I just bought a DF250RTC about a month ago and had it out for a ride with speeds up to 60MPH, when I got home the bike was dripping oil and I cant figure out from where. I took off the farings and noticed a black hose on top of the engine connected to a black resevoir with another black hose coming off the top of it and it is connected to nothing. Is this suppose to be connected to something and what is it? Has anyone else had issues with the bike leaking oil after a long ride.

Also wanted to know if anyone has had issues with the speedometer being way off? Speedometer was reading 70 and passed a radar check on side of road and clocked me at 45. Had speedometer up to 90 at one point and was still being passed by cars in a 55MPH zone.
