Float bowls GL1500

The 88 Goldwing is still running rough. It seems to be getting worse. It was recommended that I drain the float bowls but I cannot find the drain. I've alread done the Seafoam, all of the filters, can can't find any vacume leaks. I'll be syncing the carbs as soon as I get some gauges.



Anyone know how to drain the float bowls while the carbs are still on the bike?

If they're anything remotely like my 83, there should be a screw at the bottom of the bowl that drains them.

I just rebuilt the carbs on my 88. In the attached photo, the drain screws are the 2 screws on the bowl just over the black drain hoses. According to the Honda manual, you can access the mixture screws ( close to the drains ) with a long screwdriver from the front of the bike ( over the radiator).It might be possible ( yeah right!!!) to open the drains from the front too.BTW, on my 88, I couldn't even see the carbs from the front. Sorry.

Thanks RStar, I spent some time looking at it again last night and I have to agree with you. If I were to remove the front tire, the forks, and the raditors, I might be able to get at them. I'll have to wait until I pull the carbs and that won't be during riding season.

None of the above is required... :shock:

You can get them by removing the rad grille if you wish but they are accesible with a longer straight bladed screwdriver.
the drain hose goes to the right side rear of the engine.
I used a jar to collect the gas so it doesn't pee the floor..:D


A flash light is suggested to illuminate your way:blowingup::cooler:

I'm not sure, but why do you need to drain the the carbs float bowl. I dont understand by draining the fuel will make your carbs works better. To me, you can only clean the carbs bowls by taking the carb out and open the carb float bowls. I've done this my self few weeks ago, now the bike works fine and no more leaking fuel.

They idle screw caps are supposed to be glued on with red threadlocker. I heard you might be able to heat them with a soldering iron and then pry off, but remember there is GASOLINE in there - think BOOOOOOM! I would wait and take them off when you remove the carbs. Good luck! And may you keep all your eyebrow hairs!
