 miles or so, never had an issue with any component and it never seemed to bother my stock ignitor. I could swear that it ran smoother when I changed to it, but maybe that was in my head. Again, over 30thousand miles ago...
Progressive shocks are a great improvement over stock, I'm not familiar with the 444, but I had 412's on mine and now have 440's. Do the front also if you haven't already.
If you want to be rid of the pop on deceleration, unplug your TPS wire. Plenty of guys here run aftermarket carbs without the TPS, don't think that you will do any damage by eliminating it. I unplugged mine and the pop was gone instantly.
