Has anyone put a Boyeseen rad valve on their CRM Mk2 or know if you can do it if so do you know which part number it is.
Boyeseen website does not show it for CRM's but i would expect the CR's to be the same.
Any help.

I believe you can use the one for the CR250 1989 (which covers other years as well) but you need to take the brass oil tube from the CRM original and insert it into the Rad valve. You need to get a good seal on this.

I think the rad valve has a built in carb rubber which will prob be the wrong size and angle for a CRM. CR250 rubber for that year is for a 38mm carb

Better off with Boyesen petals for your block or a V-force for that year CRM
