Ok I have an issue, I have a 97 cbr street fighter style my first bike, n for the second time now I've put gas in it and the first time it was dripping out of tho bottom of the tank, there wasn't a hose hooked to it, so we connected that, then this morning I put gas in and it started dripping out of this black canister on the under carriage of my bike! What is that canister and what could possibly be the problem?

 

Can you post a pic?

 

Ok I found out its my evap canister, and from what someone told me its from me over filling my tank! Idk all this is confusing! I'm gonna have to get a manual!
