Engine check light

99 Views 0 Replies 1 Participant Last post by  Pistocchi Kevin
I recently bought a yzf r125 from 2009. Every time I go above 6000-7000 rpm the engine light comes on. A week ago it was just fine. And once the engine is warm and you let it run in neutral, it goes from 2000-2500 rpm and switzches back constantly. Can somebody help me?
