I'm working on getting a 99 KLR650 running again and when I got it it was all taken apart. I've cleaned the carb and now I'm trying to figure out where all of the hoses go. I know that 2 is where the choke (enricher) screws in and 4 is the main fuel line from the bottom of the petcock. Where do 1 & 3 go?
Also, where does the line on the back of the petcock go?
