I can't believe I read all 4 pages of this post. I think "I'm" gonna puke! I have only had 1 occasion that I experienced puking which was after I cleaned the carbon build up. So, I'm not going to touch anything unless it catches fire at a gas station (like on that other post). In which case, I'm going to get an 08 or newer as a replacement. No more puking, jetting, or having to read long posts to see if they apply to me. LOL. I can only pray that the gas station it happens at hasn't checked the levels in their extinguishers in a year or so. Sounds like we should all sign a petition to make yamaha fix this concern since it obviously happens to all of us with 1600's and 1700's. Maybe yamaha will buy us all larger float bowls, heat shielding, 2.5mm float valves, high flow fuel filters, shielded fuel line and give us 50 bucks for our old fuel pumps.
