    Rxp ignition timing

    Hey everyone. The RXP is almost done so I can stop bugging you all! Anyway I'm putting a 08 motor in a 04. I pulled the 08 PTO cover and installed the 04 CPS sensor (just cut the indent in the case for wires. I removed the encoder wheel off the crank and drilled it in the 4 o'clock position (looking at the back) so I could turn it 2 bolt holes clockwise (looking at the back of the motor). I just went to fire her up and BANG. Massive backfire. Can anyone tell me if I did something wrong (which obviously I did lol). How can I check the ignition timing? To be sure that's the problem?

    depending on what year trigger wheel you used you may have gone the wrong way when you moved it 2 bolt holes.

    I got the original trigger wheel out of the motor so it must be a 08 trigger wheel. i thought the trigger wheel was the same between 04 and 08?

    Your right.

    The original pin hole should be 2 bolt holes clock wise.

    The new hole you had to drill should be 2 bolt holes counter clockwise.

    Is that how you did it?

    Have a picture?

    If you have the 08 sensor use it go back to stock placement and just adapt harness that way you wont be the extra 7 degrees out of time.

    If thats where you drilled the hole and installed the pin I think you did it correctly. (7deg off of course)

    It should run.
