Dear manual decompression lever, 

You suck!

Swapped a 2005 WR250F auto decompression exhaust cam gear into my 2001 WR250F. This swap made starting the bike so easy, I can literally do it by hand. For informative purposes, this is in fact a 2005/2006 part number. the 2003/2004 part number (which is 5UM-12180-00-00) is now an obsolete part and has been superseded by the 2005/2006 part (PN 5UM-12180-10-00). I have not seen nor heard anyone using this year of a part so I went for it and can officially confirm the results are identical if not better. I had a shop do my install, which cost a whopping $128.. Best money I ever spent.

Part Number Purchased: 5UM-12180-10-00 from Partzilla
