isn't the 14t front sprocket the stock size on the 05-06 400ex?

i have a 2002
i took my front sprocket off tonite, its was a 14t, i replaced it with a 15t.

from every thing i have read, it shows the front sprockt being a 15t as stock...

im getting a little noise on that front sprocket now though. i think the chain guard on the chain guard assembly (housing and guard) is rubbing. im going to try taking that piece off and reinstalling the housing, to see if that gets rid of the rubbing.

i noticed a little difference though.. it feels like it has anotehr gear, the bike has no problem pulling with the 15t.
maybe i will put a 16t just for test :eek2:

im runnin a race cam, 11:1compression piston, piped n jetted.. o yea and i put a rev box in today also.. raised my top end a good bit, expceially with the addition of the new sprocket.. i used to hit the rev limiter often, but now.. i can wine those gears out a little bit more w/o rev limiting..
