Last night I finally was able to do it: The last remaining orange part on the bike was the front fender and I yanked it out, replacing it with the wrapped blue fender. That was the very last orange bit on the bike (other than the atrocious overspray, of course) and it is finally gone.
Other things that needed work: There was some sort of relay or something that was wired in to the rear trunk brake lighting that caused the bulb on the right side not to light. I ripped that out and returned the wiring to stock and everything works. The seat and the faux tank are bolted in securely, and I applied some more PVC cement to the left side cover mounting pegs.
The front wheel swapped fairly easily but I found some weirdness along the way. The speedometer gear on the ’84 Aspencade wheel appears to be totally identical to the one of the ’87 Interstate. I don’t know if going to the digital box was a later change or what, but I left the ’84 wheel as it was and mounted it up. Getting it to mount, however, was a slight challenge as the brake rotors on the ’84 wheel were both vented discs which made them much thicker than the ones on the ’87. The caliper brackets have grooves cut in them to clear the rotor, but the ’87 brackets needed some clearancing to fit the older rotors. Fortunately, the ’84 caliper brackets were tucked away in the corner, still attached to the forks of the ’84, so I pulled them off and swapped out the brackets. Worked like a champ.
The radiator is refilled with new coolant, and I’ve begun to re-assemble the front fairing. I need to swap the locks on the faux tank and the fairing compartment — but I’m not sure if the lock from the ’84 fairing compartment is still functional. I may just wind up having two keys on the ring. We shall see. It certainly isn’t a priority.
Next up, I need to get the oil changed and swap out that seal. After that, it’s just getting the other mirror on and playing with the fairing. I am short one of the windscreen bolts so I need to source a new one, and then I can put the front together. Still left to color change, though, are the fairing edge trim bits and the little vent covers for the lower fairings. I don’t need either of those to be able to move the title and register the bike, though! I’m fairly confident that I will be getting a license plate for the bike in the early part of next week.
