I am thinking about changing my carb settings to the 2002 yzf specs. I have opened up the exhaust, disconnected grey wire, lid removed, and yz throttle stop so far. From reading some of the past posts I think I would be a good candidate for this because of the mods done. I ride in Michigan and was wondering if anyone has any suggestions or tips before doing this. Also does anyone have the carb specs for the 2002 yzf 426. From past posts I have seen some info on the air cut valve and understand that the yz does not have this. Does the 2002 wr have it and will I have to plug it when changing to yz carb specs. Any info will be greatly appreciated.
