Sub air filter

Postby tonymac » Sun Jan 13, 2013 7:12 pm



Hi folks. I recently bought a '92 goldwing. First one. 42000 miles on the clock. I've just removed a very crumbly sub air filter. Still intact except for a small circular centre piece that was missing. The bits from the centre of the filter have obviously gone somewhere. How worried should I be? The bike goes OK although could do with a tune-up. Needs extended use of choke first thing in the morning.

Yep that's the problem not much you can do for now..could try to vacuum the bits out if you've got a vacuum attach small hose to the end and stick in the opening..can hurt..if you put some panty hose over the end stuck in the vacuum you can see it you caught anything.

CAN'T HURT... :lol:

By the way there are two sub filters one on the left side for cruise control and one on the right for ???. Any good idea to change both..a pain to get to but still good idea.

Thanks, I'll try the vacuum. Any idea what problems can develop with these bits of filter
In the solenoids?

The filter on the right side goes to the solenoids as mentioned, and from there into the carbs. Bits of filter in the solenoids could keep them from closing completely, leading to a slightly lean mixture. Of course it's not great to have bits of filter going through the engine either, but they would likely be burned up quickly and sent out the exhaust.

Thanks for the advice and information. I tried the vacuum and retrieved a small
amount of debris. I kept going and managed to suck petrol through the solenoids!
Have I stuffed them completely?? I''ve got the driveshaft off and waiting for moly
paste to arrive so I won't get it back together until next week.
