ignition timing for gs1100e

[JUSS10]

ok so i did a valve adjustment on my gs1100e and in the process of pulling off the ignition cover on the side to turn the crank, i saw that the screws that hold the sensors for the CDI have been cranked on. SO i would like to check the timing with a light but the manual I have doesnt seem to have the timing specs. does anyone know what these are? there has been a lot of rigged things on this bike so i don't doubt the timing has been tampered with. any help would be appreciated. thanks

What year ? My 1983 book shows 12 degrees BTDC at 1500 rpm +or- 150 rpm then goes to 32 degrees BTDC above 2300 rpm +or- 150 rpm. With a timing light the "F" mark of cylinder 1 and 4 lines up to the index line below 1500 rpm.

if its a stock trigger plate..
twist it full counter clockwise.
the factory didnt build in more timing then it could use or enough to hurt it.
if im ass-backwards on which way to rotate the plate someone inform me.
now on the pre-80 (points type)suzuki's...
thats a differant story..they must be timed.

Counter-clockwise will advance the timing.
There is a space on the top left under the ignition cover where you can see timing marks. Remove the top screw that holds the timing plate on. There is a timing mark on the plate and one on the ignition. Line these up and go.
If you want to use a light at idle hook into the #4 plug wire and line up F1&4 with the mark. Hit the throttle and it should advance to the next timing mark. They should both be spot on or your advance isn't working properly.
