hi, so yeah great, another yz426 thread started by me , but any howw, so today letting it idle more and stuff it started to make a metallic pinging once warmed up, which i would asociate with knocking,
now then i checked the oil and the oil drips like its water its so thin, i dont think ive had oil thats this thin? and i put 0w 30 synthetic in my snowmobile and its not even THAT thin!, this stuff i would say its like water maybe a bit thicker, and it is oil you can feel it has lubricating properties but its thin, i pull my dipper stick out and its all dripping off it and running off it as soon as i pull it off as if i dipped it in water,
so, can real thin oil cause this? i know my 06 yz450f when i got the motor pretty darn hot or the hotest ive ever gotten it, i was going up some real slow riding through a tough horse trail and i could hear it starting to knock or make a bit of pinging noise, probably from being so hot and oil getting much thinner i would imagine
so im just wondering if i should assume its knock and it needs a new crank/piston or could it be that its the oil which is the thinnest stuff i've ever seen?, Thanks again!
