I just bought a 2007 yz 250 2t. The bike is very clean with very low hours. I just installed a fmf gnarly pipe and titanium 2 silencer. The bike seems to run great but I'm getting some spooge from the silencer . I still have the stock jets in it. 178m, 50p, 2nd clip on needle. I have a boyesen rad cage coming and plan to install soon. I'm a new to two strokes and have been spoiled with fuel injection. Two strokes are so much more fun. I am in Louisiana so I'm at sea level, 75 degrees f. Should I got up on main jet or down? Up on pilot or down? Up on clip position or down?. I'm also getting some oil coming from powervalve when parked. Not a lot just a couple drops.
