I remember, probably 20 years ago, Bike and I were going somewhere and, as usual back then, pushing it across Nevada. During the longer stretches of open road, Bike would act like it was having issues. Hard to pin down, but like it was running low on power. No symptoms in Oregon or Washington with their lower speed limits and shorter distances between towns.

Same symptoms though, any time we got to roll for any length of time.

It finally occurred to me I was running out of fuel so I replaced the filter and all was well. When I opened up that filter, it was mush inside. It was one of the Emgo OEM look alike filters and, the last one I ever bought.

I just replaced my spark plugs, fuel filter, and air filter at 34,000 miles. The spark plugs were at the high end of the gap limit, so they were ready. The air filter was dirty, but not that bad. The fuel filter was clean, but the plastic case was dark and getting brittle from the ethanol gas.

spark plugs have come a long way since the 80's. copper plug you use to be lucky to get 30k miles out of them. platinum was a game changer @ 60k. and now with iridium plugs they advertise 100k/lifetime. i use iridium plugs but change them out @ 60k. the reason being that as spark plug gap increases with wear / mileage it causes an increase in resistance of the ignition circuit. this makes both your coil work harder to jump the gap, and with the increase in power required to do this also accelerates spark plug wires wearing out sooner do to being cooked more/faster.


air filters are environment related. if you are in a dusty area or ride dirt roads 10-15k miles. otherwise non dusty conditions i check at 30k and most will show signs of moderate contamination. 45k they need it in my opinion. ymmv.

I have to respectfully disagree that the more expensive plugs are any better than what comes in the bike.

I have a friend who put over 200K on his original plugs (GL1500) and when one of the new plugs failed, he replaced it with an original. That plug was in the bike when he sold it with with over 300K on it.

fuel filter and other things...

My fuel filter has 60-80k miles on it, I suppose I should change it out... (ya think?!) I noticed after doing an alt conversion on my 86 aspy that mileage dropped from my usual 48-51 mpg to low 40's and I thought maybe the extra effort of turning a tight alt belt might have been the cause, but then also thought about plugs, wires and the filter- all original when I bought the bike at 21K miles. I use MMO with every 3-5 tanks and also use it as storage stabilizer over winter- always starts up within 2 seconds of cranking after sitting all winter and runs great, so I might have been lucky that the MMO was keeping the filter relatively clean as well...

So I'm thinking it's time to replace all- plugs, wires, fuel and air filter- this spring. I did have the plugs out to check them after my 4,500 mile trip in August 2018 and they still looked almost new. Your thoughts? And where to purchase these? not a fan of aftermarket unless someone recommends a source...

Thanks in advance!

I would avoid Emgo fuel filter. Mine disintegrated in the Utah desert. I only use OEM now on the GL1500.

OEMs for the '87 GL12 are "No Longer Available" according to Western Honda.

Can anybody confirm the part number for that unit? I think it's the same as the GL15.

The filter fits many Honda bikes up to 2007. 16900-MG8-003 The number is the same for all Wings.

Thanks Val. That matches the number I found on eBay. It is the same as the GL15. Why would Western say it's not available? Lately they're acting like they want to rid themselves of all us irritating old parts customers.

And sorry Guillaume, your thread is kind of getting hijacked. Personally I think you should change the filter. 25K sounds like a good number. Write the date and mileage on the new filter, if you don't keep those numbers in a log.

You're welcome. That would be odd why they say it's unavailable. Buy a few before they become obsolete.
