snyper316 Posted March 10, 2017 #1 Posted March 10, 2017 Ok so finally I have ran my bike for 3.5hrs total trying to figure out this leak situation.... Well it seems to slobber on no.2 carb when the bike is shut off... Does not leak while running. What am I missing could it be the bowl gasket? Living life one curve after the other.

snyper316 Posted March 10, 2017 Author #2 Posted March 10, 2017 I will add that it only seems to do it on side stand... Living life one curve after the other. Vroom scooting, thru the countryside.
CaseyJ955 Posted March 10, 2017 #3 Posted March 10, 2017 Is it possible to get a visual on the leak with the air box removed? I think a bowl gasket would leak anytime there were fuel in the bowl depending on where the gasket is faulty.
snyper316 Posted March 10, 2017 Author #4 Posted March 10, 2017 Tried too Casey, it never did leak the hole time box was off that was the first 2hrs of the 3 1/2 2hrs of running Living life one curve after the other. Vroom scooting, thru the countryside.
snyper316 Posted March 10, 2017 Author #5 Posted March 10, 2017 Top that most of that was on side stand.... Living life one curve after the other. Vroom scooting, thru the countryside.
WildBill1 Posted March 10, 2017 #6 Posted March 10, 2017 Sounds like a stuck carb. float give it a drink of Seafoam chased with some Berrymans. Then ride it like you just stole it off the Showroom floor.

Then ride it like you just stole it off the Showroom floor. that sounds like solid advice, especially if you got some ethanol in it. If you suspect a high fuel level you can get the bike nice and level and do a wet bowl level check. When was the last time you were into the carbs?
WildBill1 Posted March 11, 2017 #8 Posted March 11, 2017 Around six weeks ago set float levels cleaned jets passages.
snyper316 Posted March 11, 2017 Author #9 Posted March 11, 2017 Without engine running? Is when it gets wet around intake boot and on side stand, last I ran ethanol fuel was June of 2015!!! I will not put ethanol in it... Also right now I got 3 shots of marvel in it and been running it like I stole it since I got the new box... Ok I guess the question is how do i take the float valve out? Living life one curve after the other. Vroom scooting, thru the countryside.

BlueSky Posted March 11, 2017 #11 Posted March 11, 2017 Why don't you check the fluid level when it is leaking by connecting a tube to the drain and opening it. Compare to the other carbs if necessary. If the level is high you know the needle is leaking on that carb. I used a clear tygon tube that fit tightly over the drain tubes on my venture to check the fuel levels in accordance with instructions in the manual.

I used a clear tygon tube that fit tightly over the drain tubes on my venture to check the fuel levels in accordance with instructions in the manual. I have checked levels on it and that bowl is slightly lower, one other thing it has been doing for a while now is when I put it on the side stand it bogs down slightly then regains idle after a few seconds. But should I do it when the bike is on the side stand?

But should I do it when the bike is on the side stand?. Wet levels have to be checked with the bike level, ie the carbs as level as possible.
snyper316 Posted March 11, 2017 Author #14 Posted March 11, 2017 . Wet levels have to be checked with the bike level, ie the carbs as level as possible. Yeah I check with center stand down but I think I may have figured out what is going on but it don't make a lick of sense to me if that is what is actually going on....

snyper316 Posted March 11, 2017 Author #17 Posted March 11, 2017 But I haven't overfilled it for a while... But oil still seems to spit out the tube when I revved it.... Living life one curve after the other. Vroom scooting, thru the countryside.
cimmer Posted March 11, 2017 #18 Posted March 11, 2017 How full is the oil in the engine? Check it with the bike on the center stand please. Usually we only fill it to the bottom indicator on the sight glass. If you have it at the full mark on the sight class you can get some oil ending up in the airbox for blow by. I have actually disconnected the breather line and replaced it with a filter to help with this issue. If you download the service manual, this is instructions and pictures in there on how to do a test of the float levels with the bike running. They show using a gas tube but I would think clear hose would work also. You are comparing measurement against the carbs. This will at least show you just where the float level is set to. Hope this helps you.. Rick F.

snyper316 Posted March 11, 2017 Author #20 Posted March 11, 2017 Yeah I know how to check the level the only reason I asked about sidestand that seems to be when the issue shows up... Living life one curve after the other. Vroom scooting, thru the countryside.
snyper316 Posted March 15, 2017 Author #21 Posted March 15, 2017 A little update, let the bike sit for 2 days without starting it. Actually kinda forced by the weather, opened the bowl drain screws the ones that appeared to be leaking are bone dry nothing came out, the other two have pretty much maintained there levels, so Bowl gaskets it is just didn't think they would be leaking already as they were replaced last year... But carb was opened several times while I was chasing a crazy miss in the motor.... so fun fun pull the carbs once again I must, dissamble the carbs I must, resync the carbs I must.:bawling:so guess I will be using the gasket set I bought to rebuild the other carbs
ChurchBuilder Posted March 15, 2017 #22 Posted March 15, 2017 Is the gas coming out of the bowls? The rubber gaskets can get hard and leak. Or is it coming out of the drain tube? Those can get corroded and let fuel get by even if they are tight. Sent from my iPad using Tapatalk

The drain screws seem fine not to mention the carbs are wet above that area... Living life one curve after the other. Vroom scooting, thru the countryside.
van avery Posted March 16, 2017 #24 Posted March 16, 2017 Just a thought. There is a brass hex plug on the back side of the float chambers item 27 O-RING 22U-14561-00-00 See http://www.boats.net/parts/search/Yamaha/Motorcycle/1987/XVZ13DT/CARBURETOR/parts.html If they are missing or in bad order the bowl will drain.
snyper316 Posted March 16, 2017 Author #25 Posted March 16, 2017 I didn't replace that oring Living life one curve after the other. Vroom scooting, thru the countryside.
