Big Bore Options for an 07

[BigVince]

I have about 2 grand to spend on a proven badass big bore kit. What would you guys recommend? Remember... i have an 07 450.. not an 04 or 05. Please advise

Max Power Rpms has a IceCube 488 kit for $1250.00....and then they have a 522 kit for $2570.00!!! Both tested and proven for serious horspower..and they both run great...only thing i recomend is if you go with the 522 kit then you are going to have so much power that you are going to need to up the suspension...that much power is wayy too much for stock suspension on a 07 450er!!!

I do not know for sure but I heard of a 564 kit a freind of mine was talking about I think he said N-Motion makes it. He also told me Hotrods is now making a +2mm stroker crank for the 06/07 that will make it a 470 by only changing the crank. Only costs about 300. Like I said I don't know for sure maybe sombody here could tell us more.
