KX100 what in the world to do?

[ggamster]

Hello all, I am buying a 2012 KX100. I am 6'1" 190lbs. I am buying this bike for an ultra light trial bike. I ride very tight single track. Mostly mountain bike trails. I have rode my 125SX and 650X Challenge on the trails, but the hole time I am out I just think "damn this is hard. I wish my bike was smaller and lighter." I don't care much about speed. I will never race. I like to do very small jumps and tech. riding with a trials flare to it. I was going to wait for the KTM freeride but I figure I will ride this in the meantime. I want to make this a very light user friendly ride. Please tell me how to accomplish this. I don't mind to spend a little money as the bike is only $3500, but please save the get this bike or that bike suck comments. I need help and thanks so much.
