Resources for Discontinued Parts?

[micro1331]

Looking for any suggestions/tips on finding discontinued OEM parts. I've had some luck randomly scouring the internet for places to buy certain parts from but am striking out on some. Being located in the US, my primary resource aside from big name retailers (bikebandit, partzilla, etc) has been eBay with varying levels of success. I'm open to NOS, or used even if not in good condition, just trying to build up my resource library.

The current items I'm struggling to find are:

#4 Outlet LH :: 13881-44100
#5 Outlet RH :: 13882-44100
#7 Cap Air Cleaner :: 13740-44100

I've called the Parts dept. at South Sound Honda/Suzuki up in Olympia,WA.(hondabike.com)and they have been very helpful if I had a part#.
I would keep looking at Ebay and small 'off the grid' Japanese bike yards/collectors also;possibly 'offerup',etc.?
key-word 'air filter box'.

Just search this Forum. There are tons of links to resources/sellers.

Ask your dealer to run a locate on the discontinued part. You may find one sitting on another dealer's shelf somewhere.
