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!

5 of 5 works great! August 25, 2021
taco eater : Troll from IL United States  
man i had nothing but problems when my buddy set this up-- then i hit up Treats and they set me right!

1) red locktite on the inside of the flywheel
2) blue locktite on the nut
3) you should have one of these (or similar)-- anything else is a PITA/impossible- https://www.treatland.tv/buzzetti-micrometer-p/buzzetti-ignition-micrometer.htm
4) have a piston stop to really get it cranked on after
5) https://www.youtube.com/watch?v=mH9IVF1RMVQ is good but the curve is misunderstood in the video-- the HPI doesn't advance it, it retards the curve as RPMs go up in order to keep the engine cooler... so you can run it more aggressively.

on the burning out issue:
1) the electrical components get hot, you shouldn't be stuffing them under the frame (we made a mount for outside
2) keep it dry

those two things seem to be the two biggest issues with it.

Hot spark, and i can run 12v AC/DC LEDs from a boat now! hot diggity i can see down the road at night!

I'll update if blows up

5 of 5 Best Ignition EVER! February 1, 2021
taco eater : Maize from Saint Paul, MN United States  
I use this ignition on all my bikes. They fun faster and cooler! The flywheel does NOT have a woodruff key so you gotta know how to set the timing. I made a tutorial if you get stuck. https://tinyurl.com/y5d8dxm7

1 of 5 Serious ignition system November 17, 2020
taco eater : Jared Diaz from Laguna Niguel, CA United States  
Update: The coil took a crap on me after 100 miles or so.  Trying to get a new one under warranty was next to impossible due to where these are made.  I ended up going back to stock and still have my junked hpi in a box.  Sure would be nice to just get a new coil but whatev.

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+

1 of 5 Awesome for 30 minutes October 22, 2020
taco eater : Michael Kuriger from Santa Clarita, CA United States  
Great performance, 60+ mph and 350 degree temps.  But it only lasted 30 minutes or so before it failed.  Maybe I got a dud?

5 of 5 Awesome. October 12, 2020
taco eater : Quattro Audi from KENSINGTON, CT United States  
Very strong system. Can run 12v LEDs now. Have it on a 65cc metrakit/phbg/mlm cali setup and it rips. Would buy for all my bikes but I'm trying the powerdynamo next.
