I live in Philippines
I went to our province using my bike, from manila to pangasinan, almost 180km distance, running for almost 5 hours with atleast 2 stop overs... After staying for 2 days in province, i went back home in manila.
Got home at 4:30 pm from province. 6:30pm I went to church for practice. As i use my bike, i notice some weird noises in my engine. Sounds like rocks were moving inside whenever i release the gas as i slow down. What is it? Is it a big deal? I never missed changing my engine oil every 1500km milage.
It was only my second time traveling that far. I usually use it when going to work and school.

If it had a 2 stroke engine it would be close to needing a top end rebuild.
With a 4 stroke engine, it might only need
a valve adjustment (full tune-up)

You probably need rod bearing replacement. Well, it means rebuilding the engine. Please study this animation.

Try checking if your drive chain is too loose. I think the same thing happened to me before. Shouldn't be so hard to fix if it was just the chain.
