I smelled gas from my bike (cbr 600rr - 05) and took it into the\ndealer for inspection. They confirmed that the gas I smelled is coming\nfrom my vent hose. The service guy said that it's due to the fuel\nvapors and completely ok. But no matter how much gas is in the tank, I\nsmell the gas vapors from the overflow hose. Further, some guey residue\nthat smells like gas is building up (it is gas)at the end of the\noverflow hose. Is that normal? i put a flash light to the end of the\nhose, and I actually see the vapors. There are a couple of drops of\ngasoline that dripped from the vent hose too. is there a way to prevent\nso much vapor coming out?? The bike runs fine though and only vents\nstronger gas smells after long rides. Is that normal? bike has a\nlittle over 1,100 miles.
