Suggestions sought-new 05 WR450 running lean
Posted September 24, 2005 - 12:52 PM
I just got a new 2005 WR450F. Right at the dealer I noticed that the bike is running way lean, more than I expected. During my first ride at Hollister OHV park in CA I confirmed that it does run lean although much less so when the bike warms up. At the beginning I had to fiddle with choke and idle screw (?) to prevent the bike from stumbling.
I'm looking for suggestions on what to do to fix this. I'm not looking for all-out performance mods as I want to keep the bike mostly stock, at least for now.
I looked at this http://www.thumperta...ad.php?t=230021
but, frankly, it seems more than I want to do.
PS. I did remove the hrottle stop.

With that out of the way, consult Indy450's jetting chart and it will get you damn near perfect based on your temps and elevation. If you don't want to buy the JD Jetting kit with extra needle, then at the the very least, you'll want to invest in an '04 needle as the '05 is not adjustable. And there you have it, stock, but not totally stock...SC
