Just spent 1/2 hour reading the thread on thumper. What a discovery! I don't even own a WR but found the info to be pretty amazing. Lots of friends considering buying one, and this certainly helps with the yz v. wr thing. Couldn't get one myself, as I didn't come close to being able to touch the ground. (bought a klx300. 3" lower). Now if only my klx had that grey wire.......
I posted my feelings about the WR when that tread was just a rag on the bike, and now look what has happend. There are over 105 posts and I'm sure there will be 105 more. The fix will rock the WR's world and Yamaha will have something to explain if this really pans out. I'm very excieted and will try the "free Mod" when more testing has been done.
Just did the mod. Used my extra small screwdriver to push the connector out. Used the tank and seat off to reroute my hoses. The bike pulls hard with no hit.
I live at 5500 feet, stock jeting, 1.5 turns, screw cut, muff plug out.:)
