Static Timing
« on: April 19, 2012, 08:35:05 AM »
Ok, I got the dyna s installed but I am having trouble with the timing instructions. I am not sure what holding the rotor in the fully advanced position means? I rotate engine and the light does come on but then I am not sure what to do next. I have followed the instructions and always end up in the same position. Please help.

Don't worry, everyone get this step wrong. You need to manually twist the advancer shaft to the advanced position as if the bike were reving higher. Then set timing to the advanced position. It's a bit tricky because you need to hold the advancer with one hand and then turn the base plate with the other.

You might also want to re-check timing with a strobe after you're done to double check. Rev the bike up and see if the advance position is hitting correctly.

Opening up a dead thread, but I'm having trouble setting static timing, and I'm having trouble figuring out the instructions too. 

After seeing this thread, I tried to hold the advancer shaft to the advanced position and then tried to set the timing, but I was not getting anything.  I checked to make sure I was getting power to the dyna s through the red wire and got 10.75V. Also checked continuity from the dyna s to the blue wire connector just before the 1-4 coil and that checked out.  So I set the dyna at an arbitrary angle, held the advancer shaft, and rotated the crank but my multimeter read 1.15V no matter what position of the crank. Then I set the crank at the 1-4 advanced timing marks and tried to rotate the dyna s, but still the same 1.15V. I am checking the voltage with one multimeter wire contacting the blue coil wire bullet connector, and the other clipped onto a cooling fin on the engine.  Is this correct?

I am trying to do this with a multimeter instead of a check light, and I am expecting to see something in the 10-12V range when I get the timing right.  I also do not understand why the dyna is supposed to be set and the crank rotated.  It seems like leaving the crank in the correct position and rotating the ignition until it's correct would work too.  I've never adjusted the timing on this bike though, so I do not know. Am I going about this the right way?  Is there something that I have way mixed up? Thanks for any help!

What you need is a strobe light.  Go to yard sale or swap meet, you might find them for 10 bucks. 

Start the bike up, rev and hold throttle to about 2500 rpm, check the strobe and be sure it flickers at full advance mark

I'll definitely check it with a strobe as soon as I can, but right now I can't start the bike at all, so don't I need to get the static timing right, or at least close, to get it started?

Adjust the plate to be right in the middle, bike should start, then use strobe and adjust plate CW/CCW accordingly

Well it turned out that the two wires from the ignition were marked incorrectly.  I saw another post that suggested this and tried it out, now the bike starts and I got the timing set with a light.  Thanks for the help.
