take the cdi box off and try cranking the scooter youll notice that it still sounds like the coil is bad then wait till night time plug the cdi back up then watch the coil if it throws a spark its not your cdi it might be your spark plug but if you see no spark then its most likley your cdi box or coil thats teh best way to know if your scooter is cdi enabled or needs a coil theres a big defrence when it comes to price of these devices though.
any one know aboat 50cc Honda sfx scooters on cdi ignition box
the rev limiter is built into the CDI, you can get a CDI without the limiter on ebay.
what wire do i cut on a cdi box on a schwinn scooter 49.5cc
CDI box
replace the stock CDI with a performance (orange or blue) CDI, make sure you get the right one, some are AC and some are DC.
on 5occ - 150cc gy6 qmb or qmj engines the rev limiter is part of the cdi programming.
Because it is limited by the CDI. The CDI is a small black box with 4 -6 wires running to it depending on the model. If you have an Asian made model chances are its a 6 wire. Find the CDI and look for a pink wire. Cut it a use electrical tape to cover the ends. That's all. Also, search for derestricting 50cc scooters.
Check ur spark plug and if none of them are firing the its ur cdi box
first check your spark plug then test your ignition coil if these are good then it is probably the cdi but there is no way to test a cdi box.
Go to a scooter store or go online, they sell cdi units that have a potentiometer that will allow you to adjust the timing, just need a timing light and remove the left engine plastics to see the timing marks
in the CDI (Capacitor Discharge Ignition) box, you can get an aftermarket CDI cheap on ebay, if yours has 6 wires going into it then it is AC fired, 5 wires is DC fired.
Beside a racing cdi box, the only thing you can do is use a offset key on the flywheel. Just a thought, one could elongate the bolt holes on the stater so it can rotate slighty. Warning playing with timing can have serious problems with engine parts.
