Today while out on the track i seized my crank but for months now ive noticed that the bottom of the engine gets real hot. Hotter than you could touch with your hand. Is this normal for this model or have i got some sort of issue here? Once i stripped it down i managed to free the crank pretty easily probably because it had cooled but i can still feel a sticky spot when turning it so it needs a new rod. Im just wondering if the excess heat could have caused this or did the crank just decide to call it a day.
