I am going from an 06 YZ450 to this 14 WR450 and I am wondering about a couple different things. 1) I have a GPR V2 sub-mount stabilizer on the YZ that I want to move over. After doing some very rough measuring it looks like it will, has anyone done this? 2) I have read several posts about opening up the air box, is it one of those deals where you just need to remove a cover or do I actually need to cut the top of the box? 3) I ordered an FMF pipe and the programmable ECU, anything else I am should be thinking about? (Besides the usual guards and cosmetic stuff).... 4) This thing does not like to start! I am assuming the new pipe and ecu will correct that (and getting some time on it), but is there a magic spell/dance/chant that I should be doing? Thanks!
