Salam,guys im having a honda CD 70 2008 model it has done 75000km and today it has started a very high noise of connecting rod and another sound which i cant recognize but it is like bearing...sound is very annoying or disturbing but one thing is that bike is running fine there is no smoke in exaust and no noise of timing chain.........

Do i really need a engine overhaulin or need to change some parts ?
and if i need a engine overhaulin or what are the parts which i need to changed for my bike engine and
i also need info about that how much a cd 70 could do with its original engine my bike had done 75000km is it enough or not
