pour a gallon of gasoline on it... then toss a match on it.

That's about as good as it is going to run

LOL Im just sooo frustrated, I love Ninja's and Ive run a whole bunch of em!! My next step is to completely break this engine and carb down and make sure it was assembled right. If that does not work then I dont know what? If anyone does have the proper needle settings that would be a great help

Thanks to everyone that has chimed in.

I found that my 2 ninjas were around 4 out on the top end and 2 1/2 to 3 out on the bottom. Try that, Jason did you put the nova rossi #7 in like I did. It really worked for me and also for everyone else that I told the tip to as well

Ok I have torn the engine down, it looks fine. I have gone through the carb, it's getting fuel, this engine will fire for a few seconds about every 3 hours!!!! It seems to have a mind of it's own and I no longer have the patience. I not gonna pay top dollar and spend three days just trying to get an engine started. I will see if I can get it replaced.

Thanks to all who have contributed input

Jason

take one of the carbs off of your old ninja to see if it makes a difference and then you can either pin point it as the problem or rule it out...

I thought of that, but I dont have any ninja 12 carbs.. only 21. I do however have a bunch of mt12 carbs, but I dont think those will fit properly.

Any current Nova, Sirio or Picco .12 carb should fit.... Try one of those that you or a friend may have that is tuned correctly and put it in... You should know then if it's the motor or your Ninja carb. Good luck.

Oh my god it lives!!!!

Here we go...I took the carb apart, began to clean everything for the second time. I then noticed that the top end needle body holes did not line up inside with the fuel nozzle fitting on the carb, and after that change she runs!!

Thanks for everybody's input

Mugen is not very helpfull either. I asked about replacing a broken carb, and I was told to either buy a new one, or send it to GRP in Italy.

Your right robbie!! I should have just walked away from the problem, and come back with a fresh head, or contact Mugen. The engine turned out to be fine. I guess I have a case of foot in mouth disease.
