    Question 03 YZ250f

    It does fill it up after running but it doesn't stay there long. somethings wrong. My other 03 yzf250 doesn't do that. when I change the oil all kinds of oil comes from the frame bolt on one bike but none from this one it all comes from the motor bolt

    Question 03 YZ250f

    I had the motor out and rebuilt and now after you run the bike and check the oil it reads good but after a little while I check it again and then it has ran back into the motor. this isn't right it should stay in the frame it does on my other bike my question is: the oil lines from the frame to the motor were off, could there have been a ball bearing in one of the lines to slow the oil down or a chuck valve that might of gone bad? need help

    Question:What rim will fit a o5 crf250

    I My friend wants to get a complete rear wheel set up to put a paddle Does any body know what year cr125 will fit, I'm sure the crf250 04 will fit. I see some adds saying that a 450 rim will fit but that seems weird because it takes a bigger tire, what else will fit?

    Crank rod question

    I broke the rod in my 03 yzf250 and it messed up the crank pretty bad also. I wanted to get a hot rod crank kit but it seems they don't have it. Is there a kit out there and who has it. Thanks

    I broke the rod in my 03 yz250f and I was going to get a hot rod kit for it, but I found that they don't make it for that bike. Who does make a complete crankshaft and rod and how can I get a hold of them. Thanks
