I rode to work this morning, rain and snow, had an issue with the engine. It lost power but still ran, exact same problem in the exact same place on the freeway the last time I rode in the rain. I felt the power loss, tried giving it more thottle and it would burble. It would idle fine but definatly a loss of power. Pulled off the freeway, let it idle and rev'd it a little to clear it out, no problems after that. My thoughts. I put an evap canister on it but it was missing the front (rubber piece) elbow connection. Maybe water is getting into the evap canister and routing up into the throttle body? I just filled the gas tank up that morning as well, possible bad fuel? Seems to coincidental but I just filled up the gas tank the day before on the last time this happend. Any ideas? | ||

It could be a bad spark plug wire. Mine get rubbed through where it rubs on the inside frame rail. If it starts acting up in the rain, I know I need to replace the wires. Whats funny about your issue though, is that it happened at the same place on the highway. Maybe that evap canister is the culprit. Check the wires. If they're o.k. then it most likely has something to do with that canister. | ||

+1 on the plug wires. A while back, I had a loss of power during a HEAVY downpour. Limped home after letting the Uly "dry out" on the side of the road. That weekend, I replaced the plugs and wires. This time I made sure the spark plug boots covered the plug (~1/16th inch from the flats). Also, the rear wire had a small crack but the resistance was in spec. Anyway, no more problems since. It is odd your troubles occurred in the same place. Your ideas on the evap canister seem logical. However, years ago when I had bad gas or watered gas, my bike simply died and failed to start/idle/run at all a very short distance from the offending gas station. BTW, I only found a couple of tablespoons of water in the drained gas - it doesn't take much! Hope you find the culprit. Good luck! | ||

Thanks, I give the plug wires a gander. | ||

I had a similar issue with mine a year ago or so. When it would rain I would get to the same distance from my shop and it would cut off. I fire it back up, it would run for about five miles and cut off. This was only when raining or on wet roads. Same distance every time. A lot of searching found the wires to the cam position sensor were tight across the edge of plastic chin faring and the insulation was rubbed through. It was touching plastic so the only time it would fail was when water conducted the electricity across the wires. | ||

I believe your problem is due to filling the tank with gas. Overfilling or filling when the bike is hot will cause the fuel to expand enough to come out the vent and into the charcoal cannister. I've had this happen more than once. My cure has been to fill and go and to never fill above the baffle under the cap. On a hot bike even filling to just the baffle you will see the fuel expand enough to run out the vent when the fuel warms up just sitting there in the hot sun. Symptoms just as you explain will occur until the charcoal cannister clears then all is good. BC Steve |
