The numbers I've seen are 32HP stock.

 

packardbell15, glad to see that you bite back. This is what Popular Mechanics said.

Kawasaki's Prairie 650 blows every other ATV into the puckerbushes. Why? Because it's quicker, faster, better handling, shorter stopping, more comfortable, more versatile and just plain cleverer. The heart of this 65-mph monster is a 633cc, 90° V-twin, the first V-twin in any ATV. It has every state-of-the-art feature, including single-overhead cams operating four valves per cylinder, liquid cooling, an alloy block with steel liners and a pair of Keihin CVKR 32mm carbs similar to those on Kawasaki's Ninja sportbikes. This lightweight powerhouse produces 42 hp at 6500 rpm, boasts a flat torque curve from 3000 to 8000 rpm and smoothly revs to 8500 rpm. The Prairie 650 weighs 606 pounds, giving a ratio of just 14.4 pounds per horsepower. No other four-wheel-drive ATV even comes close--even if they're foolish enough to try.

 

like I said..right from the title 42hp

 

packard...settle down...take a joke!!!

Mine says 42 on the title...and the mods, I gotta be able to out run my buddies kid on his daddies 650...(Not a joke)

 

Well, am I joking p-bell? I have several people agreeing with me on this one!!! It is on the title for some of us

I keep giving you correct advise and answer your questions

I am done now !!!!!

if this is the thanks I get then you are not getting any help from me. I'll join the crowd that doesn't waste their time

 

bigtime...I'm with you, I guess you might call this a black ball.

 

Sounds good encore!

How do you like the black and red spring combo by the way?

 

in atv magazine, i thought i read that the 650 had like 31.4 or something, i could be wrong, though.

 

I believe the 31.4 was from the back tires...not motor.

red & black combo...I love it! If all I did was technical riding, I would only have the black. With the red spring, you need higher rpm to get you moving but when you get comfortable with your bike, you learn how to take off just as easy as stock. I like the red spring for the increased hp at take off. And the black spring for the way it grips the belt. Some will disagree about the red, some say it can be dangerous, for some, it may be, but not me.

 

sounds interesting.... I still like to wind it up till it won't go any faster, so I might be pushing it with even just the black secondary spring; heard it isn't good to be running high speed with the black (although it is still possible to hit the same speeds as before)
