I just recently bought an 01 blaster and the kickstart does nothing. sometimes it will turn engine over but mostly dont. i took the side cover off the engine and all the gears look fine. i tried putting it back it worked two or three kicks then did the same thing. so i looked at the idler gear i guess it is what it is called and the engine itself has a crack above it. will that cause this problem. i am new to this and off to a bad start
