Has anyone tried to disconnect the Grey CDI mapping wire under the gas tank at the black dbl connector? This seems to have helped eleviate the mid range bog that is noticable to me on my 426 & to the owners of 2001 WR250's. My bike is out of town til Sunday, so I can not check to see if this works/applies to the 426. For more info check the WR250 forum, under "what is wrong with the wr's" I need some feedback asap. Thanks This only will apply to US-spec WR's, not sure about 1999-2000 WR400's. The wire is solid grey, next to the striped wire.
