I pulled the bike tank off and air cleaners for some work and found a burnt up small rubber paddle wired into the harness that was used for carb icing I think-is it a heater or what ? anyhow it is toast-rubber melted and metal blackened inside the thing. No performance problems related I dont't think.? Does it hurt to disconnect and take it off? I didi , bu thave niot ridden bike yet. I moved it when I put the NARK on and I it got into the metal and shorted out. What to do? Help.

W650s in several countries came with carb heaters. The bikes were equipped with Keihin dual carbs almost like ours .... maybe a mm or so smaller intakes. The USA W650 did not come with heaters. After 52000 miles and 7 years of ownership, I never noticed a problem because the bike didn't have heaters.

The exception ... the W650 did begin running on one cylinder maybe 2-3 times over the time I owned her, which may have been caused by carb icing .... don't know. I would pull over to the side of the road, turn her off for a minute or so, then off we went without a hitch.

I don't think you'll miss the heaters (IMO). Unless you subscribe to the viewpoint that carb heaters are there to warm up the carbs for cold weather starts.

I believe what you are referring to is the temperature (air) sensor that was connected to the side of the stock airbox. When the airbox is removed, one has to do something with that little "rubber paddle thingy"--I taped mine to some wires behind the carbs if my memory is correct. I doubt if removal will affect much--other than the carb heaters may not function. I just looked at the service manual and the item is called a "carburettor heating system temperature switch" and is clipped to the right side of the airbox. "Below approximately 10 degrees celius, the temperature switch supplies electrical current to the heating element on each carburettor."

Again, it looks like all you will miss will be carb heat, and some have run without it for a long time.

Obviously folks fitting the HSR's and other aftermarket carbs won't be using the heaters and I have heard of no issues with them. Heck, I would run with it discon and if after a good bit of colder weather riding if no problems then you can snip the wires to your heaters! I have heard the educated argument for them but unless it is an issue specifically with these carbs I am leary cause I have never had a bike with heaters and never iced up. Is that the opposite of vapor lock?

Here in the Southern US, I definitely don't require the heaters. However, I can vouch for the fact that they work. I burned my finger on one while adjusting my idle mixture...ouch!

I guess this isthe new PM?? I have never had a carb ice up in my 45 yrs of ridinf!! I think its like the old auto polution control- preheat the air intake. Hell Triumph used the old air injection of the 70's I DXed mine on the 1st day & have never hada problem. As you said add on carbs dont have them either!

If you go to this thread and read through it, you'll see why it's important to have carb heaters

Badrufus - Cannot open the carb heater thread. Could you summarize what the threads says about carb heaters?

Here's what I know. Kaw ran them on some of the W650s with Keihin CVKs very much like ours. My USA version did not have heaters. The Brit version did. W's sold in some other countries did.

Seemed like someone stuck their finger into the sky, determined the humidity, and made a decision on which countries needed heaters and which ones didn't. I don't think Kaw made their decision based on average temperatures, since we have some very cold areas in the USA, most likely colder than the UK.

Also, I don't recall reading any place where Kaw claimed the heaters were there to assist in cold starting. My W650 always fired right up, actually better than my T100, in extremely cold weather. Without heaters.

Now, if the case for heaters is to prevent carb icing under certain temp and humidity conditions, and if the Keihins are prone to icing up while riding, then having operational heaters make sense.
