#974176 Doc_V (User) Platinum Boarder Posts: 6530 What happens if no carb heater? 1 Year, 8 Months ago   Yesterday, while pulling the carb on my new bike for the first time, I noticed the round post for the carb heater, where the wire attaches, was missing. I can only assume the PO or some ham fisted mechanic broke it off. So how will this effect the carbs performance until I can replace it? Does it only come into play in extreme cold weather?

You don't need it unless you live way up north and go riding in the winter   Logged     The administrator has disabled public write access. #974181 pastornj (User) Platinum Boarder Posts: 3110 Re:What happens if no carb heater? 1 Year, 8 Months ago   I removed mine from the stock carb when I had one - no problems at all - but then I do live in North Carolina. You really shouldn't have an issue without it most of the year. Maybe in the winter it is needed, but not above 40 degrees.

Well, yeah, NJ was for New Jersey when I lived there, but not any longer.   Logged     The administrator has disabled public write access. #974201 MidwestMike (User) Platinum Boarder Posts: 4779 Re:What happens if no carb heater? 1 Year, 8 Months ago   Carb icing up at 46 degrees. Jump to around 2:30 and 5:30 to get the geist of it. Has to do with velocity of the air, etc., but I still wouldn't worry about it.   Logged     Last Edit: 2016/06/18 12:28 By MidwestMike.   The administrator has disabled public write access. #974205 davej (User) Platinum Boarder Posts: 18167 Re:What happens if no carb heater? 1 Year, 8 Months ago   I don't have one on my HSR carb. IMO as long as you are not in a airplane you don't need it but I also wouldn't intentionally remove it just for sake of removing it. Also if it is gone I wouldn't replace it.   Logged     dave   The administrator has disabled public write access. #974275 Edge51 (User) 2000 Roadstar Platinum Boarder Posts: 5447 Re:What happens if no carb heater? 1 Year, 8 Months ago   Doc_V wrote: pastornj wrote: I removed mine from the stock carb when I had one - no problems at all - but then I do live in North Carolina.

Moral of the story is to run at WOT as much as possible and a carb heater is not necessary:P   Logged       The administrator has disabled public write access. #974283 Deerkiller (User) I just made this great wheelie...did you see it? Platinum Boarder Posts: 7151 Re:What happens if no carb heater? 1 Year, 8 Months ago   On a more serious note, when something goes from a given pressure to a lower pressure, the temperature drops. Like what happens with refrigerant as it passes thru the restricting device (orifice or TXV) in your home A/C system. Temperature of a typical R-410A or R-22 system can drop from 90°F to 40°F as the pressure drops (just one example). Same thing is going on in a carburetor system as far as I can tell. Atmospheric pressure gas (with moisture present...humidity) goes to a lower pressure when passing thru the carb and if that temperature drop goes below 32°F, you will start to get frost (ice) accumulation on things.   Logged       The administrator has disabled public write access.
