The WR450 is alive and well. The Carb has been cleaned.

So I finally got some time ot get to the bottom of the carburetor problems on my WR450. It had a stuck valve on the float bowl.to fix this I had to take the bottom of the carburetor off, meaning the float bowl. Once I had this off I took the float off. The little valve with a rubber tip was stuck up into the chamber that it slides in and controls the flow of gas into the float bowl. I wasn't sure this this valve works and it didn't seem to want to come out, so I gently tap on it with a little screw driver. It turn and freed up and gas went leaking out all over the place. Yup I found the fix. so I took that other parts around this off and made sure that the hole was clean. I also took off the brass fitting that holds the gas line hose from the tank. this is a direct line to the float bowl valve. Once this was all clear I put it back together and fire up the bike. Perfect it runs without fail.

Now I just need to adjust my Fuel Air mixture. I messed up my setting the last time I was trying to get the bike to run. I was silly and took out the screw without checking the setting. Once I realized what I had done, I thought man that was a mistake.

Well anyway now if it would stop snowing here in Utah I will pack it up and go for a ride.

My WR450F is dead, Here is what I have tried.

I am sorry to say that the winter storage of my WR450F this year lead to it being hard to start the first time I fired it up. It kicked right over and ran for a minute, sputtering and coughing. I took off down the road and around the corner, I was able to make it back to my driveway and it stopped. It hasn't started since. I am able to run it for a few seconds by spraying starter fluid in the air box. This means the bike is starving for gas. I took the bottom the the carburetor off and a few of the jets. I could not find a clog. What I think the issue is a plugged up something in the carburetor. I think I need to do a carburetor clean and rebuild. I think the passage way through the top of the carburetor into the lower bowl that is controlled by the float is plugged. I tested this by opening the drain valve and the gas tank petcock and gas did not flow all over the place. I think I will do a full carburetor removal and cleaning. I am also going to toss the old gas and clean out the filter in the bottom of the gas tank. I did test the flow of gas from the tank into the carburetor and this was OK, but this little bit of maintenance sounds like a good idea. I will keep you posted on my results once I get a chance to work on it.
