I've searched forums but can't seem to find the information I'm looking for. If there is a thread please link it.

I have a 2GA GSX w/ABS. I don't want to delete the ABS but I need a new prop valve. I’ve done some research on it and seen the EVO and the 1G valves look like it but they have different braking biases, PSI, and possibly threads? I'm pretty sure I have a 1G one installed after my first one went bad, now the 1g has gone bad as well. I'm looking for a replacement but I am not sure what to be looking for. I don’t want to bend/reconfigure new brake lines so I’m hoping for an OE option.

I see a lot on eBay but they say things like d21, d16, d2 with no clue what this means. Should I just order a couple eBay ones and let them run their course?

Did the second go bad because it's 1g? Should I only go for 2g ones? Is the Evo spring stiffer in the prop valve compared to the 2g?
