So I just bought an 02 cr250 and it kicks fine, idles great and everything, but wont open up when revving or riding. You can see when revving it, the RC valve isnt opening the powervalve. I have checked the RC motor by applying 12vdc to both the open and closed side, both operate normally and when idling the valve stays closed just fine. The cables are adjusted properly. I looked at all my wires and they look fine, I am not sure where else to go here. Any help would be greatly appreciated. Thank you.
