Question about a BLOWN engine

[Dst4321]

A few weeks ago I installed a 100CC Big bore kit on my 50Cc this mornin as I am driving to work which is about 13 miles from where in I live iit started running really bad, smoking, dripping oil like crazy, lost all power. Could barley do 30., then I realized there was completey no oil when I stopped. .l got a quart of oil at gas station, filled it up, then continued to work whic h was just a couple miles away.bought some oil resistant gasket glue, resealed the head and valve cover. The. Did an oil change and the little pin that holds the piston on came out of my drain plug. I knew that was a bad sign. And the oil that came out was dirty and black,.it looked like it had 3k miles and it was the oil I just put in earlier.I put fresh oil in, and cross my fingers and hope I would get back home to strip my moped apart and figure out whats wrong with it Buy whatever I need it to fix itBut that didn't happen. 2 miles down the road it shuts off and I just knew the engine just blew. Would replacing the bore kit fix this promlem

Hopefully. If the lower end or cam drive didn't get hurt you might be in luck.
