Hi all! Just wanted to let everyone know that I'm still riding with my knees in the wind. Have a little update for you all with the Goldwing.
I found another problem and might explain the reason why the older plugs fouled so easily. It appears the left carburetor float might be failing at times. I noticed that when I fill the bike up to the max (fuel), and park the bike, I can smell fuel leaking down into the intake manifold. This morning, when I started the bike, a ton of smoke came out of the exhaust as though a lot of fuel drained into the intake manifold over night. I know it is the right side. But after driving it for a while and the fuel level drops some, the floats work just fine (as far as I can tell). But this morning you could smell the fuel. Right now there is no fuel smell parked.
If you recall, I originally set the floats at 7mm last summer when I did a partial rebuild of the carbs (cleaning out the jets). Now that I have the kit, I'm going to rebuild the entire thing and soak it in carb cleaner over night, and then blow all the holes and ports out with an air hose. Then I will replace all the seals, jets, and if needed the slide boots. And I will set the floats at 8mm since that is what the book says, although the book also says 7mm. Anyone know which is the correct limit?
I suspect the floats being set at 7mm might be allowing too much fuel into the intake (running rich). I might also have the air-mixture screws set to far out (3.5 turns). I'm going to do it right this time, turn the screws all of the way, and slowly back them out until I see an RPM increase. Even if only 1.5 turns are required, then that is where I will set them. I believe the manual recommends setting them at 2.5 turns initially and adjusting accordingly, in or out.
I'm hopeful that rebuilding the carbs will result in proper fuel mixture, and hopefully boost my fuel economy to about 40mpg, vs. the 36mpg I'm getting now.
On a side note, I was hospitalized for a day due to heat stress. We in SC have been enduring terrible heat indexes of up to 112 (actual temp being 96). But the humidity is terrible in the south east, making the higher temps unbearable at times. What I wouldn't give to live in a dry climate, even if the temperature reached 110 degrees. I've been to the middle east about 11 times during my days in the USAF, and I can honestly say that dealing with dry heat vs. humidity is far better; humidity sucks guys!
