I bought dismantled Predator 90 2005..It was dismantled by thieves..Now its almost ready to roll but spark is missing..starts great but no spark..ignition keys wires were cutted and lock was broken..i connected red and black together and brown & green together..it starts now but not run..What wrong? CDI Box...I bought Nasara tuning box on it but wiring is wrong for predator..Finn quad owners can not help me..

 

Clean the flywheel and stator are,this was the major problem area on the little ones. If you still have problems look here to see if they have a manual that will help.PartShark.com - Motorcycle Parts, ATV Parts, UTV Parts, PWC Parts, Powersports Apparel, Motorcycle Accessories for OEM and Aftermarket. Plus with wiring messed with,could be anything? Manual will help. OPT

 

THX for quick reply..i have predator 90 workshop manual on cd...Hmm i ahve go clean magneto and stator..It has given one time very very weak spark,,i feld it on my finger..like needletouch..but not anymore..it lost..

 

Most of the problems I had were stator related,but look on the pdf manual you have for the stator and coil resistance specs if after cleaning the stator you still don't have spark.At least this will help you start eliminating problems one step at a time. What you have to do when thieves have screwed with the wiring,plus if in doubt on the ignition switch just replace it. About $30 at Cycle Parts Warehouse. OPT

 

If you end uo needing a stator, this oneis the same except the ID od the seal is different. I used one and popped my old seal out and reused it in the new stator. The seaal just keeps grease in the crank where the injection pump drives. Or order a new seal from polaris.
Runs perfect and much cheaper.

I cleaned stator and flywheell are,Found lots off dust..But no spark. I checked volts with meter but they were very low 0-4.8volts. Ithink iits stator...my friend has extra stator from Minarelli scooter (Same motor on my Pol), i will use it to test

 

New stator...no spark...F....k...It must be wiring what is the problem...

 

Just because the engine is the same doesn't mean the electrical components are! I've had several people try to use different parts from other machines and a lot of times they wont work. Best to use an oem stator if you're sure it's the problem or try this place and see if they can help.

Its 100% same..wiringcolrs.. etc...And it gave right volts when motor cranked..

OPT...why this system needs that cdi box..would it work with out it..

 

Cdi module takes the place of the old points and condenser. It times the small spark signal it gets from the stator then sends it to the ignition coil where it's amplified. Pm LynnEdwards in the Chinese section as he is the top dog in electronics on the little Chinese/Korean atvs. OPT
