Hi all- I just took the YZ426 apart to clean it with a power washer, replace chain and sprockets, new air filter, spark plug, and change radiator hoses. Also replaced the main fuel line from petcock to carb.
Bike was 100% fine before I did this today. After I put the gas tank back on, assembled everything I went to start her up. as soon as I turned the petcock to On gas started running out a couple of the tubes coming from carb- and not the overflow tube. one of the tubes comes from the kick-starter side and goes into a T on the upper body of carb.
When I started the bike, warmed it up, revved it a bit, the gas stopped running out. at idle it was dripping slowly. turned the bike off and gas stated running out of tubes again faster.
Any ideas? I am not familiar with this specific carb - did removeing the gas tank and then reinstalling it cause some type of event with the carb?
