Why in the blasted heck is it so hard to find the O-rings for our oil filter?!
I've re-used mine for quite a while and wanted to replace them at the next oil change. Here in the northern suburbs of Denver it's hard to find a motorcycle parts shop any longer. Buying online, the shipping costs more than the parts.
$9 - $15 shipping for $3 worth of parts.

Someone posted a #114 at O'Reilly's will fit for the small one. Anyone confirm?

And looking online and entering the 09280-72001 for the large O-ring and either 09280-16005 or 09280-15007 for the small one comes back with "does not fit your 2008 Suzuki S40 Boulevard" on Partzilla. Pretty sure those are the correct parts.

Also, what happened to the "site:" search operator on browsers? Did AI just kill that off? Sheesh.
