The mechanic also replaced the piston springs, oil, oil filter, antifreeze and checked valve clearence. For about 1000 km I rode it soft, then I replaced the oil and oil filter. At 65000 km the bike felt like new. Now (66500 km)
I hear a strange metallic noise from the engine when braking, like two metal sheets hitting each other. I can't figure out what it is, I have to get the bike back to the dealer...

I just got back form the dealer..There's no problem at all with the engine. He said the engine sounds and is healthy. This sound might be from the brake pads. He suggest to clean the brake pads, disk and caliper. That's all....relief!...
