Again boys a built 1441 motor is not the same. This motor has to come with a warranty and be reliable. Here is an example, I live near Carpenter racing and I have spoken to bob himself. Actually talked to him last week about the 14r. From the factory the are still tuned down a lil my guess for warrantys. He has one now with a cleaned up head and cams that he so far has dynoed at 244hp. Give them a call their great guys and will answer all questions. He is also one of the best engine builders in the game. He said to me with his basic head and cam package I should see 225hp or so with regular gas. And that's how it should come from the factory but they need to warrant the engine for a year so it needs to be tuned down a lil. As you should all know NO ENGINE BUILDER will ever give you a warranty. So from kawi or any bike company you'll never see a FULLY blown race engine from the factory. It needs to be fully reliable as much as possible. Like I said good racers around the country that went from the busa to the 14r have gone faster on the 14r. But again they should it is a bigger engine. And I really hope the busa does come back SOON with a 14r killer because it would be grest for all of us consumers.
