Hey people whats going on. Normally ride street bikes but finally fell into temptation and bought a brand new 01 yz426. Killer ride ( not my first dirt just been awhile). Anyway question: 1: rode for a 1 hr like the manuel said and changed the oil. This was probably the most funky oil I have ever seen. Is the first few oil changes always that dirty. I mean it looked like nasty. SO I was going to repeat the process again and this time go ahead and change the filter. 2. One more question how in the world do you get the frame hose off to get the screen out, I got the skid plate off and the hose clamp off and the frame oil bolt but could not get the hose off?
