maybe.. Im just happy to be able to go more than a mile without overheating now .. Turns out, if you mix in a few quality YAMAHA parts with Hisun, and modify a few more, you get a decent machine. Mine is running well now.. Just basic maintenance required ... and I use it every weekend at Whiskey Bay ... BUT I wont ever buy another Massimo... Next time it will be HONDA. I have 4 Honda ATVs... they are indestructible..
