The top of the fork showing the adjustment screw and cap.
The bottom of the fork showing what looks like a plug of sorts. I don't see anything for adjustment here.
The triple clamps, I doubt these are original 1987 triples.
The front brake (left side). Could a 1987 brake be attached to these inverted forks?
The right side (brakeless fork)
A rear shot of the brake, maybe this will help someone identify the forks/brake.
