KLR650 Carb Hose Routing

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?

Thanks

1 is your vacuum port.It goes to your petcock.
3 is your vent line.It goes down to the bottom of the bike and remains open to atmosphere.

Good point; the Generation 1 KLR650 engine, without a tee mod, is more reliable without any carb breather hose at all . . . at least, during water crossings 10" or deeper! (Do not ask how this fact is known. )

Rather, "2," I think.
