Leaking Gas from Carbs - Multiple Issues
Been searching around a lot on this site and thought it might be best to just post some pics and ask. First off, I have a 1985 VN700A, so it may be a slightly bit different. My bike was leaking gas from around the location of the air cut-off diaphragm on the left side of the bike. I'm not sure if this was the only place but I know it was from at least there.
Now, I don't believe this should be possible as gas shouldn't get past the petcock into the carbs as there shouldn't be a vacuum right? So there's likely a problem with that. I have a Res, On, and Pri on my petcock and if I open the drain valve in any of the 3 spots gas will just come out non-stop.
Also, I opened up where it was leaking and saw that the diaphragm seemed pretty shot. It felt more like paper than rubber and when I looked behind the diaphragm the rubber was all cracked and pretty shot. The one on the right side of the bike looked and felt great (pics attached for comparison.) Also, the left side was pretty dirty while the right was pretty clean. You can see in the one pic of the caps, the one on the left was after I had already cleaned it a bit! I didn't touch the right side.
So I'm looking for some feedback, what do you think I should do? I've already drained most of the gas so I'm thinking that removing the tank and pulling the carbs is probably in order. Seeing how gunked the air shut off area is the rest of that carb is probably pretty bad. Should I also look into taking apart the petcock? If gas is flowing freely something probably needs replacing there, just not sure what. Should I try to rebuild it? Can it be replaced? I took the bike out for a ride before it started leaking bad and it honestly ran like a top.
