flywheel magnet installation help 2004 gti le rfi

[NIL8er]

i removed the magneto cup and didnt mark it. Now im getting CPS codes and i think its prob due to the cup on incorrectly. Does it matter for the RFI how the cup goes on the flywheel? If so How do i do it correctly. TIA

The cup does not effect timing. The flywheel itself uses a keyway / woodruff to lock the flywheel in the correct timing to the crank. Unless you swapped flywheels? Not all Rfi flywheels are timed the same across all years.

is this just for rfis? and i may have switched flywheels due to motor swap from 2004 to 98 rebuild

Yes the cup controls the timing not the flywheel. If the cup isn’t in the right holes your timing will be off.

ive seen that . good info but not pertaining to my issue . thanks

How do i find the correct placement. I have another set up and will align the arrow on the cup with the place on the flywheel where teeth are voided like the other one ( around 25 degrees)clockwise to right of arrow???

 

[NIL8er]

I changed position of cup and all codes went away except
0335 (02 01 03) " cps no signal detected" (" fault code active when engine is not running and ignition is on ")
Fuel rail is pressurized.
Will run with fuel sprayed in intake
Fuel pump/ injectors worked on other ski
Fuel Pump on with key
Any advice ?
Seems injectors aren't being activated

Check your fuel pump pressure. Pull the injector rail and see if the injectors are firing as you engage the start button. There are several checks you can do from the Number 4 plug to see if all the components are withing range. Good Luck.

#4 plug? on the mpem?
this pump worked on other ski
they are firing, i pulled from engine to check

I have swapped out mpem and Bosch CDI. They both work in other ski.

yes in the manual, I'm pretty sure it is the number 4 plug where all the sensors plug into the ECU. I have a Flywheel if you'd like me to take a picture of it.

ill check out the manual but im pretty sure its a timing thing now because with tps reset it is starting for a few seconds but sounds off .
ill guess ill double check the rotary valve timing . i set it but
if its 98 -04 i think there the same so yea. thanks. i compared another one i had and all the cps fault codes want away but it wouldn't hurt to see yours.

 

[NIL8er]

Killed the starter. Rebuild kit on the way. Rotary valve is timed correctly. So idk.

Here ya go, not sure what year this one is. Pictures are marked and the numbers are marked and visible. Good Luck.

Only way I can use as a reference is if I could see where the lettering on the cup are in relation to the keyway or void on the flywheel assuming there all stamped in the same spot. The void on the flywheel and keyway on the crank shaft are fixed and have nothing to do with the cup other than trying to determine where the cup goes in relation to them. I can't see that from these pics. Thanks though.

 

[etemplet]

I took pictures of the numbers so you could verify you had the same flywheel. The void is marked in the pictures in relation to the key way. Good Luck.

Since there's no raised magnets on the rfi magneto does it matter how it's installed on the flywheel?

i appreciate that but what's most important is the magnet cup position in relation to the flywheel( or not, there's no magnets on outside of cup like on carbureted skis so does it even matter) only way to compare is to know where the specific lettering or arrow is in relation to the keyway or spot on the flywheel. Need a way to orientate the cup to the flywheel if even necessary.

Any thoughts

 

[mikidymac]

If there is no trigger pickup on the cup then it won't matter how it is installed.

 

[etemplet]

In the large picture I posted you can see the keyway, the gap on the outer rim of the flywheel, and the numbers. From the picture you can determine the position of the flywheel. Personally I'm more concerned if you have the same numbers and the flywheel is proper to the application. Like Mikidymac, I don't see how there is any relevance to the position of the magnet cup and time. I don't think the cup is something that is removed often from the Mag flywheel but it does no harm in checking. Good Luck !!

 

[NIL8er]

Yeah I'm convinced with the rfi it doesn't matter but you said it did. I'm no expert.
