Hi. Lately I hear a strange sound in the engine from my TTR250, it is a model from 2005 with over 30000km. One friend (a mechanic) said how it was probable the timing chain but I am not sure. I will try later put the sound here. Mostly I hear it more when the engine starts and it is not specially hot.
If the timing chain is loosing tension, what can I do? or what would you do in a TTR?
