There is no cam that will increase the top end horsepower without taking away bottom end performance. Engine dynamics just don't work that way.

The v2 has so much low end I have never wanted for more but the mid and top seems to be a little insuficient. . Compaired to my old Prairie 650 or my buddies BF 750, or even a Polarbus 700 the top end is real shy on my AC. I can do 51 in low and only 53 in high
Yup, I don't know SH!T. You ask a questtion and you know the answer so I figure you are what you say you are. So go ahead and believe the advertizing hype. I love it when guys like you spend their money then whine you didn't get what you paid for. Well, if it sounds to go to be true then it is. I've forgot more about engines than you will ever know. You just went on the ignore list.

You have no idea of mods becuase you are so lame you don't want to go faster.
The only one I hear whining is you.
Why don't you go on the PepBoys ATV forum as I think they are more your speed.
I've been faster than you ever will go on your quad, sonnypuppy! Tell me about the records you've set or the championships you've won in any sport. Also tell me about how you worked as a professional race mechanic. Then I will believe what you say, otherwise you are full of crap and know nothing about engine dynamics.

Yeah, the rider, no brains or skill.

So I fattened up my jetting to 147.5 and 145 R/F Kehin jets and I saw a notocable improvement in top speed. 53 low and 58 high, this was on a sandy railroad bed with my 27" mud lites. The speedometer is pretty accurate, I checked it with GPS. Man the motor is screaming at 53 in low. I was riding with three buddies, two Can-Am 800's and a BF-750, man those machines crank. Suspension wise I could easily stay with them in all area's except all out excelleration but that was not real problem due to NH speed limits. One of the Outlander boys was actually impressed at my suspension as he kept banging his frame in the rocky area's, where I could clear without issue.
They both complained the the Outlander suspension does not live up to the motor and it very easy to overwhelm the suspension and brakes.
I think I enjoyed riding the BF most as I found the suspension to be a good mix of ride quality and handling.

I just got my 06 650 v2 up to 65 on pavement over the weekend. I have been listening to v2 rider and staying under 40 in low. I was at my dealer today and he said I could go as fast as I want in low gear. He didn't tell me how fast it would go in low but I will use the 40 and under rule.

A higher performance cam alters the duration of intake and exhaust valves to maximize performance within a certain power band. Since the valve timing is controlled by the cam, and it is set to a fixed duration, the timing can only be optimized within a certain range of engine rpm's. A good low-range cam has optimal detonation when the piston is moving slower, but as the engine accelerates, optimal detonation may occur later in the stroke, when the piston is not in as optimal of a postion to transfer the power. Remember that the process of detonation takes the same amount of time no matter what....getting the engine to better capture the power of the detonation within a certain range is the purpose of a different cam. This is why Variable Cam Timing is such a big deal in some of the new cars. They really do make a difference in the entire powerband. To the best of my knowledge, none of the ATVs on the market have variable cam timing. Hope this explanation helps.

You can get a cam or dual cams from your artic cat dealer and yes they do help a lot in low, med, and high range. You can do it in the machine.
