Okay I am still playing around with a couple of leaks and I have no clue on one and posibly know why on the other one. The first is from an area with a bolt clamp on the left side of the bike (if sitting on it) right by the center stand.



Here is a picture from a little different angle to show location a bit better.



Yes my daughter likes to park her "bike" next to my "bike" lol. What issues might cause that leak and what does that clamp hold in place?

I am also posting one just for verification. I want to make sure that this picture is showing the vacumn line going from the petcock to the carb (the most obvious line anyways). It is slightly cracked at the top where it goes into the petcock and I know I need to replace it. Could that be why I am getting gas leaking from the carb into that line? Could that affect the other leak at all? I am very new to this so please continue to have patience with me. I appreciate all the help that everyone has given so far. This is really a great community.

Hey, Kirk - in those first two pics, it looks like the leak is coming down the pre-muffler chamber on the left (sitting on the bike) side. The clamps in your pic hold the muffler onto the pre-muffler, so nothing about them should cause any trouble. And you're sure it's fuel, and not anti-freeze or oil? Or even gunk from a regular battery? There's a vent line off of your fuel tank, but that line sits in front of your exhaust chamber thing; there's an overflow line for your anti-freeze towards the back of the bike...but it's on the other side. And it sounds like the bike isn't running yet, so it's hard for me to see how that could be blow-back from a spot way ahead of that.

Yes, your vacuum line is hooked up correctly, but that also shouldn't affect the leak. However, the fuel line coming off to the right of the vacuum line (looking at the pic) appears to be crimped there at the bottom where it makes a 90-degree turn towards the engine block.

My gut sense is to pull the carbs and see what your fuel lines look line on those...but I'd let someone else weigh in before doing that. :confused: No, wait, I've changed my mind - my gut sense is to pull your exhaust system and see what's getting in there - on second review of those pics, it looks like something's coming out of where the muffler attachest to the premuffler.

Kirk, the fuel line that is kinked, turn the outlet from the pet cock round so it faces directly into the carbs, if its stiff to turn, spray a little WD-40 on it and leave it a few minutes.

Yeah I quickly put the tank on hoping I had found and fixed the leak but no such luck. I didn't wory about the kink in it as I was only going to have it on for a couple of minutes. I appreciate you noticing that though. It is great that everyone is offering help and support. It makes it so much easier for noobs like myself. I am going to take off the muffler and try and figure out where the gas is coming from and why from there. It is definetly gas.

The fuel line connecting to the carb is rubbing up against that large nut on the engine, check and see if it has worn through there. It looks like if there is a leak there, it would run down to that clamp you mentioned.

HOLD UP A SECOND!!!!!!!!!!!

in the first pic, The silver clamp in the foreground...just behind the exhaust heat shield, is all black and wet, is that the leak? if so the engine is seriously flooded and is dumping fuel through the exhaust.

Yes that is the leak and that would make sense as the only time it comes out is when I attempt to start it and then quite a bit comes out and fairly fast. What might the cause be and why so much at one time when I only press the starter once or twice. The engine isn't catching (guess too flodded to catch) but would that be the carbs being bad or the petcock releasing too much gas maybe? Bumpy750 told me that my petcock might be bad. I am hoping its nothing too intense as I am still learning but only time will tell. Once again I appreciate all the help so far.

That leak is on teh Left side, That would be the rear cylender not the front.
You may have a stuck float in the carb causing a major flooding condition.
Your oil will be washed out to if this is the case.
Check the overflow hose from the carb, it drops down to that area to, that may be leaking and just dripping on the exhause.

Oops, sorry, you're right, Chad: rear cyl, not front cyl. But I think you nailed it, Bucky, that it's fuel/oil coming out of the cyl and into the exhaust system (and no need to apologize - I hadn't said specifically that's why I was wondering, just that it seemed an odd place to be getting a fuel leak...which it is, unless the engine's flooded!).

Isn't that the vacuum line? Still would be a good idea to check it though.

It seems to me, that if it's a fairly large amount of fuel leaking, it would be coming from a leaking line or the carbs, rather than through the engine (as from not firing in the cylinder) but there's not much of a way the fuel would get to that area of the exhaust from the carb area ????

Is the bike running when this leak happens, or is it just from trying to get the bike started?

THat is the vacuum line against the nut (I think that's some other cam chain tensioner...), but it doesn't seem to be getting crushed in there. The crack at the top of the line is more disconcerting. But the fuel line (to the right) has a good crimp in it and could be cracked...but I still don't see how the fuel's gonna work it's way down to the exhaust like that unless it's something dramatic.

The vacumn line appears to be on the nut but it isn't actually touching. The only fault that I can see on the vacumn line is that it is cracked at the top where it fits onto the petcock. The fuel line that is crimped int he picture was only that way because I put the tank on real quick to verify where the leak was so I could take pictures. When I had the tank on previously to that, the line was not crimped and the leak was in the same spot.

I have had the choke on the entire time, as it had been sitting for 2 years and hasn't run since then. Should I not have the choke on full? Could it be flooding the engine like that? I am sorry for asking such noob questions but this is the first bike I have ever tried to work on.

If it has been sitting for 2 years I would guess it needs a good cleaning.
Try a good dose of Seafoam.
Works great and you don't have to pull the carbs.

Okay I add that to the gas, can I pick it up at a normal autoparts store like pepboys or advanced auto or do I need to go to a motorcycle shop for that? I really appreciate all the help from you guys.

Update

After re-charging the battery I put my tank back on and with the fuel off I put the choke back to normal and attempted to start it a couple of times hoping to use some gas that was in there to keep it from flooding. I then turned the gas back on and attempted to start it. It didn't want to catch but it tried, I could hear the exhaust starting to fire up. The good news is that I didn't have any fuel leaking from the muffler. Does this mean that the choke was flooding the engine? Is there anything besides the choke that I can do to help the engine catch and stay running now?

Try opening the choke just a little bit and see if that doesn't get it started. You can see the plunger on the rear carb easily - maybe take a look and see what's going on there as you move the choke cable around. Also, the problem with the crack in your vacuum line is that no vacuum, no fuel - so I'd replace that first off. Also, in one of your pics, I noticed that there were no covers on your air filters- you may have been "in process" at the point you took the pic, but just in case: make sure your airflow system (ducts, carb boots, vacuum lines, etc.) is back together before trying to start it up.

Okay, I replaced the vacumn line and tried again. The bike wouldn't really start to catch until I turned the throttle a little bit. The bike also did not leak any gas until I turned the throttle a little bit but it started but died almost immediately. I tried the throttle and it caught and died instantly. It seems like it isn't getting enough gas until I turn the throttle and then it floods. After that happened I realized that is what I did the last time too.

The gas is not coming out of any hoses or drain hoses, it is coming directly out of the same place as indicated in picture #1. I put some seafoam into the gas tank hoping that might clean it up a bit incase anything is sticking in the open position. Any suggestions? I am so close I can taste it, just can't keep it running. I did put the air filters back on before tyring this.
