Ok, I'm new to this forum. First post and all. But I think I just royally messed up my bike. What was going to be a quick fix I think just turned into a major issue. So here's the breakdown of events. I bought this bike a month back, knowing the previous, previous owner did a top end rebuild on it. It was a pain to get started if it wasn't warm, and stalled out constantly when i would ride it. Whether it be my lack of experience on a 450 or not. I've been riding 250s for a Long time now and they've never been an issue, but having a 4 speed, I think is what made the stalling an issue for me. Regardless, I opened the valve cover to see if the timing was off, and it was. So lil ole me decided to adjust it. I went through the book and adjusted everything to how it was supposed to be, put it all back together, and THEN decided to turn the crank to see if TDC was correct. So I rotated it. It stopped and wouldn't rotate anymore after maybe a half a turn. That got me pretty irritated as it was just fine before I messed with it. So I took off the valve cover again, and pulled the cams out. And that's my problem. I now have both cams out, and it's not at Top Dead Center. I have No idea where the cams where before, and I think the crank wouldn't rotate due to me not knowing that there were (piston like) rings in the cam, and one fell out jamming it up. I also noticed a little bit of metal shavings when I pulled out the (intake?) cam. Not sure what that cams called. The other one from exhaust cam. I'm in dire need of help as to where to go from here. I have both cams out and everything covered. But what do I do?? I'd appreciate any response. I'm about to just take it too a shop and have them fix it up. Thanks! Oh and by the way, I found my spark plug was completely fouled when I pulled it out for the first time after I got the bike. It looked to have fuel or oil on it and was pretty dark. Im assuming it was running way too rich. Thanks again.
