Went riding today on my 09 M8 HCR. I rode it for a while and realized I didn't have my bars up so I raised them and then my sled wouldn't start. We pulled & pulled and nothing but it was getting spark. Then we decided to fiddle with the throttle a little and it started and run but when I was playing in the trees & on & off throttle it would almost die sometimes. I think it's in the throttle sensor. When I got home I moved the bars up & down & now it won't start again.What do I do? Does anyone have experience with this?
