OK, This is a tale of many mood swings! I will preface it with me trading my 2005 YZ250 2-stroke, so I could get my son a 2007 250f. I didn't want to do it, but I did it to make him happy. He had been riding it one day for probably 2 hours on and off. I told him it was my turn. I made it 3/4 of a lap and the bike went from wide open to a pop and then rolled to a stop. Wouldn't start. After troubleshooting for days!, turns out it was a bad stator. Replaced it, put is all back together, my son can't get it started. I go over, 3 kicks it starts. Next day, he can't start it again, but now I can't either. I try again later that night, 1st kick! Next day, can't get it going again. I call Eric Gorr and he gives me 3-4 things to check, which I already knew about, but was hoping he would have some secret that I didn't know about. First thing, take the flywheel off, bingo! Between the flywheel and the little black knob it transfers the electricity to, a circlip was stuck! SWEET.....OH Sh!t, maybe not. Where did it come from? I start digging around on the clutch side....then OK, duma$$ me accidentally dropped the ball bearing from the inner clutch into the motor. Any ideas on getting it out? I have the right side case off and the complete clutch off. Here is what I've tried: - searching around with flashlight and prodding with a small magnet - flushing the motor with gas (with the side case apart). I am not sure if putting the case back together and putting more gas in there will help free it up. - We tried laying it on both sides and jarring it a bit to get it loose from wherever it is. - shifted the bike through the gears thinking it may be stuck in the tranny somewhere. - pulled the flywheel and stator in case it somehow got up front. The only two things I can think of are putting the cases back together and putting more gas in to slosh around and see if it gets to where I can see it. The other, tip the bike upside down, then to the sprocket side to get it to roll down to the filter on the bottom or the motor. Any other ideas - besides splitting the cases?
