Ive got an 05 ren x 800 and am noticing a slight hiccup when I first open the throttle and when I back off the throttle. The motor has about 4 hours on it. I notice the condition most when I'm comming up to a stop. This is my first series 3 engine. I seems something is not quite right. I also notice the sled engages very hard. It goes from stop to hard acceleration. The sled is not easy to manage in tight quarters ( crowded parking lot ). Are these conditions normal? Thanks for any info.
