Timing

OK, I'll have a go BUT I am not an expert on GS500.
From what I remember, It's a twin engine.
Reference from GS1000 engine, so it should be simular.
Inlet cam, #3 should be pointing straight up. ^
Exhaust cam, #1 should be pointing fwd -
and #2 pointing straight up ^
Bottom timing mark should be lined up to "T" (NOT F)
The bottom timing mark is behind the right smaller casing on the engine.
If it has got a smaller bolt then a bigger nut behind it, turn engine over with BIGGER NUT not the smaller one.
Take plugs out to, to check one of the pistons is TDC.
I hope this helped, I have not worked on the 500, but any help is better than none. Phil.
Ps. You might be best to get a manual, oh! 20 links between #3 and #2 on 1000, might be same on yours.

The larger GS bikes (1000, 1100, 1150, etc.) are 20 pins on the cam chain starting with the pin over arrow 2 on the exhaust as 1 and the pin over arrow 3 on the intake cam as the 20th pin. On the 450's (and the 500 is just a later 450) the pin count from exhaust arrow 2 to intake arrow 3 is 18 (eighteen)

(this from memory and I no longer have a 450 manual, but I am reasonably sure it should be 18 pins)

#1 parallel to valve cover face, #2 facing straight up. Count Pin at #2 as first pin, pin eighteen will have #3 pointing at it. The notches in the ends of the cams will be facing eachother at this point. The nub on the pickup will be pointing at the mark after R-T. Not the mark just before F. Then crank the engine over by hand very slowly a bunch of times to see if anything hits.

I have a German 90/91 factory Suzuki manual that I could possibly send you but it is 12.6 megs. I don't read German but the pictures are pretty obvious.
