I rode my 1996 WXC 610 for the first time this weekend. Ran like a perfect for the first 30 miles of tight single track trail, then it started repeatedly dying.
It was acting like it was running out of gas. As I sat there attempting to re-start it, I could hear a slight hissing sound coming from the front of the fuel tank area - I assumed it was over heating, and just the radiator cap venting excess pressure. Let it cool off, then got it re-started.
Ran fine for 4-5 minutes, then died again. This time, there was a little fuel around the gas cap. So I unscrewed the gas cap and it spewed a slight mist of fuel, and vented a lot of pressure. I screwed the cap back on, and shook the bike back and forth for 5-6 seconds and it repeatedly would build up pressure - almost like it had soda pop in it, instead of gasoline.
I swapped the gas cap vent hose and valve, with the vent hose and valve off my other bike - no different - still pressure build up. I pulled the rubber piece out from the underside of the gas cap, and reinstalled, and that appeared to fix the pressure build up issue. However, I just parked the bike for the day because it was getting late and did not want to be stranded miles into the woods and it turn dark on me.
Has anyone else experienced such a thing? The gas was purchased 5 hours earlier in the day (10% ethanol). Does ethanol fuel have carbonation type properties? I normally run 100% gas, but none was available.
