Ignition timing with Dyna S

Hey all, I just installed a Dyna S yesterday and the bike has been running great ever since. I adjusted the plate 75% counter clockwise, which I am estimating to be about +6 degrees advanced. The bike has low end torque like never before, but near the upper range of the power band, the power comes to a stop.

That being said, i've decided to let the bike sit until I get the timing adjusted properly. I've read that 32-34 degrees is where the 16v gs1100 motor should be. I was planning to rent a timing light from autozone to do the job. Ive never set timing before, is there anything I need to know first or be cautious of?

Thanks
 
Open the ignition cover on the right side of the engine so you can turn the engine by hand

take the #4 spark plug out and put it back into the spark plug wire. let it ground out on the engine. ( you can use a spare plug instead)

turn the key for the ignition "on" -- turn the engine with a wrench or socket and breaker bar -- not a ratchet

watch the spark plug for the blue spark and align the#1/#4 "F" mark and the pointer line when it fires...

that will be stock setting which ends up being 34 at full advance /// and 13 at idle
 
I'm not sure how that works, because I don't believe the Dyna S plate has any markings on it.
 
You have timing marks on your mechanical advance and a notch on your inner ignition plate.

Right, but don't I adjust the timing by rotating the position of the dyna plate? So how do I line that part up?
 
You rotate the plate to get the plug to fire at those timing marks.
Search "static timing"
 
Oh, got it. That makes sense. Sorry about the dumb questions, i've just never adjusted ignition timing.
 
I got the timing lined up exactly. The engine now runs smoothly like it should. This motor makes a lot of power, its almost a shame that it's only getting another month of use.
