Help in Mexico -- 2003 WR450 Starting Issues
Posted February 14, 2008 - 05:11 PM
So, any diagnosis? Am I one of the lucky 2003 WR450 owners who has just experienced the woodruff key failure? Can the bike still be started without causing further engine damage even if this woodruff key issue is what´s wrong? Where should I check to see if this damage has occured?

Since the crankshaft timing chain sprocket is cut directly on the crank, that shouldn't be an issue unless there is a tensioner problem. Only the ignition timing depends on the key.
any further starting attempts may just do valve damage(piston contact).
CDI, or other ignition failures are, of course, a possibility.
