Sea Level '04 wr450 jetting

Hi there,

I'm over in the UK, but just got a canadian spec bike. Will order the JD kit, but i want to get the bike going asap. With the butt plug removed and no other mods, what is a good first guess for jetting at sea level and 70F?


HI , try the stock jets, should be a 48 pilot, 165 main clip in 4th position, if it splutters at steady throttle opening, disconnect the tps at the carb. :thumbsup:

im at sea level and im running a 170 main and a 50 pilot. seems to be running quite well.

165 main, JD Blue #3 or JD Red #4 depending on air box mods and pipe. :thumbsup:
