so i recently bought a 1997 RM250. i was riding it with a few friends and because im still a rookie on bikes i fell over going around a birm. when i fell i picked the bike back up put it in nutral and went to kick it...nothing.. it didnt even budge. the bike was running strong, new fuel, new plugs, i took a look and the piston is free and moves fine, but has a little wiggleing room. i can turn it over with a wrench... so do you think this is my crank bearings or could it be something else that has a bigger problem. i looked at the kickstarter as well and its installed correctly but when you try and kick it, it will not budge, rmove the assemly and all that then you can crank the pistion up and down but its pretty difficult and i belive it should flow smoothly.. any ideas?
