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!

these now come with two leads along with the cdi harness off the stator. the yellow with with the ring terminal is grounded and the other yellow wire with a female spade connector goes to lights!

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!

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+

perfect for derbi February 22, 2016
taco eater : Ryan Nash from New Orleans, LA United States  
*EDITED 2/22/16*

I've used this on Puch, Derbi and Minarelli V1.  Pretty much the only ignition I will use.  This particular one also bolts on to the Derbi 4V motor (4 speed shifter).  Bolts right on, no modifications.  It also bolts right up to PR and PP cases.

Original review:

bolts right on to derbi flat reed cases, and probably pyramid reed and piston port.

HPI says 2-4mm.  At 4mm it ripped my skin off my face but quickly got heat soaked.  At 3mm it had violent take off but still was a little too hot to handle (400+).  I settled at 2.25mm with max temps @ 380deg.

Just get it, stop reading the reviews.  BUY ME.  You won't be sorry.

Finicky but amazing September 11, 2015
taco eater : Anonymous Person from Derry, NH  
The reason it tells you to time it anywhere between 2-4mm btdc is because the actual firing marks vary A LOT. Mine was around 20 degrees advanced from the mark on the stator causing me to run backwards until I used a timing light.

Also be sure you dont take too much weight off your crank!

This is however no reason not to get it, its got amazing throttle response, bright lights, and ease of operation once you learn to handle its amazingness.

Edit: the stator can shit the bed randomly. You may have it work for 2 months or maybe 2 years who knows. I had it installed by the guys at lucky 2 strokes the first time and followed the same method every time (not much method to it) so I know it was right. Then ran it for 3 months then gonzo. it really sucks that this can happen to a $300 CDI that one might expect to be reliable

Awesome RPM's September 23, 2014
taco eater : jbruzer from Lancaster, PA United States  
Just keeps on whining baby!! YEAHhh!!
(A55 LX- This product works best with a stuffed crank, tighter clutch springs and clutch, and around 2.5mm piston adjustment from TOP on head of your 70 or 80cc engine)

I slapped on a 70cc Airsal kit, a biturbbb and a 19mm PHBG race clone, and boy this just couldn't be any better Ill tell ya! helluva machine
oh and a uni air filter
44-46mph half throttle.   47 48  49   50 is full throttle with increasing rpms.
are my lights brighter as well? yessir-dippity
carefull itll start spitting and spattering and heating up if it isnt timed right

Best spark July 31, 2013
taco eater : Creature Ed from San Francisco, CA United States  
Solid Spark all the time even at high rpms. Never worry about points again. If you trying to build the fastest bike you can the mini rotor will help your crank spin faster! DUH. Don't be a dummy get this hpi.
