What ever you decide just do yourself a favor and do it right...don't cut corners or be someones geaunie pig...mrhp is a top notch guy and will treat you like a friend instead of a p-i-t-a and will offer good advice on where to start so you end up where you want to be. I have the 14:1, lectron 46hv, porting, valves and springs, endcap, and web 109s and she puts out awesome torque...

I would highly suggest the following mods to start...ported intake and billet endcap...then the carb...then cams and piston and headwork if your even interested in going there. You'll be pleasantly suprised with just the first two mods! Thats all that is on my 03' and the only other item I'd put on would be the Lectron 46hv...this quad is a blast to ride and wheelies very easily.

 

I have the stage II
I have the 11.5 piston as I need to run pump. I ride trails and fill up at hole in the wall shops.
I have the A1/A2 cam combo with the HD vavle springs, 60% clutch springs, RW - CDI (For sale), ported intake, lectron 46hv carb and the FMF pipe.
It really woke it the $%@# up!!!
If you get the 720 its about 800 more I believe but its fast!
how fast can you afford to go?
