BTW, I'm new to two strokes, haven't had one since I was a kid and dad did all the work. Ok, so I've searched and not found what I'm looking for so figured I'd ask here. Recently picked up a 2000 yz250 that supposedly has a 295 or 300 big bore kit. It ran strong so I didn't fret too much over the little things. Paid $1500 and took it home. Drained the gear oil and it looked a bit odd to me. I refilled with Rotella, ran it for about 15 or so minutes out back. Drained and it looked the same. 😏 Could this be water getting into the oil? Read somewhere that it should look like this but seems odd. Any help would be appreciated!
