Tried to start my bike yesterday and got this very loud clackity clack noise comming from my motor . It would get louder and faster as I would give it power (not too much of course) but then it would go away for a few seconds then come back as if there is a ball bearing bouncing around in there. It's not a random sound either, it's tied to rpm but slower. I got out a stethescope that I just happened to by friday to see if I could hear anything out of the ordinary but hell I can't tell what I'm listening to! I pulled the valve cover and S.G. cover off and turned the crankn to see if I could duplicate it to some degree. No luck there. I will say this though, the last time I had my cover off and turned the crank it seemed a lot tighter than it is now. Also, shouldn't the valve springs be tight in thier seats? I'm getting quite a bit ov movement out of them, there's no up and down play but I can twist them pretty easily. Any thoughts?
