no, there's no hp difference between any year. stock is around 25-27.

you many know better than me, but im going buy what the dealer said and by what the white bros exhaust booklet said for a stock 400. idk if that was at the engine. i just remember the 00ex being 32-34 and the 450r being 43-45, and the crf450 being 55.

I am going by what i was shown in the white bros manuel and the dealer.

those could very well be what the engine puts out.. but by the time its put to the ground its significantly less.

true, they say for cars atleast 15% of the hp is lost from the engine to the wheels.

[2007TRX400EX]

I checked it, its about a 15% difference.

I'm going to say more than 38hp going back to the original posters question. I'd put money on 40hp.

440 at 12.5:1 w stage 2 cam and yoshi exhaust. 40hp

My woods EX put down 38 with a 426 at 12.5:1 w stock cam and DMC Alien full exhaust.
