I just bought a 2001 wr426, it's set up for the road. The problem i'm having is the midrange power seems to be a garbally (if thats a real word) at a constant speed on the road. It starts fine, idles well, and the throttle response is unbelievable, pulls like a monster at full throttle, i'm wondering if it might be running a little bit rich. It does backfire a bit when i gear down and slow down, but it does have an aftermarket "silencer"(doma), the neighbors must really like me. Any suggestions? I would also like to get a bit more speed out of it, as i'm ridding it about 25 miles to work on the motor way (freeway). It also has a bit of a white milky drip coming out of one of the vents, any idea what this could be?
