A few weeks ago my 3up spark overturned and it was uprighted within 20 seconds. About an hour later it overturned again and was uprighted in about 10 second. Everything runs well but the seat feels like it’s water logged. The reason I think that is it weighs twice as much as my 2up spark seat. I don’t remember it weighing much more than the 2up seat. I have had it airing out in warm weather both indoor and outdoor propped up so air can circulate around it. Has anyone had the same issue and if so, how did you resolve it? Or maybe the 3up is way heavier. Thanks
