fuel leak

[Rodney]

After opening the drain screws on the 4 carbs to confirm I had clean gas in there I now have a fuel leak. I took 2 of the drain screws out out and see that there is not a rubber "O ring" in there. When I look at my shop manual it shows a small "O ring" with a part # 92055-1053. I purchased the bike 2 months ago after it sat unused for two years. The previous owner told me he had the carburators overhauled once. Question is do I need the "O rings" or what can I do to stop the leak? There is only 22,000 kilometers (13,000 miles) on the bike. It is a 2001 model.

I would make sure that I had them on there. Any hardware store of auto parts store should be able to help you out there if you don't buy them from a Kawasaki dealer. I would also replace all of them while I was at it .

I believe that these are the correct dimensions

Outer Diameter: Approximately 6.5mm
Inner Diameter: Approximately 3.5mm

Are you missing 1 O ring or this same one on all 4 carbs? The blow apart doesn't show exactly where this O ring sits but if it is missing you will need it. Make sure all the gaskets on all the float bowls are good as well. I have had leaks on another old bike where they dried out from sitting with no fuel in the bowls.

I am not sure if the new "O" rings are the correct size. What i have is too big to install on the drain screw. However I did poke it into the hole where the drain screw sits but am not sure if it is going to work.

FUEL LEAK FIXED I got "O rings" that were 4 mm inside diameter and 6 mm outside diameter thus they are 1mm thick. Picked them up at a small engine shop, installed them and problem solved. the shop called them a "4 x 1, O ring"
