Sawzall should be the red rider BB gun of Gen X kids! Everyone should get one! But don't put your eye out with it!
I'm on the fence about a build as well...I've had 250R Honda's in the past, but after a ten+ year hiatus I want to play again..I rode a stock'ish Banshee and loved the power, but hate the ergonomics...I'm thinking YFZ450R swap..
Good luck with your build, sorry to hijack the thread. Just reading and learning...
