just put a new crank in my 05 yz 250.. (i had to remove the gears when i split the case to do so). now i've put everything back in, in what i was certain was the correct order and place. when i shift the bike it'll go from first to neutral to second then what feels like neutral again for both 3rd and 4th then 5th. also then clutch seems to only engage when it wants. Any suggestions?
