It purrrrs, now onto the radiator.

Postby B0b88 » Tue Mar 05, 2013 12:13 pm



After about 6 carb removals and much research I've made my Goldwing purr at 950 rpm :) I did a bench sync and was able (with a 90 degree Philips) to change out the rubber nipple things without having to take the carbs apart from each other. Also I've set the idle air adjustment screws to two revolutions out, is that a good place to start from?

About the Radiator now :)

Running the bike at idle for sometime last night I noticed green coolant under the carbs so obviously I have an oilring or gasket needing to be replaced on the pipe under the carbs. Should change them I'm all I'm thinking. But the problem is, I've yet to see the fan come on... And yet to see the gauge on my display read anything but cold.. I know it isn't the 7 volt regulator (yet anyways lol) because my fuel gauge works just fine... I'm going to test my fan with a 12 volt battery tonight, I was reading through some posts and I didn't quite understand how you check the thermostat by boiling water... ANY suggestions will be much appreciated :) thanks for lookin!

The fan can be tested right on the bike by unplugging the 2 conductor plug on the thermo switch and shorting one wire to ground with the key on.The other wire(green) is ground,so you could also just short the 2 together.
While your there,leave the key on and use a test light(grounded) and probe the temperature sensor wire.There's just one on it.With a test lamp attached,the temp gauge should swing up.Don't hold it there long,just enough to see if the needle moves.

Testing the sensor in water....The thermo sensor is electrically attached to the bike... but put in a container of water then heated...as the temp rises,so should the meter(needle).
It's a pain to rig this up....and only for those who want to know exactly what temp is showing on the needle.

Also...If there is very low coolant,the temp sensor and switch will not work properly either.
They are supposed to be in contact with the coolant so be certain the system if purged of air and full.

As far as the mixture adjustments....well it's a good a place as any to start....You'll know if they need adjustments...look at the plugs after a few hundred miles and compare to the "how to read your spark plug" posting.
Obviously if the engine is not preforming right....popping,running hot,or the such...you may need to do the "idle down" adjustment on the idle mix valves.Yuck.
There is one fellow,while he had his carbs out,fixed a "T" handle thingy to his needle jet screws so he could adjust them easily....pretty cool idea too.

Hey congrats Bob..You got it going that's great...and she purrs you say... What's up with the radiator...? If you want to sell the 81 carbs for cheap I am interested,,,I can get those jets out ..Then maybe find some other slow jets to install and it will be good again..

so that means the price might be pretty cheap? I understand if you wish to keep them for parts...
