EZ Oil Drain Valve

[scarylarry]

Has anyone installed an EZ oil drain valve on their Valk?  What size threads is the drain plug?  Any reason not to install one?

No as it too easy to have a incident. I have Futoma valve on my truck but I modified it some to avoid a incident. I find it somewhat restrictive when draining but... Get a copper washer (14mm) to replace crappy OEM aluminum crush washer and drain like normal. No big deal.

Honda uses aluminum crush washers for the oil pan drain bolt for just about all of their vehicles. They know what they are doing.

I just don’t see the point. The Valkyrie is so easy to change oil already.

I concur.  My crush washers have only been changed every half dozen oil changes.  And I have never been able to see any crushing evident.  Because that drain bolt is just snugged, not torqued.

Introducing another (unnecessary) valve seems to be asking for trouble.

I use Fumoto valves on my current autos, but they are fairly protected from road hazards, as both oil pan drains point to the side, so the valves aren't the lowest point of the engines. They do take a bit longer to drain, but I'm never in a hurry, the way a shop may be.
Under a motorcycle, though?

When I 1st. brought the Valk home it spotted my floor and the crush washer was crushed and dripping. Now if you want to pay Honda for these cheap arse washers, your bike your choice. The copper variant is far superior material. BTW where leaks/pressure occurs on your bikes like fork lower legs,clutch lines, and brake lines are 3 places I know of that copper is used thus I'd say maintaining your oil inside the motor falls into that category also. Price of copper vs aluminum, what do you think Honda going to do? Remember these folk put cheapest arse tires (Dunlop) on most of their models. Honda is the best but still have their faults.

I’ve always used the aluminum ones. In 203,000 miles it’s never dripped a drop from that drain bolt.

77k miles and I'm still using the original aluminum washer, zero leaks.

cooper and aluminum have a large gap in nobility, they’re dissimilar. That means pairing them up will have a higher chance of leading to galvanic corrosion.
Corrosion between dissimilar metals can be enhanced by their environment. For instance, a common electrolyte, water, can jump start the corrosion process between two metals.
That’s why galvanic corrosion is kicked up a notch in moist or humid environments.

aluminum crush washers can be had for pennies. 50 washers for $6

209,000 miles, haven't replaced the crush washer yet, but I often say "I should replace that washer".
