  1. Thanks for advice but tried that, didn't help out.. :/
  2. I checked the torque of flywheel bolt. It's ok it does'nt move to any direction. About stator plate fixing screws I checked them too, those are ok too. checked pickup coil and stator coil resistance it's ok. I really don't have a clue what could be wrong. I'll try to check once again ignition coil maybe there is the problem. i know that it isint normal to open throttle a lot when trying to start the engine, but i just wanted to show what kind of sound it is.
  3. I just tried your advice. Bike much more easily wants to start but when it does it runs only for couple seconds and then stops.. Any ideas? What about that strange throttle sound, maybe you know how to fix it? Any ideas about spark plug problem?
  4. Hello everyone, I have a problem with my SR 125 '97 custom and i can't find it whats wrong, so I really hope that you could help me. Let's begin with this video: https://www.youtube.com/watch?v=V-LMRUT7IC8 Is it normal that spark shows not cyclically? But in the beginning and end when I push engine start button. What did i checked: battery is ok, changed spark plug, spark plug gap, checked ignition coil with tester one of two methods, checked pickup coil resistance, even changed CDI unit, nothing!. I don't know maybe spark cable is bad or I checked wrongly ignition coil, pickup coil resistance, source coil resistance.. I don't have an idea how to make that bike run. The best help i think would be is SR 125 owners could say do the spark shows the same way like mine do, but i really think something is wrong with mine. Second problem, video: https://www.youtube.com/watch?v=15HlmQh1_o0 Strange sound when i accelerate while trying to start engine, actually is the same sound come out when the engine was running and i accelerated quickly, if i do that engine just immediately stop running. What I did: Firstly and till now i think this sound is because of bad mixture of air and fuel (petrol) that's might be one of the reasons cause till now i can't adjust air/fuel mixture well cause i have not a original air filter, and the stock parameters might be wrong. I'am talking about pilot screw (2 turns out or 720 degrees) cause custom air filter give more air then original so i think pilot screw should be screwed more than 2 turns out, PLEASE LET ME KNOW IF I"AM WRONG. Actually about this problem i have no idea what could be wrong i'am just guessing, maybe its mixture. And last video shows how it trying to start: https://www.youtube.com/watch?v=7jSSJE901ao So I really hope you can help me, waiting for any advice. Thanks
