Hey Guys, Great forum y'all have here! I just traded my ATV for a 1999 kx 250 and the guy showed me all the paper work where he just had the whole entire motor rebuilt, spent over 600$ So today i was riding in 5th gear wot for about 20 seconds and it started bogging down loosing power, then it just completely locked up. I checked the oil and to my findings its Milky looking oil, And then when i tear down the head i find Plastic shaving all over everything. The shaving came from the crank rod assembly. What happened that it tore up?
