Hello everyone thanks for having me. i bought my 4 year old a used Roketa
. he said it was 50cc but it says 72s on the block. it was running great and then it just stopped getting spark. isnt there a way to by pass everything just so it will run? I am not worried about lights right now/

 

The ignition system on most quads is totally independent of the main electrical system, no amount of messing with the battery wiring system will alter it one jot, so don't. Do the tests in the "help diagnose stator" sticky at the top of the Chinese engines section.
