1981 Suzuki GS 650G

[Guest]

Hello everyone, I am new to owning motorcycles and this '81 is my first bike and I absolutely love it. So my question is in regards to what I believe is a carb issue. I had the carbs rebuilt in October 2013 and when I got her back it ran beautifully. I did not ride it as I knew I would be travelling for business so I winterized her with Sta-bil. So last weekend I threw off the cover, charged the battery and got ready to start her up. When I did, fuel shot out of the tailpipe about 10 feet.
What's wrong with her? Stuck floats? Leaky fuel valve? Any advice would be much appreciated as I'd like to get my baby running again ASAP.

Cheers and happy riding,

KM

Probably both. Unless you left the petcock valve in the prime position, I'm betting that your petcock is leaking. If you had fuel come shooting out the tail pipe then you also have at least one leaking float valve.

You need to drain the oil before you attempt any more starting as it's very likely that your oil is contaminated with fuel. Replace the filter as well.

You'll probably have to pull the carbs and identify which carbs are leaking and either adjust the float level and/or replace the valve.

Check your oil. Check your petcock.
Next time you winterize it, disconnect the fuel line.

No fun on this model, so first check petcock for correct operation- maybe you left it in "PR" spot by error last fall and will just have to change oil- otherwise carb fun awaits! As tkent02 said, best to disconnect fuel line if bike is going to be idle for long time.
