I think I have simple goals with respect to this, and hoping someone with experience can wisely advise me. My Goal: If I can't fix it, I want to at least know as much about it as not to get screwed by the local bike shop. So excuse the length of this post - hopefully I can put enough detail so that someone will know pretty much what is going on. '04 CRF250X - very modded by the guy previous to me..... Since I've had it - maintained it religously - all fluids probably changed too often. Never ridden hard, since I've had it. (Yeah, I know. The last guy probably redlined it dry and only ran pancake syrup in it....) I was riding the bike and it just stalled out - sort of like running out of gas or a fouled plug. Tried to start it - couldn't - seemed like one of the two, or maybe the dreaded valve issue. Pushed back to the truck, like 20 min later started up fine - 1 kick, no issue. Shut it off with kill switch. Started about 5 min later - and it stalled after a few seconds. Started again, stalled again. Then tried to start again - but kick start would not budge. Didn't force it. (All starts are with kick.) Every time it stalled - nothing noteworthy in sounds or behavior. All fluids were fine - proper levels, fresh, etc. Pulled valve cover off - put bike in gear and gently bumped it fwd/bkwds - watched the cam chain move slowly. After a few bumps, it moved much easier, then I was able to move kick start by hand. Kicked slowly (with my hand) over several times - maybe 3 or 4. Then it locked up again. Now - no movement. Drained tranny oil - looks great. Drained coolant - same. Drained engine oil.....well if I was panning for gold I'd be in business. There are a lot of flat brass shavings/chips - like glitter. All the shavings seem to be brass - nothing silver in color, as far as my aging eyes can see or my worn fingers can detect. Same issue on the filter - quite a bit of flat shavings. Last bit of detail. I can shift through gears no problem - but when I pull in clutch, it doesn't seem to do anything. As in - the wheel is still locked up. It obviously should release it and let the wheel spin free. If I pull the clutch in, and bump it back and forth - it eventually works and I can then move the wheel as it normally would. I pulled the clutch cover on right side and the clutch plate moves in/out with the clutch lever - but that is as far as I went. Please! I'm hoping for a bit of guidance, advice, and possibly a good starting point. I've turned a lot of wrenches in my life - more on cars, and not on bikes for a few years. I'll do as much as I reasonably can taking into account financial costs v. time. Thanks in advance, especially if you've taken the time to read the whole post.
