That's what I'm running for those that would like to know.

The one I'm using is not an AC Cdi it's a DC CDI. Yes I'm aware it thinks the motor is spinning twice as fast I noticed it when I set the dip switches to the different rev limiter values it stopped the motor at half the set value for the rpms. I really appreciate your insight again this is not...

I did even with the new timing light it shuts off after midrange rpm but at 3k and below I'm now at 20 degrees advanced. I tried 15 degrees and it struggled to start. It would crank but not start. When it did run it didn't feel lively. Anything beyond 20 would cause poor idle low end and mid...

Runs great decent idle good midrange and killer top end. Thanks for all the help and insight.

I retarded the timing by 15 degrees by redrilling the mag cup. The idle is much better and the midrange too. High range is still insane. I'm going to redrill again and go back another 15 degrees and let you know if it keeps improving. Tomorrow I'll also have a new timing gun that hopefully works...

I installed a DC CDI not an AC one. My ski had a trigger coil for the DC setup so it was pretty easy wiring it in. I will look at the Polaris DC conversion thanks!

That's very cool! I took a look at the circuit and it's very complex way beyond my knowledge or basic circuits. I like the concept of reusing the start stop switch!

Guys I appreciate the insight I really enjoy tinkering and learning about these things. As far as safety we always ride in a group friends and family I would never just send anyone off alone into the ocean with an idea like this. I came here because I saw folks who contributed ideas and tried...

Awesome thanks yes I can confirm the mark on the PTO was set at TDC with a dial indicator at the mag piston. The timing gun was a cheap one and it wouldn't pulse at the higher rpms. I will try to get a better one. I can redrill the holes in the mag cup 17 degrees back and that will set the...

One of the first things I was did pull the front mag cover and I also pulled the flywheel and the mag cup pickup coil and key are good. I also made sure the timing plate was properly set. Thanks I didn't know it was 3.38mm right now I converted my 1/4" marks and its 44 mm BTDC. Here is the...

The pointer in the vertical threaded rod that's supported with the nut that's on the central hole the motor mount bracket has. Yes it's a screenshot of a video timing is at 37 degrees advanced at those rpms.

I appreciate the feedback but I know these little aftermarket CDI units are not great quality but I'm working with what I can afford. I set the TDC and the pointer every 1/4" is 5 degrees and this is the timing at idle up to 3k after that the timing gun doesn't flash but the engine still runs...

Understood therefore 47 degrees before the piston hits TDC the lobe of the magnet needs to be hitting the trigger coil. Basically my CDI has no adjustment so I'm trying to vary the timing by altering it's physical position in the flywheel.

Gotcha I understand but right now my static angle is 0 not 47. Technically my trigger lobe needs to be hitting the pickup coil 47 degrees before the piston reaches TDC. Therefore the light will flash 47 degrees retarded under 3k once it gets up to 3k it will flash only 17 retarded. Am I not...

I will go buy one and see what I got. Its a 20 dollar CDI and it's a simple build for my sister to cruise around so I wasn't looking for high end performance. When I hook up the timing light I'm supposed to get. 47 degree advance relative to the TDC mark of mag piston?

Thanks for confirming that's what I read on another thread. So I have two lobes on the mag should I set it to 47 degrees based on the start of the lobe or the end of the lobe? The carbs were just rebuilt and it's not running lean. If I slightly choke it it dies faster so definitely getting...

Hello, I found this forum recently and I saw some folks here have ran the seadoo engines on the Zelltronics CDI and I figured some of you may be able to help me. I have an old 97 GSX and I had a very erratic timing issue and it turned out to be the MPEM. I did a pretty cheap setup with a low...
