I bought my first bike about a month ago its a 2000 road star 1600 and i absolutely love it! The other day me and a buddy went on a short ride about 80 miles. When we got back i pulled my bike into the garage and shut it off. As we stood there talking for a minute we heard a spitting sound and then a sizzle coming from my bike. As i was looking it over it did it again and thats when i saw gas spit out of a 90 degree brass elbow on the side bottom of my carb. It hit the motor and made a sizzling noise. Anyone have this problem? Is it normal? Also when we left i had right at about a half a tank of gas and when we got back the gas light was about to come on. Upon further inspection i notice a spatter of some burned or chared substance on the front of the side cover and on the top of the motor casing right below that. Anyone have any ideas?
Thats a classic carb puke issue that generally happens when carb heat soaks for just a min or so post hot shutdown because the fuel is litterally being boiled out of the carbs float bowl which isnt an improper float lvl issue.
It's worse with winter blend fuel that boils at lower temp then summer blend fuel does.
My 06 silverado used to puke fuel in 55-60 deg temps which i fixed & now is good to 98 deg F which at my age is the hottest temp i can handle riding in anymore!!!/LOL!!!
I corrected 2 other R*s that were puking fuel with the same fix i came up with which cost approx $20 for supplies & 2-2.5 hrs of very easy low tech work.
The 1st time my bike puked fuel it spit fuel out all on the lower portion of the rear cyl/pushrod tube etc sizziling and making a lot of white smoke showing the fuel was extreemly close to igniting with a full tank of 5 gals of fuel !
That was my 1st experience with the carb puke issues i later found many R*'s had which Yamaha never really addressed which was a crime IMHO
I also read about some R*'s actually catching fire when puking fuel on a hot motor & exhaust pipe or when the motor backfires thru the carb when trying to fire up the motor at the same time the carb starts puking fuel so you need to address that from a safety point of view IMHO.
I sent/PM'd you info on corrrecting it which includes 1st relocating the hose the carb pukes fuel from to exit below the bikes motor & frame to keep fuel off the motor & pipes if it ever puked fuel again from the carbs float chamber vent tube so it ends up on the ground and not a hot motor.
