So I just bought a 2004 XB12R used from a dealership. It has an aftermarket can, with no brand name tag on it. It greatly resembles a carbon fiber Jardine, but I'm not positive. The bike also has a K&N air filter on it. It has definitely been remapped (maybe too much) because it smells very rich upon initial start-up, and has lots of power everywhere.
My concern is the header. The header on the XB12 is supposed to be 1.75" diameter, right? The header on my bike is the smaller 1.5". At first I was worried the bike was an XB9 with XB12 decals/badges, etc. But the frame is dark grey, and the VIN# says it's the 12. I am quite convinced it is the 12, but is there any way to tell from the motor itself? I know there is a number stamped right on the motor.
My question is this: Is it better, perhaps, to have the smaller diameter header on the 12 with the free-flowing can and filter? This will cause faster exhaust gases, etc. Or should the bike still have the thicker 1.75" header? Would I notice a difference? Thanks in advance.
