So I bought my bike and took it straight to the track. I just checked the oil lubed the chain and air filter, and headed out bike was fine all day well atleast till the end when I thought it sounded a little funny. So I loaded it up and went home got to the house unloaded it to take a test ride to see if I could figure out what was wrong with it fired it up let it idle for a minute went to take off and boom stopped running.... Went to kick it and kicker wouldn't move so I put it in gear rolled it backs freed and up and pushed it into my garage let it cool down and it fired right back up fine but the coolant was low which my dumb self didn't check what should I do should I rebuild it will it be fine I'm kinda lost on what to do plz help!!!!
