Hello from a new Ninja 250 owner

Hello all! I just purchased a 1999 Kawasaki Ninja 250 for what I thought was a good price (650). The PO said that he got it running after it being stored for a few years. He said it would idle fine but if you hit the throttle it would die. So I figured it would only take a tune up and a carb cleaning. First thing I did was clean the tank and petcock. That should have been the warning for what was to come. The petcock was frozen and couldn't be turned to either on or reserve. The strainers at the top of the petcock straws were rotted away and probably what clogged and froze up the petcock. So I repaired the petcock back to usable condition but I will probably be replacing it. So on to the carburetors. I removed the carbs with no issues but when I removed the intake boots I noticed that one was installed backwards. I started disassembly of the carbs and inside the diaphragm housing there were some sort of leaves under the diaphragm. The inside of the bowl was trashed! I've cleaned some really dirty carbs before but this one takes the cake! The floats were frozen to the hinge pin, the float needles were stuck in place, fuel adjustment screw o-rings were missing and the collar that belongs under the emulsion tube was installed from the top. When I changed the oil I didn't know what to think when I saw 2 stroke oil drain from the pan!! Then when I removed the oil filter I noticed that the spring and washer was missing. The bike has 25,000 miles and will need tires, carb rebuild kits, oil filter spring and washer, and other odds and ends. My question is- will it be worth it to get this bike back to a safe and well running condition? What other things should be addressed to prolong the life of the engine.

Hello Brandon, welcome to the board. If I had a carb problem like that I'd send them to our @ducatiman for a complete rebuild to new spec.

What makes you think the engine oil was 2-stroke oil?

I'm not 100% sure about the oil but it was a greenish blue color and smelled like 2 stroke oil. It was also very clean the oil filter almost looked new. My theory is that the PO got the bike for cheap or free and it was his first bike. He probably tried to clean carbs by only spraying the inside of the bowl and not completely disassemble and clean. He probably thought that 2 stroke oil is used for all motorcycles. And the oil filter spring and washer might have either been missing to begin with or discarded with the old filter when it was changed. I think he used starting fluid to see if it would run and then told me that it would idle but die out with throttle. I thought it looked very well taken care of when I first checked it out.
