Carb Heater 3 Years, 11 Months ago  
My carb heater has fallen out and is gone. Is this something I need to order and get reinstalled? What will happen without it? This is on a 2004 R*.

Thanks, David

I ran both my bikes without carb heat and they work fine WT.

I am sure in a colder climat they might be a little fussier in real cold temps, but has not been a problem either in Arkansas, or Southern California. Riding temp range has been from a low of the high twenties, up to over 100 degrees.

Wotz a Carb Heater?
Asks Darkhorseman from Darwin NT Land of Oz

Why would you need to heat fuel? ... Where I live we have to scream in sideways, fill up, and ride like hell before all the petrol (gasoline in Yankanese) evaporates.

Thanks Gram,

That was what I wanted to hear. I usually start riding in the mid 30's anyway. Doesn't sound like to much of a problem.

Re:Carb Heater 3 Years, 10 Months ago  
The purpose of the carb heater is to prevent the formation of ice in the carburetor. Vaporization of fuel and expansion of the air in the carburetor causes sudden cooling of the air/fuel mixture. The combination of a lower pressure, gasoline, and moisture in the air can so cool the metal parts of the intake that the moisture adheres to the carb as ice. The ambient air temperature in a carburetor can be reduced at its venturi by as much as 70F within a fraction of a second. For the same temp, the higher the humidity the more chance of carb icing.

A slight accumulation of ice restricts the flow of air into the carburetor, causesing a drop in rpm and the engine runs rough because of an excessive rich mixture.

Thanks Doc,

I am going to see what one will cost at the dealer this afternoon. With our humidity and cooler summer temps, I could get an icing problem.

Re:Carb Heater 3 Years, 10 Months ago  
How much does one of those run? Please let me know. My bike only has 300 miles on it, and it fell off. Should that be covered under warranty?

Thanks,
Roger

You would think it was covered under warranty. All the parts for mine was $20 and change. It was the heater, ground blade and a washer.

Re:Carb Heater 3 Years, 9 Months ago  
Well, the 'stealer' put a new one on under warranty, because they rejetted the carb when I bought the bike. The bikes running way rich, but they wouldn't touch the carb jetting because they said my fuel pump relocate voided any warranty for the carb, valves, and "a bunch of other stuff." Can you believe they said that to me? I'm no mechanic, but I know enough about machines to know they are full of BS!! If anything, the fuel pump relocate might decrease pressure, due to the extended line. SO, I'm jetting myself! With the tech tips on this forum, I'm conficent I can do it.
