TUNED NINJA
 

I read some good reviews about the stock ninja but not anything bout the tuned version with white head. Has anyone seen or ran this motor? IF so what do you think of it Power lowend topend tune etc? any feed back would be really helpful.

I have always ran the stock ninja and loved the motor. I bought a tuned version and the first week the top fin on the magnesium head broke of and about the 3rd week a chunk of bearing broke off on the inner bearing and trashed the motor. Nothing like a 550.00 paper weight.There was not 200.00 worth of more power in the tuned version. Stick with the stock one.

one of our club members ova here got one and ran like youed exspect it to run(but i matched him with my werks) for three meets then his bearings went

i also know of a good racer who lost his ninja tuned...dont think it lasted over 2 months

This one sounds a bit more like the mission impossible motor. Works for a short time, then self-destructs!:flaming:

wow I guess I need to just stick with the stock version and get two for that price on one tuned.
