Well, I just got my new carbed setup goin, and have noticed something weird. When I drop it down to 1st gear on my 700R4, and shift it manually to 2nd, it HAULS ***!!!! But, let's say I'm cruisin at about 30 with the shifter in overdrive, and I nail the gas. As soon as it downshifts, I get a serious bog problem. It makes the weirdest noise, like it just burped through the intake (no it wasn't a pop, so it wasn't a backfire). Then after a second or two it runs okay. Why does it do this only when it downshifts automatically, and not while doin a straight shot through 1st or 2nd? Any help would be greatly appreciated. Thanks in advance.
