i now close the chapter on my ninja.

mine was the last of 3 that started last season in our club, to die.

2 rods and a piston cracking in half did ours in.

i have had sirios, novas, x12, and all have been abused at times. and they are all still running with NO parts changed.

i replaced the bearings in the ninja, and was due to replace the rod TODAY!, and it broke yesterday.

Good motors while they last. i thought mine would last.

Hope OS makes them better, what am i saying OS will make them better. Good luck
