I need to know how I can re wire a diffent cdi I box to a sq 125 kt cheetah go kart I can not find any were to buy a new 1 as it it a chinese import I did not relies that until I blow the cdi so any 1 out...


It\'s always a pain to deal with the Chinese imports due to parts support, but there is a silver lining. The parts are usually interchangeable with many other of their clones. Looking on Ebay there is a good number of CDIs. See which one would be most applicable given your connections. There are entire kits such as this one:

71543030962?pt=Motors_ATV_Parts_Accessories&hash=item27f0c2ecb2&vxp=mtr">http://www.ebay.com/itm/CDI-Relay-Ignition-Coil-Rectifiter-Kit-for-Chinese-110cc-125cc-ATV-GO-KART-Buggy-/171543030962?pt=Motors_ATV_Parts_Accessories&hash=item27f0c2ecb2&vxp=mtr



They are all relatively inexpensive, the trick is to figure out your diagram and match it up. I even some some higher-end looking CDI boxes for engines that may be like yours.

How to bye pass a scooter cdi box?


You can't, unless you want to push your scooter everywhere. The CDI box stores an electric charge that is sent to the coil to create a spark that makes the engine run. No CDI, no spark at the plug.

Generic Chinese CDI's sell for less than $10 and are perfect, if unreliable, copies of Honda CDI's. Just get the same kind of connector as on your CDI.

I have a 1985 honda shadow vt500c, and like many others before me, im in need of a cdi box, or a fix to a broken cdi box, the used ones on line are a bit pricey for my wallet.


Unfortunately, the ONLY thing you can do is replace the cdi box....what REALLY sucks is that those cdi boxes were only used by Honda for 2 years...85 & 86...all the other years/bikes had MUCH cheaper units on them...And DO NOT, I repeat DO NOT waste your time on a USED part that is 30 years old!!! There is NO WAY to test a cdi box!!! Bite the bullet & buy a NEW one if you want to fix it & forget it.....there are new ones available online from a company in the UK for about $259.00 I speak from personal experience with this EXACT issue & once you replace the cdi box, that bike will run (providing everything else is good)

Best of luck!

92 virago 750. Front cylinder runs intermittently. Coil is good. I cleaned carbs. Suspect CDI. Seems to run fine until it warms up. I recently put new Voltage Regulator in. Stator is not shorted. and...


You have to test all the electronics on the bike to figure out if you have a bad CDI box. A CDI box can test good and still be bad. Your problem sounds more like a bad spark plug cap. Unscrew the cap from the end of the wire and take an OHM reading on the cap. If it is higher or lower than 5000 OHMs replace the cap . A plug cap from NGK runs about $5. Replace them both for about $10 it should take care of the problem.

What causes cdi box to fail? the big red ran fine,but when trying to resart it the next day it will not fire. Also how do I know if it is truely the cdi box?


many things can cause a cdi box to fail they are hard to diagnose. but as far as testing goes u can use an multimeter to test ur resistence in the stator and coil if they test good its the cdi. or even a bad ground can cause it to loose fire.
