xs650 flooding... praying to the carb gods

[beer9000]

awesome guide, good find... thank you.

I thought I'd test the seal with the carb on the bike before setting up to do the clear tube float test. Took off the bowls, put in the carbs, then held the floats up and turned the fuel on... still a leak directly from the same air filter, none getting past the needles..

so, that told me that excess fuel was getting in somewhere else other than through the bowls. I bypassed that other inlet in front of the carb, just ran the line from the petcock directly to the T on the carbs themselves. set the floats back down to 29mm, put the carbs back together, turned the fuel on, and NO LEAK........

I am very hesitant to feel excited.. gonna change the plugs and see if it will start without anything feeding to that extra inlet

Is that other inlet for vacuum to control the stock vacuum operated petcock on the gas tank? Stick your nose in the crankcase oil filler hole to make sure the engine oil in the sump is not fuel contaminated before starting.

does it have to do with this second inlet in front of the carbs???

TNC called it.

That is absolutely a vacuum port. Same as other XS I've worked on. Your carbs are probably fine.

Check yer oil as he advised because fuel makes lousy lubricant.

Yes Tri did......

But I thought the OP said he checked to see if the gas was flowing from that hose????? Plus I thought he had two petcocks not two hoses....... Oh well........

I guess this is where a manual and better pics would have come in handy??????????

my bad everyone. Guess I missed it when TNC said that. this is my first build and only my second bike, sorry for coming off like an asshole. Trying to only make worthwhile threads for problems that haven't been fully addresses before, but obviously I don't understand how it all works well enough yet to even correctly diagnose problems.

better pics and better explaining needed for sure. but thanks everyone for working with what you had, some really great info came out.
