Well.... I just sold my YFZ 450 today. I got enough to pay it off, pay next months rent, and I'll have about 250 left. I have a 2013, 086 and my RTR pipe. I want to get an engine and bump box but I know I'll need a pipe was just hoping I could put it off for what I got for a couple weeks so I could get the box.... The AE comes with a POS drill start. I know 250 isn't quite enough but was hoping I could get close to that number and give the Go's a try. My other option is to get a motor that runs with the 2013 or 086.... know what I'm sayin....
