what do you guys think about a ninja 250 motor on a 400ex. I would buy a good used frame because mine is junk, i ride the bike with a 416 motor but i had to do some frame repair. but do you guys think that it would be bad ***. i should be pretty fast i would think, is it worth it?

yes, it was in dirtwheels several years ago. it was very heavy. they said it was a torque monster though.

what are the torque and HP numbers on the 250 ninja?

This is the best i could find

Kawasaki Ninja 250R is powered by a 249cc liquid cooled, parallel twin, DOHC petrol engine which develops a maximum power of 32 Bhp at 11000 rpm with the maximum torque of 22 Nm at 8200 rpm. The Ninja 250R features a revised six-speed transmission for smoother shifting and works on a more durable clutch. It also features a new radiator to provide better cooling without adding extra weight to the bike. The engine of Ninja 250R has been refined to deliver smooth, step-free power improving low- and mid-range power to offer rider-friendly response. The combustion chamber has been so designed to optimize combustion efficiency and reduce emissions.

is there a weight on the engine? maybe with some money into it you could get maybe 45 or 50+ HP put of it.

either way it would be a cool build.

that would help because there is already radiator mounts. plus there is alot of room in that chassis.
