I want to know how much HP a 400Ex really has, I have read 27HP, and others, but my Title from my EX says it has 34.2 HP. Who knows the answer to this question? thanks

I saw a stock 400 on a mobile Dyno at Red Bud run 26 and change. The modified 440's were running 35-37. This is of course at the rear wheel.

TRX440's right.... If you want to see actual dyno runs - goto GT Thunder. He's got quite a few stock vs modified runs and an exhaust shootout...

Maybe 34.2 is at the crank, I know the ones at GT Thunder are at the rear wheels.
