Went for a short ride Saturday,and when we stopped for about 10 minutes the bike was hard to start, I noticed a gas smell when I got on the bike. Took three or four times to get it started, had to really open the throttle to start it. We had only gone about 80 miles. Then we rode about 25 more miles then stopped for lunch, same problem, smelled gas when I got on the bike, and won't start right up. Also noticed it was running kind of rough no matter what rpm's were. Idea's? I am in no way a mechanic, so will have to take it to the dealer for repair. Thanks | ||

I had the same problem until I removed my charcoal cannister. Do you have a charcoal cannister? If it gets clogged all kinds of problems. An overfilled tank will eventually kill a charcoal cannister. charcoal cannisters are supposed to filter vapors not raw gas. I have eventually learned not to overfill the gas tank. | ||

Not sure if I have a charcoal cannister, the bike is stock. One thing I forgot to say was that I only rode about 130 miles and when I got home the fuel light came on, which means I was only getting about 26 mph. I was not pushing the bike at all that day. I normally get over 175 miles to a tank. | ||

bikes delivered to California have a charcoal canister - it the big black round cylinder under the seat near the battery...the frame is the gas tank - the engine heats the frame - the liquid expands (fuel/gas)it has to go somewhere - the trick is NOT to fill up on your way home - i have to plan to get gas before I go riding - be thankful - some of the guys (in other states) install the canister as the bike will urinate raw gas on to the garage floor without it. | ||

Based on your profile you probably have a CA bike which comes with the canister. Canisters were supposed to help with the gas smell coming from the overflow tube, but perhaps you have a break in that closed loop or something. A vacuum leak like that would explain the rough running and bad gas mileage but I would think you would also see the AFV drift out of range and set a check engine light. I'd start by checking over all the lines to and from the canister and having a look at your AFV values in diag mode. | ||

What happens is this: The cannister vents into the front cylinder just below the throttle body. The gas vapor from the expanding hot fuel in the frame flows through the carbon can where it loses its smell. Then it goes into the intact tract and basically makes the front cylinder too rich to fire. When you open the throttle to help the problem 2 things happen: 1. the volume of air available for this vapor to vent grows greatly as it now includes the entire airbox and atmosphere 2. when you run the starter this rich mix is pumped quickly out the exhaust This symptom is a fact of life with a carbon cannister on the 1125. Yet another band-aid to a real problem from the factory. ac | ||

Thanks for the info, I will check it out and see if that helps. |
