As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Ok I had to completely rebuild my engine. But when I got to me carbs I changed to air pods. Now the question is what do I do with the two large vacuum line that ran to the air box. Do I block them off, run them to somewhere else. Please help
 
I don't think those are vacuum lines but vent lines. You can leave them open to air.
 
ok I wasn't sure what they were I could find anything on them in the manual. Thanks.
 
Just in case you didn't know, you will need to rejet the carbs with the installation of those air filters. Dynojet kits have a good reputation with the folks that use them here. Also, there is a big difference in quality between some real K&N pods and the cheap Emgo filters. Big price difference too. Pods from the likes of APE are decent quality but much cheaper than K&N's and a lot of forum members provide positive reviews of them as well.
 
I have the jet kit and I bought the K&N pods. I have the factory air box but the rubbers are bad, and the pods were cheaper than the air box. That is why I went with pods. It already had a four to one exhaust on it. So I figured go the rest of the way. I am making it into a caf? bike. The pods give it a little cleaner look that I like. Thanks guys.
 
With the kit do not use the vent hoses.
The T's open to air is what you want.
 
Now the question is what do I do with the two large vacuum line that ran to the air box.

Any GS I have ever seen only has ONE line connected to the air box, and it is a crankcase ventilation line. It collects the vapors that are created by blow-by in the cylinders and allows the carbs to pull it through to be burned.

OK, some bikes have had a drain line connected to the bottom-left corner of the airbox, but that one should be rather obvious, as it is not connected to the engine.
