I recently moved my bike 6.5 hours on its side in the back of my pick up truck. When I started it a couple of days later Gas and all of the oil came out of the vent tube out the air box. I fugured it was just from it laying on its side. Then I changed the oil, oil filter, and air filter. Then when I turned it over it started for a second then backfired and died. I kept on turning it over and gas and oil came out of the same spot. I took off my carbs and cleaned them and tested to see if they were leaking and they weren't and my petcock is working fine but I am afraid to spend another $40 on oil and an air filter. would anyone have any other suggestions? or am I ready to try it again?

I have an '82 Maxim 650. Runs so-so and needs a new carb, which I have but didn't get put on yet. It just started losing a lot of oil out of the air cleaner box, through the hole in the bottom. Oil gets soaked into the air filter as well. I have no clue what would cause this or how to fix it. I am wondering if it is even worth fixing due to the age and value of the motorcyle. Anyone on here have any ideas?

Engine flush - should get rid of the blocked oil passages and keep oil from spurting all over the place... The gas coming from the carbs means you need to overhaul the carbs (seals are leaking or the plunger isn't seating anymore cause its worn or the float height needs to be set). If it won't turn over and the oil light is on (and you have a good battery, good starter relay, and good starter motor) means you have a seized engine - time to get a new bike or overhaul your engine (if you can find the parts)... The line that supposedly came from the airbox that came off when Andy dropped his bike is the fuel line - it only looks like it came from the airbox because the airbox is connected to the carbs, it actually goes to the carbs... wish you luck getting your bikes fixed guys...
