stuck on stupid

[j.w.napier]

how goes it. i'm j.w. and here is my problem. i bought a 79 gs 750 l in march on this year this is the first suzuki that i have owned. so far no big problems working on it. i recently found out the carbs had been jacked up so bad that i had to replace them. (thank god for my mom even at 32 yrs old i still get good day presents \\/), so i bought a set off ebay 78 gs 750 ? don't know the exact model didn't give that info? anyways where my fuel lines hook up on the carb are different than my orginal ones. the original had a connecting tube - a tee tube - and another connecting tube. how ever on this one i have a tee tube- no tube - and another tee tube (<original> carb, -, carb, T, carb, -, carb) (<new one> carb, T, carb, nothing, carb, T, carb) no that i've made a fool of myself trying to explain this can anyone tell me wher all of the hoses go? i know the 2 tee tube are my main fuel i think but the other 2 are? return air vented? why are there two main fuel inlets? if you can make sense of any of this and can help i would be very greatful. thanks j.w.

Assuming you have the correct VM carbs for your model:

-You have a plastic T-tube inbetween #2 and #3 carb. That's where your gas line from the petcock hooks up to. Straight tubes should hook up between #1 and #2 and then between #3 and #4.

-Then you have vent nipples on carbs #2, #3, and #4 of the left hand side of the carbs toward the back, facing up. #2 and #4 vent to air (hook up to nothing). #3 hooks up to the petcock and is your vacuum line.

In stock form there shouldn't be two "T" fuel inlets. No clue what that might be about.

Only explanation I can think of is that you have a custom carb setup. Normally each carb is different on how it is setup for fuel inlet and vacuum and venting. The only possible way to get around this would be to mount the carbs this way on the rack, #1- #4, #1- #4. #2 & #3 couldn't be used since the fuel inlets go straight thru. With this 1-4, 1-4 setup you would have to use a non vacuum petcock as the vacuum tap is on #3(or tap off of one carb sync port). This would allow you to use a T in between # 1 and #4 on each side, and run 2 seperate gas lines to the carbs. It is possible this was done for racing purposes, to allow more gas flow to the carbs. A picture of each carb rack would help identify what you have going there.

rejetted maybe for performance?

when i tore the new set apart to clean them they had 110 jetts in it maybe it was set up this way for performance? j.w.

Sounds reasonable, especially if they had pod air filters and some aftermarket exhaust.

I know the "if I keep this up my bike will be brand new" If you're like me when you run out of things to do you will get bored and create things to do.
