Mud in carb

10 posts in this topic

I have an 04 wr 450 and I went to install a JD jet kit and when I pulled the bottom off there was a large amount of mud right near the hole for the drain. Yesterday we went riding in wet and muddy conditions. The bike stalled a couple of times in wet mud. I had a real hard time getting it started and keeping it running. I pulled the filters out of the gas tank and they are totally clean. How can mud get into the carb? My air filter was fine also. Cheers S.

it may have come in the vent hoses,reroute the two that cross over the top of the carb. make them go past the battery into the airbox,and just let them dangle down in there. why yamaha left lines that suck air down in the dirt would be a good debate question! :cry:

Are the two hoses the ones with the black plastic clip holding them together? Directly over the front top part of the carb? Thanks S.
