I haven't ridden my 06' Banshee in many years, probably 6-7, and was planning on selling it soon. I broke my T-12 vertebrae on it back in 2013 and don't have the body to keep riding hard anymore. Strangely, starting the day I crashed, one of the overflows began to leak when the fuel was on. I took the carburetor apart and messed around with the floats a little bit, but it didn't solve anything.
Fast forward to this year, I decided to try to square it away so it would be worth decent money. My brother in law took apart the carbs again and cleaned them out (not entirely sure of his level of expertise though he has ridden bikes for a long time) and not only is it still leaking, but it began to run very poorly this year, assumedly from something being clogged up with old fuel. Now both carbs leak, and it idles very rough. When you give it some throttle, it just sputters and can't get into powerband.
Does anybody have a good idea of what I should look at first in this situation? I'd prefer to not have to spend a lot of money to repair it just to sell it, but it would probably be worth at least 500 more if I did fix it. Like I said, the carbs have been cleaned out, as well as the reed valves, and I replaced the plugs. Pretty positive it would be fuel related, but it doesn't have a fuel filter to get clogged, and I'm not sure where else it would be getting choked out other than at the jets. Thanks in advance to anybody who has any insight!
