FLHTPI non adjustable timing? HELP
I am no noob when it comes to motors and bikes, but this one has me a little stumped. This bike is fairly new (to me anyway). It's a 97 Electra Glide Police Edition. I was pulling the nose cone off to swap cams and going through the process of marking the timing for the re-assembly process. I noticed that the timing plate did indeed have the adjustment channels to change timing, but the two screw in pillars were place in two round holes coincident with the adjustment channels. Aka from where the plate was set, it could not be adjusted. Is this a factory set timing or is something not right here? I need to do more research into the correct timing adjustment process and I plan on setting the timing soon. Is the timing set in the "correct" place and not adjustable so I don't have to mess with it? Some input would be great. Thanks in advance!
PS: I plan on installing an aftermarket ignition module eventually but for now finances say no dice

..... you need a manual for your bike, 'cause my evo experience in with an 88 and 95 models, both carbed
the plug on the left side motor case will reveal the timing marks on the flywheel.
the sensor can be rotated to alter static timing- but I would not recommend that.
I think your model uses a crankshaft sensor on the front left motor case by the oil filter and stator plug
you have the magnetti-marelli ( MM) efi which can be ...um interesting...
there are a number of ways to skin a cat.
Evos have a "single fire" spark- in which both plugs fire at the same time- 1 cylinder burns, the other is a waste spark- thats why only 1 coil is needed.
the crane hi4E allows dual fire spark ( adding a 2nd coil) and a number of advance curves, optional rear cylinder offset.
on carbed models, the ignition curve is also altered by the vacuum operated switch ( VOES) which is triggered from a port on the manifold.
VOES are available which close at different vacuum, or you can get adjustable ones.
But I don't thing the MM efi uses that
or you can stick with your stock PD module, it will have a higher rev limit ( 5800 I think, my 88 is 5800) and a different advance curve...in reality it is similar to the sportster module which many guys used in the 80's before the aftermarket took off.
there is also an evo forum here, for bikes that you can tune with your fingers and brain. no laptops.

Thank you for the response and clarification. From what I understand static timing is set by rotating this plate and that is why I made this post considering where it is set at now, it can't be adjusted. I know I have to get a manual. It's just an extra expense I have been trying to put off...haha Do you or anyone have any insight as to why this timing plate may be set in a non-adjustable position?

I just said screw it and took the time to set the static timing right. It was clearly as advanced as it would go and that wasn't right. I set it back to the recommended static timing
