Installing a Dyna S - Timing

[salty_monk]

Hmmm I have an even flashier model by that brand... so I guess mine won't work either.

What's the reasoning Ray? I would have thought that as long as you use inductive pickup from the spark plug wire then it should be no problem (unless there is too much "noise" from the other plug?)

I have statically timed mine using the advance marks so the light "just" comes on. If I keep moving the engine round the light comes on just before the initial gets to the line (a couple mm max so can't be a lot).

Dyna says to use the advance marks though... (not 100% sure the reasoning for that... maybe to make sure total advance is correct as that is the most important one..)

Anyone tried tuning by ear? Run it up a steep hill & listen for pinking....?

I degreed my cams in. You can choose whether you want top end/middle/bottom. It's your choice.
It's not that hard to do.
Degree wheel
Dial indicator
Spark plug stop to find TDC
I put the degree wheel on the ignition side, use the stator rotor bolt to turn the motor and the dial indicator on the side of the stator.

Read my easy to follow tutorial on the first page of this thread.
A degree wheel is your friend.

so tell us is degreeing cams a worthwhile thing to do on any bike?
i recall a joe minton articls from ages ago
and a naty vnce and hnes video that came with their degreeing wheel

Well that sucks First I have heard of this. Wasted $100.
How do you time for the 2-3 coil? I had to make marks on the rotor to be able to time it. Why didnt Suzi put marks on the 2-3 side?

Digital lights won't work with Dyna systems! Dyna will tell you the same thing. I have a high dollar, all the bells & whistles, Snap On light that is useless on everything I hot rod or race! Ray.

Ray how does a timing light now what is controlling the primary when you do an inductive pickup on the secondary. I assume I have a digital meter becasue it has an LED display with buttons

I have read this over a few times because I ordered a dyna s. Just got it yesterday, and installed it today. I went out and spent $100 on a timing light with the advance dials, I thought it would be useful. I ended up static timing it anyway.
But, strange thing, if I turn the dial until the 'T' mark lines up, the light says I have 20-25 degrees initial advance. Then I turn it to zero and the 'F' mark lines up confirming that it is at 12 degrees initial and when i rev it it goes to the third line exactly.
I am wondering if the 'wasted' plug fire is messing with the light?
Unless my light is defective, anyone else notice this? My light is an EQUUS #3555.

Lol you can say that again!!!

Now you know why Bill and I had such a long conversation about the Dyna

Here's how I did it.
Print out the timing wheel off the homepage of this site. Glue it to some straight cardboard.
cut out the circle.
Line the ignition timing up to TDC (T) 2&3. Without the Dyna washer put the degree wheel in it place. Use a coat hanger or something as a pointer. Attach the pointer to the clutch cover. Line up the TDC 0 to the pointer with the T 2&3. Turn the motor around until you hit the eight valve full advance. I think it's 36 degrees. With the mark on the timing plate mark the advance unit.
Double check the 1&4 advance mark (third notch) by putting the engine on TDC 1&4 and then the degree wheel at 0. rotate the engine until the full advance timing mark is lined up with timing plate mark. It should say 36?
While having a spark plug from the #3 cylinder grounded to the head make it so the plug fires when the advance is full by turning the rotor with your fingers. Use the mark you made earlier as reference for full advance. If the plug doesn't fire at all or before the rotation is complete rotate the trigger plate until it does so.
Now check the 1&4 by either using the existing full advance timing mark or one that you made to correct bad marks. Get the #4 plug to fire by rotating the rotor at full advance. If adjustment is needed turn the 1&4 Dyna trigger with that mini allen wrench supplied with the unit.
It's easier to do than explain.

I have a very fancy timing light but I have to double check it's not now a fancy paperweight!

I'm going to time it statically & then use the light to double check (both the static timing & that the light is working right!)

just to get me in the range when a plate is first put on I have the #4 plug wire off and a spare test plug in it.

turn the engine over with a wrench and the key "on" after it is all pluged in fused and all.

the plug right in front of you will flash a spark as you turn the crank back and forth lining up the 1-4 F mark

then you can get it started and time it on a strobe timing light.

degree timing lights are frustrating 'til you get to know how to set 'em.

I had to go back to the manual to get the ign timing numbers after I DE_TUNED my bike on a dummy day. I set the light at 0 and lined up at the the F mark. no no no no. I have a love hate relation ship with my new fangled degree timing light.

this is how it is done- 0 on the T mark good 12 on the F mark good set it at 32 and rev it up over 3K see the line line up and go back down

yeppers runs much better now

Do you have access to a regular timing light ?? Check it while running...

Makes sense & matches what I did last time... I guess those damn pictures of Bill's are making me a little more cautious this time around
