I can't believe you're going to ruin it by getting rid of the fairing and seat.  Such a shame.
if it wouldn't  cost a fortune, I'd mail you the fairing and seat in a box full of broken glass and an exploding packet of glitter

... Luckily, I don't think it says Harley on it anywhere, so I should be good ;) my wife doesn't care to ride, so I'm going to ridesolo. See what I did there Cory...

I see what you did... wonder if I need to copyright the name I've used for somewhere around 30 years.   ;)  Bike is looking good, brother.  It was pretty nice when I rode it, but with some clean-up, tuning, and general attention it'll be a real sweetheart for sure.  That fairing is sort of an issue; it looks great and gives the bike a very specific personality, but it IS heavy and cumbersome and the thing has a much more agile and sporty look w/o it.  You're going to have to find one of these things for me so we can go out and terrorize the cornfields together!  As for the king n queen seat... get rid of that thing fast!

You can bet the front end springs are shot or about to shoot. Mine were progressive....as in progressively getting worse. I had to do them after that first trip up to the Meltdown. Mine had a luftmeister as well.

Pulled the top end apart to do push rod tube seals. Upon some investigation, the top end is a bit of a mod podge of parts from different years. Rockers appear to be 75 model, heads are somewhere between 70 and 74 and the cylinders are unknown, but I'm guessing not original being as they are standard bore with not much wear and 90k miles on the odometer. Probably a swap meet or parts bin special deal, but no worries, it will still work even if not "correct".

Also, the hardly ableson seat came in, and its much wider than I had pictured, but with the extra width from the saddlebags, I think it will do fine. I think minus the bags, it would look totally out of place though.

It is currently just sitting on the bike and I will need to do some fabrication for mounts

Looks like it will be comfortable, though!

The beauty of seats is only when you park it. Gotta have the comfort or you won't go 30 minutes without getting off. If you set it up right you could switch between that and a cool looking flat seat or something. I have an old s seat that would fit that stock tail fine. Just need some paint to match it up.

You could probably get the cover off the seat and trim some of the foam 'hips' off it.  Narrow it down a bit towards the seam without losing any seating area.  Just keep a smooth transition from the top to the sides.

Looking great either way.
"Quality . . . you know what it is, yet you don't know what it is. But that's self-contradictory. But some things are better than others, that is, they have more quality. But when you try to say what the quality is, apart from the things that have it, it all goes poof! There's nothing to talk about. But if you can't say what Quality is, how do you know what it is, or how do you know that it even exists? If no one knows what it is, then for all practical purposes it doesn't exist at all. But for all practical purposes it really does exist."
