Trophy silly questions but got no manual

1200 four trophy 1994,
First
.....fuel tap has an arrow/wedge shape with 'on' at the thin end. there's a mark on the fairing at 3 o' clock obviously to align the marks on the rotating tap. There is also on the tap, at 3 and 9 0'clock 'Pri' and 'Res'

when the wedge shape is vertical pri or res will be at the mark on the fairing, but 'on' is at 12 or 6.
if 'on' on the wedge is at the fairing mark then pri and res are at 6 and 12.
Pay attention at the back!!
Apart from the obvious pri at the mark means primary or full tank and res at the mark means you have selected reserve whats the 'on' got do with anything. ?

NOW !... Got all that ?

I am whizzing along with the tap in the pri position against the mark, and the red low fuel light comes on. I stop asap and the tank takes about 15 ltres, so it was still about a third full when the light came on.
capacity 25 lirts I think, or is that before 'reserve'---
should I have turned the tap to reserve, and just carried on Ive got ten litres at least, no?-----
on a tour I can't be bothered with worrying and I only need to know as in some bits of spain its a long way to the next gas station.
second...
generally suspension seems ok from a handling point of view, but definitely a pretty heavy klonk from the back if I hit even a small pothole or sunken manhole cover.... I don't think it's bottoming out, more like its, Im thinking, set too hard, like riding a hard tail.
The adjuster under the seat is set midway in the choice of five, and the increase arrow does what , exactly? soften or harden the spring or adjust the damping ?
I am solo, light luggage sometimes, 81 kgs about 13 stone (??)
A manual would solve all but I ain't got one yet.----- Thanks all

 

Thanx Dave and stevethegoolie Excellent replies. The suspension Im experimenting with today Obrigado.

 

Thanks too Gary..
the pdf manuals link doesn't do the 1990s Trophy...any other pdf sites I can try or any other ideas? any one got one for sale, even a photocopy ?

 

Ok some good some bad... fuel tap/gauge/red light sorted....great advice all...
Now back to the rear suspension..
The 12mm nut on top of what I guess is the gas damping, under the seat, ( does it have gas damping?) winds in or out and doesn't seem to make a difference....there's a vertical window that I thought was graded but nothing seems to change. the top of the gas cylinder , if that's what it is, has notches that suggest a c.spanner type adjustment system. Then I discover a four position rotary switch half hidden behind the RH side fairing that seems to be connected to somewhere by a Bowden cable and eccentric cam ...??
Post # 2 assertion that the thing under the seat sounded good til I got down and realised 'spring compression' can only be adjusted by the traditional stepped ring on the spring housing as used on almost every shocker for decades. Am I wrong? Thanx for your advice and patience all UJB

 

Thanks Sprint Dave the manuals you linked in #9 are great. answered many of my Duh... newby questions got to have the plastic off soon to sort some paint issues, will use its nakedness to get to know it a bit better.
