ninja or OS
#5
I have been running the O.S. for over a year now, very reliable engine.
But I have recently put in a Ninja, so far it's been reliable, But -- there's a bit(ok a lot
) of a performance difference, its a lot quicker than the O.S. 
More than happy with the NINJA !!

Remember, most people are running the Ninja as a Motor and pipe combo. ie. Ninja motor and Ninja pipe... This should extract the most power from that motor. The OS TZ, when match with the correct pipe and header can run with and beat the Ninja in the proper hands. Don't get me wrong, the Ninja is a very nice motor, but so is the OS when geared correctly and matched with the correct pipe and header to take advantage of it's low and midrange power and torque...
The Ninja pulls nicely and has very good top end. Mugen has a very Nice Motor in the Ninja!!! The OS is a good motor as well, it has more power down low/midrange then the Ninja and top end can increase when setup correctly. You can't go wrong with either one. Buy the motor which best suits the track you run on...

Also remember the ninja is a relativley new motor, so any problems may not have been seen yet. alot of people will say to use it cause its new and fancy. Buy what you think is best for you not what is the latest fad.

I think you don't have a single clue to what you are talking about, don't you think 134 days is less than a year.
