Flooding after hard rides only? 2 Years, 2 Months ago  
04 RS 1700... So I've noticed that ONLY after riding 70+mph for several miles like on the interstate then I pull over somewhere and shut it off and let it sit for 20-30min it will have flooded. When I sit on the bike and tilt it off the kickstand, gas will pour out from carb or somewhere on right side and when I go to crank it over it will take waay too long to crank and when it finally does fire up, it will spit fuel from the exhaust. It only does this after hard riding. What could this be?

Search "carb puke" on the forum search - hundreds of pages lol. Engine heat is cooking, expanding / evaporating fuel from bowl and feed line. Many ways to get around it. Everything from going pumpless to as simple as shutting off gas just before you stop. . . . . .

Yep, carb puke. Aggravated by ethanol. The fuel between the pump and the needle and seat, expands from the heat when the bike stops moving, and forces past the needle and seat, and floods the bowl. Shut the fuel off at the Petcock about 30 sec before turning the key off, and that will solve it, or, lose the fuel pump.

call me different, but it may be your jetting /air filter/exhaust/float level combination running to lean and making it run too hot, which will get the carb real hot and puke, AND , tell us when was the last time the carb was "gone over", or it could be dirt in your needle and seat inlet valve in the carb, or it could be float level.

when the bike is hot on a 70 degree day, you should be able to touch the barrels without burning your palm of your hand for a mili-second, not a real hi tech deal here.

here is a question for all

WHEN IS THE LAST TIME YOU DRAINED YOUR FUEL TANK AND LET IT DRY IN THE SUN.?
