Yamakaze, I would have to agree totally about having the nads to make it work. Out of the box, my 450 was a joke. I was disapointed about the power, and how corked up it was. But after makin the mods, adding a few other goodies, it runs like a raped ape. The only other thing I want to find is a decent tire setup for the beast. The stock rubber sucks!. I think that is the final piece of the puzzle(until some other trick go fast part comes out) Until then, I will ride it like I stole it! Machster "Live well...ride free"
