squeaking??

[motophreak]

I bought a new lifan 125cc from dhz, when i got it i drained the so called oil and added in some 4 stroke mineral oil, did the valves to 0.003 and 0.004 for inlet and exhaust and bolted it to my bike. when i kick it over there's a loud squeaking/squealing noise that to comes from the engine, have no clue what it is and it doesn't sound like a metal scraping metal squeak but just would like to know.

has this happened to anyone else, or is this the norm for a new engine??
Thinking of doing my valves again but if that's not the problem i'll need some other suggestions.
And yeh i do know the lifan 125cc aren't the best engines out there but i thought it would do for now..

Thanks..:grinning-smiley-003

Squeeks a little when you first kick them over as the oil get's around the motor but should stop pretty quickly I would have thought.

awesome thanks..

If it doesn't stop pretty much straight away when you start it. Kill the motor immediately and start diagnosing potential problems.

make sure the nut that holds the clutch on is tight.

yeh when i got it i checked everything accessible like the clutch, magneto and that so its all good, i got it running well and there's no more weird noises lol..

i reckon it was just lack of oil in the barrel, and the noise was coming from your rings
