I just picked up a non-running 2013 ninja 650 thinking it was just electrical issues but when I was trying to manually turn the engine over with the timing bolt on the right side. I found a loose gear and missing bolt head that goes into the crankshaft… any suggestions on how I can replace the timing rotor bolt. I’m thinking of getting a bolt extractor and/or taking the engine apart… is this engine a lost cause or should I put more time into this to see if this is the only problem. I was going to take off the stator and crank the engine from the left side and see how locked the engine is or if I should test compression and timing
