so we have an Apex 90 2010, very very low hours, started it the other day after its been sitting for a month, rode around the block just fine. Went out to the track and could not get it started no matter what!!!! So far ive replaced the spark plug, pulled apart and cleaned the carb but still nothing! I have a feeling I have no spark, how can I test the coil, cdi or stator????
any help or advice is much appreciated!!! Im starting to really hate this quad!!!!

well pull the plug out and kick it over to make sure you have spark or not. if not clean up the pick up on the outside of the flywheel, ive heard of those getting dirty and causing no spark. my apex just had a stator go out but luckily i had a scrambler 50 that uses all the same ignition parts to swap parts around.

Test for Spark... First remove plug and put it on the frame and see if it sparks while turning it over. If not remove plug and boot and then put plug wire to the frame and see if it sparks.. If not then it's either the coil, cdi or stator. It can also be bad wires or a ground. I have all parts you need to just replace all and call it good. New stator, coil and cdi for $125 Shipped. I can also send you some more info on testing things, but it's some times a pain and just better to replace all and ride hard... Let me know thanks hope it helps..
