With the time and money that would be involved you would be better off looking for the bike you want... rather than trying to morph your Warrior or Raptor into what you want.
These bikes are great for their intended use, and they mod up rather well. Is it a YFZ or KFX 450, no way. Not even close. But they are a blast to ride, and a great trail bike. They have their short comings, and they have their benefits.
My take on it is, if you want much more than what a slightly modified YFM will give you... then step up to something bigger. These bikes are on the lower end of the middle sized quads. But they are very reliable, and that's what keeps them going.
My Raptor is modded up more than it probably needs to be, but the bike with the suspension mods compared to stock make it glide over the rough stuff compared to stock. But it still falls short of some of the other stuff out their. Power wise it is only slightly modded, but nicely done, again falls a little short of what I could have for the same money invested. I still love it though.
This is my Raptor, their are many like it... but this one is mine.
