I had the opportunity to ride a 2012 WR450 this weekend. Well I think he has missed some of the free mods and I don't know what they are. I can see that he has removed the peashooter and the snorkel in the air box and he told me that the dealer had checked the valves and remapped it. Other than that I think it is stock. To get to the point it is still "weak" compared to my 07. He is coming off a WR250. He is the second owner of the 2012 and he was happy with his "new" till he rode mine and I expected to blown away with his. I will say that it handled much better but was severely lacking in power. Not 250 range but not up to what I expected out of a 450. is there something that the PO could have done to this bike to tone it down or is he missing some free mods? shouldn't a 2012 be able to kick an 07 with the fuel inject? I told him about this forum but he is not a "computer person". He is more of an old fuddy duddy than I am.
