Hi, I have a 1994 KLX250, non-street legal model. I have the stock carburetor but I can't figure out what the top hose port is on the carb. On the left side of the carburetor is two hose ports that look like they should have a hose connected to them. The bottom one is the fuel inlet port, but what does the top one do? It runs fine with that upper port having no hose connected to it, but what is it there for? KLX 250 owners, can you look at your carb and tell me where that upper hose port goes to or what it does? Thank you in advance! -Steve

 

Steve, Do you have a pic you can post of the port? Most of the people on this forum have the KLX 250s that started being produced in 2006, BUT a lot of the stuff is still the same from the older klx's, and there are some sharp guys on here.

Here's a shot of my carb, do you see the port in question? The top black plastic port is just a vent, and should be routed down under the bike. That the one?
