If you have a Motive power bleeder for doing your brakes/clutch, you may have noticed that Motive does not offer a Honda/Acura adapter for it.
The CTA 7030 adapter gets mentioned quite a bit for solving this problem, but it's plastic and the other adapters I have for my Motive bleeder are aluminum. There are apparently two slightly different sizes of Honda MC reservoir caps, and CTA sells two plastic models (aforementioned 7030 as well as 7033) but only one aluminum model. So I went out on a bit of a limb and bought the aluminum CTA 3933 to see if it would fit, and it does!
There are a number of ways to adapt the CTA to the 5/16" ID hose that Motive uses. I wanted to stay consistent with my other Motive adapters and also set it up for use with the Motive quick disconnect, so I elected to remove the 1/8" BSP to Nitto "Hi Cupla" fitting that comes installed on the CTA 3933 with a 1/8" BSPT to 8mm barb fitting. Note that BSP = straight and BSPT = tapered, but this didn't prove to be an issue. I tried and could not find a 1/8" BSP to 8mm or 5/16" barb adapter. Info I found online indicates that BSPT male into BSP female should work just fine.
This is the specific 1/8" BSPT to 8mm barb adapter that I purchased: https://www.amazon.com/dp/B0DPKZ7D7X
I would note that the original Nitto fitting has some sealant on the threads, and you'll want to thoroughly clean that out of the female threads on the CTA 3933 adapter before putting a new fitting on. That stuff could end up in your brake or clutch system.
