I have tried to put it in gear and get it to rotate but it wont budge. I took the small cover off the front of the starter and the side cover on the engine and tried to turn the crankshaft with a wrench and a socket/ ratchet and it wont move at all. The reason I am asking if I am missing something other than just the obvious that the trans or eng is junk is because it did this one time before and then it broke free like nothing was wrong and ran flawless for months until now.

Hello, Im new to the site but I have been reading the forums and like the input so I wanted to ask everyones opion of what is going on with my quad? The last time I was riding my 400 I was on the gas in 3rd or 4th gear and it started acting like something with locking up or catching in the trans, then it did and stalled the engine and the tire stopped and I slid to a stop. it did this once before but it started back and ran fine since. This time it will not crank back, wont even attempt to spin the engine. I pulled the small 3 bolt cover off the end of the starter and spun the gears, they spin fine the opposite way but when you try to spin them in the direction the starter spins the motor they wont budge......any ideas on the problem or what I may be missing?? Thanks in advance!
