The triples are wrong for 87. 86 forks were .75 shorter and have an aluminum cap. 85 and under has a steel fork cap but they are really not an issue unless they are pitted.
Are they 33mm tubes??
Plastic, paint tank, recover set, tear it down and powdercoat the 87 swinger red and do the frame while your at it.
A good used shock can be rebuilt if it's inexpensive. Contact Onformula1 for suspension....
Bill007 can get you nice air shrouds, not sure what colors he has. Hmmm, I could use a white set.
I love the 87 tank decals buried in clear!!
The headlight would be on the expensive side. A 350X is less rare but they run 200 to 350$ on EBAY but you have trike friends here.
I can't tell in the picture, if the rear axle has 5 bolts then it's not 86 or 87.
Personally, I wouldn't worry about the rims, just get 3 new tires mounted on thick rims if your gonna be in the rocks; Otherwise medium thickness is good.
If you have the book, adjust the valves, it takes 4 minutes. If it's low on compression, bore it and put in a 10.25:1 piston.
If you get into the clutch side, clean out that oil filter rotor.
87 has a fatter kicker shaft than 86.
Motion pro makes cables.
Lots of other calipers fit, such as a CR80 on the rear disc brake.
Anyone can get the key switch on 86 or 87 but a silver swingarm screams 1986.....
You've got 2 so you should be able to put together one nice one.
