HPI CDI mini rotor ignition system for puch tomos sachs and derbi
PUCH HPI CDI mini rotor ignition system



new HPI CDI mini rotor ignition for ALL puch mopeds, E50 - ZA50 whatever ya got. so this new mini external rotor is actually lighter than the HPI internal rotor!

this version has an integrated 60W light coil for super bright lights!! great curve and comes with all you need to make the change. plus you can adjust your stator anytime even with the flywheel mounted!

+ remember this will mount up to any other moped with the same taper as puch, with a little work maybe, or no work. it might install itself. but try with tomos A35, tomos A55, any derbi moped, sachs, peugeot with cdi crank, motobecane? maybe yes and more...wait there is more! fits on zundapp and kreidler oh man what doesn't this fit on?! also fits on derbi GPR even! wow who knew? need info on this? yes you do so look here!

uses a 27mm x 1mm left hand thread puller!!!!!

always use a resistor boot or resistor plug when running a cdi or you run the risk of burning up your cdi box!

the trail tech voltage regulator works the best with the mini rotor!

the stator may be black, red or gold, champage, orange, pink, purple, or manilla envelope color. whichever color HPI sends out. its not something we can choose, so its not something you can choose either. sry!

Hope the ripped skin on you face has healed.
I had to use chicken wire and a staple gun to get my face back on.

3 of 5 Works with Kreidler MP... Sorta November 7, 2017
taco eater : Doug Wilhelm from Gladstone, MO United States  
I bought this for my Kreidler MP-19 (MP-9 is same motor). In order to use this, I had to do the following:

shave material from crankcase mounting area (mounting holes don't line up perfectly), reduce mounting plate thickness, and use two washers under the nut that keeps the flywheel on.

Stock motor with 15mm Bing and Proma exhaust, and I noticed no significant power gains after installing this part. Will play with timing more if I find time.

1 of 5 May work for others, but didn't for me October 16, 2017
taco eater : Anonymous Person from Redwood City, CA United States  
For credibility I'll put it out there that I am a full time motorcycle technician at a Honda dealership in California and I used to design electric test fixtures for major tech companies in the bay area.

I mounted this system on my 1987 Honda CR250R and I spent 8 hours bruising the shit out of my foot because it wouldn't start.

Inspected with my ohm meter and nothing was wrong.

Swapped the Honda ignition back and 2 kick start.

I measured the  piston position with the pickup coil lined to the magnet, notated the crank and piston position with oem ignition, then set the HPI system to be exactly where the Honda system is timed. STILL no start.

Decided to take a video comparing stock vs hpi and hpi spark is incredibly weak. You can watch the video here.. https://youtu.be/lRE4VRzHn0A

If you have something that is under 100cc this system probably works great, but for big boy bikes this system is a no go.

4 of 5 Great! But comes with Problems July 11, 2017
taco eater : Andy from Detroit, MI  
I've bought 2 of these and they are great but come with problems.

First let's hit the goods. Once set up this ignition is perfect! Noticeably more power and smoother across the entire powerband. I've had so much trouble with points wanting to stuffer and pop at high RPMs and this will fix all of those problems.

On the other hand the first ignition I bought worked for half a block and the CDI shit out. Treats was totally great to me and got me a new one with next day shipping! Cool no problem.

The second one I got had the blue and white wires on the plug flipped and the flywheel timing mark exactly 90 degrees to the right of where it was supposed to be (thanks timing light!) once I figured that out it was perfect.

Great ignition but maybe the quality control should step up their game. Overall, this is all I run now.

5 of 5 Serious ignition system May 10, 2017
taco eater : Jared Diaz from Laguna Niguel, CA United States  
This mini rotor cdI setup greatly improves throttle response and torque with the advantage of a timing curve that maximizes performance across the powerband. I was shocked at how snappy my throttle is and my low end torque really woke up with this ignition system. A+
