my speedfight wont start?

I broke down yesterday and my bike wudnt start so i pulled out the sparg plug and gave it a clean and put it back in . By the time this was done the battery died so i got jump leads and got it going again then as i was going down the road i lost power and the bike bogged out could this mean i need a new battery and spark plug or need top end piston rings and new crankshaft .
