hi all hoping someone can help had this quad for 4 years it was running perfect then key ignition was pulled out was left lying in shed for bout 2years, started on trying to get it going again.i bought new battery for it clean the carb and bought new key ignition..the start button on the handle wont work but when i jump the relay with screw driver it gets spark and the starter is turning..what else could i do to try get it going again any help greatly appreciated

Are you sure all the lock-outs are set, for most quads, either the bike has to be in neutral or a brake on for the starter to work on the button. If all that is right, check the live feed from the ignition switch to starter relay, some bikes run direct to one of the thin wires on the relay, some through the start button to the relay.

thanks for reply!
quad is fully automatic the foot brake is the only lock out and i did have it pushed when trying to jump it the kil switch is also on the on position...i dont have a meter to check the live feed :( should the bike not start when its jumped from solenoid with the key igniton on the on position ? or does this indicate that it may need a new cdi or magneto??

The CDI has nothing to do with the starter circuit on these Chinese Quads. There are two separate circuits in the ignition switch, one lets battery power to the satrter, lights and horn (if fitted), the other circuit earths the CDI. If you have a spark, the ignition system is OK. Without a test lamp or meter you will struggle to find the fault. Check the fuse and wiring connectors.

ori ,sorry i don't no much about these ,the fuse is good as its a new 1, all connectors i think are good.....i have bought a meter since wondering what readings should i be getting from the different connections ect...thanks

What does it do with the plug installed?

vlittle the second video is it with the plug installed ....first video is it out showing spark

Pour some fuel in the spark plug hole.. put in the plug, attach the plug wire and crank it over.. What does it do?


It sounds very dead in the video.. I would check valve clearances nextr.

Does the brake light light up when you use the brake? If not it is the micro switch on the brake.
