Hello I had built in a new engine days ago because my old engine was botched. Well with the installation I apparently now also failed miserably 2 Yamaha books and step by step everything checked off and marked. Engine has 200km down So to the problem new engine started running without problems after 50kms started with cooling water problems Moto control light did not light up. probably means that it also didn’t get too hot. But! The Maschiene has up in the cooler instead of 1l nu r 500-600ml of coolant fit in. Before emptied on the screw on the cylinder so should be as good as nothing in it. well was full once turned on and let run until all bubbles come up up well maybe still 50 ml refilled closed up. The compensation tank filled up to the prescribed 250ml between Min-Max so few round driven not far about 15-25 km. started to shoot me the coolant from the cooling system into the compensation tank de r then in the ride passed noticeably by drops on the disguise and puddle small ones. Then the Maschiene Schleichend started to get start problems as soon as she was on but she ran without problems then went before after a ride briefly into the bank to withdraw money afterwards I had to take about 2-5 min organs until she started. See video (home after 10 min standing time so still warm) Do not need any stupid comments either I know I’ve shit something. e New engine 800 for the air. Sparkling plug Rzufern was wet smelled of gasoline. But I have no idea about despair. Machine: Yamaha YZF-R125 Re06 bj2011 New replacement engine.
