I don't know how true those outputs are or where Kawasaki measures the 49.4 HP. It might be on the crank or something. The reason why is say this, is that some aftermarket exhaust shops get very much lower readings. HMF Engineering got a RWHP output of about 30 HP. Yes you can say that the results where achieved with stock tires and you need to add about 9HP to get slick tire RWHP. This pushes the RWHP to 39 HP, still 10 HP less that the factory claims. Where is this HP lost, CVT & drive shaft? The KFX700 have lower RWHP outputs that the Raptor, DS650, Predator and the YFZ450.
One thing I like about this bikes power delivery is how low it makes max HP and how smooth the power curve is. It’s got train like pulling power. (Based on HMF Engineering’s web site)

Hp from factory is measured at the crank.
Most bikes are dynoed in a direct 1/1 gear, ie. 4 or 5th, to get rear wheel HP.
An auto can't be dynoed, with the same results as the standards. how do you get 1/1 on an auto which is always trying to gear up. An auto will always get lower HP reading than a standard for that reason, when rear wheel HP is measured, because it can't be keep in that 1/1 gear.

Thanks all,
I feel that there is more ponies above 6500 RPM than the manual states. One just has to unleash them. Since I am piped, that should raise peak RPM hp a few hundred RPM. I have learned never believe what the manufacter says. I am looking for a power curve from a Dyno-mite or something similar. Doesn't really matter if it is crank or RWHP. I want to set the primary clutching to run at peak HP then
worry about getting it to the rear wheels

How do you like your MBRP Duals? I have been thinking about getting a set but havent talked to anyone who has them. Did you notice much gain? Whats the sound like? Are they loud as heck? I would prefer somthing under 96db. Yoshi's are supposed to be rated at 92-94db but thats alot of money for an exhaust. I figured i would wait a while and if i cant find anything else order the yoshis.

I have the MRBP's also and I love them. Having said that, I don't have anything to compare it to, other than stock. A buddy of mine has the Alien exhaust on his KFX400 and it's loud. I find it kind of "blatting" loud, and he wears earplugs when he rides.
There was definitely a performance gain when I put them on, but how much, I don't know enough to say. The look and especially the sound was worth the cash though.

There is about a 3 to 4 hp gain ( from Alltoys) with these pipes. I just recieved my Dalton weights today. They are about 3 grams heavier with holes for Yami rivits. If piping a Quad is like piping a sled, heavier hitters in the primary will bring more power yet. I am going to do some testing with springs and the weights this Sat at Alltoys place. I will post the radar runs next week
