Tick tick clunk!

[Goose51683]

I've read many of the ticking posts of here and unfortunately none of them go to the extent my bike is at.

I had the ticking and a quick search led me to believe the issue was the valves, which was not an immediate concern, or wrong type of gas, and again not an overly immediate issue. So for the rest of the week I drove the bike to work as it is my only transportation at the moment. Well, tonight I had planned on changing the filter and the oil but after about 30 mins of riding how I heard what I guess is best described as a pop, or more like what you hear on the movies when a grenade is thrown down a foxhole. Anyways, the bike dies and I end up on the side of the road. The first attempt to restart actually had the motor turning, not firing but at least turning. The second attempt and all subsequent starts came up with nothing but a clunk. Not a click, but a solid metallic clunk.

Where do I even start. I noticed that the oil was very low. I know I checked the oil level not a week ago. So A, where did the oil go and B, am I totally boned and the engine is locked up.

My plan was to remove the starter and see if anything would turn by hand. If not i will start disassembling the entire motor and going from there I guess.

Anyone have any advice at this point?
