I just got a 2001 yz250 and have a few questions. First what do you think the top speed is on this bike. The other question is about the vent hose that is connected to a small 90 degree elbow on the cylinder head I think is is in relation to the exaust valve. But I was wondering if oil is supposed to be dripping out of this hose, it looks like the oil that drips out of the exaust pipe.
