Hey everyone, I have a question and couldnt find it while searching here. I bought a used 03 rx and i cleaned the carbs today and noticed that the brass sensors under the carbs that plugs into the wiring, one was broke and one was completly missing and just the wire hanging there. I rode it last year and didnt have any problems. The one thats missing looks like it has been missing for a long time before I bought it.
Are these for heating the carbs? and it looks like you have to buy the whole harness that plugs into them because the little spring and wiring connection looks like its pressed in the brass part.
As always any help would be great!

You are looking at the Carb Heaters. What you are saying one is broke off and one is missing, I assume you are talking about the connector versus the heater.
Maybe the dealer has some access to get you the connectors. You may have to ask them to ask Yamaha. Occasionally they surprise me. Or, ... If you can find and old harness, you can cut the wire up a couple inches from the connector, soldier & tape the wires. Maybe some heat-shrink tube could be used.
To find an old harness, try asking for one in the Classifieds forum. I would bet that there are several folks around with an old harness laying around, that they would part with for shipping cost.

Thanks for the help. One heater was completely gone and just a wire and the other on the wire connector was snapped off and I am assuming I rode all last winter that way! Never had any issues and we rode the black river in Port huron a couple of nights and it was -10 below one night.
Yeah, I didn't see any way or replacing just what was broke on these, so I ended up buying a new assy from Port Yamaha. I think the assy was around $15. So, if you don't have any luck finding some used stuff and repairing yours, they aren't too bad just to buy new either. Good luck!!!
Thanks guys! I ended up going and ordering it all new and it was only 30 bucks for harness and extra heater,thanks again!

The electric carb heaters are only useful during the initial warmup period -- helps keep the carbs from icing up (carb throat = venturi = high speed air = low pressure = low temperature = ice). If you are able to get it past the initial warmup (i.e. until light stops blinking and the idle drops to normal), then the engine COOLANT will keep the carbs much warmer than the little electric heaters ever could. The electric heaters actually shut off way before the engine is completely heated up.
In other words, they make startup a little more reliable when it is *really* cold out, and then they shut off. If startup isn't a problem for you, then they really don't matter.
