Ok whenever my girl is on the back of my bike when we are done riding her clothes reak of gasoline.. i have stock exhaust its not gutted or modified in any way..

any suggestions will a aftermarket pipe help the problem or is it something else..

 

I have a 2 brothers exhaust slip-on. I did notice once she kinda smelled like gas, but most the time she doesnt...

 

If your exhaust reaks of gasoline, it means there's an excessive amount of gasoline in it.

Your bike is running rich, and you need to troubleshoot that. An aftermarket exhaust is just going to increase airflow, and subsequently spit out MORE gas smell.

 

if you stand behind the bike it smells like normal exhuast fumes.. i am new to bikes so what could cause a bike to run rich.

 

On an injected bike, generally poor airflow, or a poorly mapped power commander, if you have one. I'm not too great with injected bikes. When's the last time you changed your air filter?

 

check all your breather tubes under the tank, might have a pinched line or check your gascap. sounds dumb but you never kno.

 

. . . . that would cause a LACK of fuel.

 

yea i will check the filter cause i dont have a power commander..
i will let you know if that fixes the problem any other suggestions and thanks for the advice

 

Sounds like you're running rich. I have a full exhaust and PCIII on their map, which i've heard runs rich for safety reasons. My clothes ALL smell like fuel, i've gotta get a tune. If I were you I would get a PCIII, maybe a slip-on and go get it tuned. Should fix your problem. I want to get mine tuned but I don't have the cash right now. Hopefully it will be done b4 next season. Good luck.

 

Ehh. . . most everything else is a weird, rare (but possible) situation. You could have a broken injector that's throwing too much fuel, or a bad ECU (though other problems usualky exist to give you a clue)
