I have a 99 sc500 that recently started leaking gas excessively out of the drain tube off the carb. I cannot figure out why. The only thing I've done lately is change my inline fuel filter. Any help would be helpful..

 

My 96 Xplorer does the same thing. I only notice it what I go out in the garage and get a smell of gas and look under the machine seeing a "gas stain". I assume it had something to do with pressure building up so I loosen the cap.

I'm not sure what causes it though as I too have recently changed my fuel filter.

 

You may want to check your oil to see if it smells of gas. It sounds to me as if the needle and seat in the carb are either worn or there is something stuck in the seat keeping it open. I always shut the gas off after riding just to be safe. Had a Suzuki dirt bike years ago that actually filled the crankcase with gas overnight. If you do your own maintanance you should be able to check the float in the carb but make sure you have a manual handy so you know where it is supposed to be set. Good luck.

 

Check the carb float valve & seat. Turn the gas off when you are done riding until you do to minimize the problem until you get it fixed.

 

When I had the shop install my set of reids they had to put in a new main/needle (something in the carb anyway). The leaking started after that. I will talk to the guys in the shop. Thanks

 

I have a 2 week old T-Boss that does it a little and my brother's week old T-Blazer does it as well only more.
