i got a 4-tec in trade and i have a ninja .12 but it will not fit. crankshafts are different. it looks like the threads are to long and the bell will not fit. i know with the .18tz in a revo people grind the first few threads down. i would like to not do this. i know there has to be a way. anyone done this or have any ideas? thanks
