I use regular 87 gas, during the riding season, every two or three tanks Ill add a dash of seafoam. Winter time, my girl does not ride at all, so then I add sta-bil for the winter in all our machines. Mike

I just bought my son a 2018 Ds70. First off it ran fine at dealer and when I got it home I couldn't get it to run without the choke. I took it back and the tech took the carb off and found the low speed jet was completely clogged. He said he bored it one size over stock. Now it seems like Im chasing my tail with it. The idle is erratic and the plug is white, which Im assuming is lean. It takes at least 10-15 minutes to get warmed up which I know is not right. He is ordering me a new carb and Im having him put a DS90 throttle cable on when I take it for the carb and 10 hr service. Has anyone had any experience with these little atv's? If so please give me some pointers on what to .
