I am installing a Koso rx-1n gauge on my bike (hopefully this weekend) and need adapters for both the oil and water temperature sensors. Unfortunately I have no idea what size I need and haven't been able to turn up any promising results from searching the internet and svrider. Also, Koso has no idea what size I need either. Any help would be appreciated. I think the water temperature adapter might be 26mm but idk about the oil gallery plug. Thank you.
