Hi Mike,,

It's nice to see you offering your total support for the Ninja engines on this forum. It shows how supportive you pros can be sometimes..

On the other hand, I would like to ask for your opinion on Ninja .21R01A. How would you rate it among the top brands such as Sirio and Novarossi?? I was hoping to find a product review of this engine online or in any magazine but haven't been lucky as of yet. So maybe you could enlighten us with some inside knowledge or tips on this matter..

Thanks again champ and good luck in your future races..
