We changed our oil a few weeks ago and it ran fine at first..we had a spout of cold weather and we didn't get to ride for a week or two. We got on it this weekend and started to ride and it would stick in first and second gear and eventually start to to shift normally. We went to turn around and it just died...luckily we had someone jump the battery and off we went...but it would stutter for a bit and then straighten out. We cannot for the life of us figure out what's going on. The only thing we can think of is the wiring that has to be disconnected when changing the oil maybe we didn't get one hooked back up...please help!! Also the gauges are not correct it says we're going 115 and we may be doing 30.
