[QUOTE="hppants, post: 1425898, member: 27852"] Again, I can't see where you have tried to eliminate the cause of the problem being a fuel venting issue from fuel at the top of the fuel tank after fill up? Things could be normal now just recently because you have 50 miles of fuel burned off and the venting issue is no longer there until you fill up again. Repeating my suggestion: You are at 50 miles on the tank - lets call that 1.25 gallons burned (more or less). Burn off 2-3 gallons more. Then go to the gas station and put ONLY about 2 gallons in it. Report back if the problem repeats itself. If it DOES NOT, then do not assume you have figured it out. Burn off 2 gallons and then put 2 gallons in it again. Confirm you can duplicate the problem under a controlled condition. Then return and fill up the bike all the way and if the problem repeats itself, THEN you know where to start digging deep to find the problem. Another thought - after you have confirmed that the problem does not duplicate on partial filling of the tank, return to the gas station and start adding a 1/4 gallon of fuel to the tank and try to get the problem to repeat itself. Keep adding a quart until it happens. Take note of that level and use that as a gage to see what's happening with the venting system at that level. Of course, if the problem repeats itself at any point with a partial fill up, then at least we have eliminated that and now have to dig further into the issues described above. The bike is inherently so dog gone reliable, we are likely going to learn that this is something very simple. A piece of crap in the tank vent - like that simple. [/QUOTE]
