Yesterday I bought a used hypermotard 796 2012, with just 3800 miles from a dealer, first everything seemed good but when I rode it to my home(15 miles) it stared to over heat and the engine oil light got on(red light). The dealer told me that it only needed a tune up after about 6000 miles. But I don't know what to do. Very worried. Really appreciate if anyone has anything for me? Please. And the engine also felt like it was about to seize. Don't know much about the bike.
