I just rebuilt my raptor 660 bottom and top everything, wiseco 11:1 piston hot rods crank, has about an hour on it now, and was out really riding it today........ I stalled it, and started it back up, and it knocked pretty bad for a second right after start up, motor was hot, about 180*. It did it just for a second and went away, and runs fine, no noises other wise.
Is this something to worry about? Never did that before, except for the bad knock it made before cause old crank was loose.
Should I be worried about this, or is it something that is normal on hot start?
