Hi, I’m looking for a cold start valve from the accessory market for an Aprilia Roller SR50 Motard METCA41 from 2018. Somehow I won’t really find it, at least I’m unsure. Carburetor is a Dellorto PHVA 17.5 and the cold star valve has the square plug. Can I just take any one out of the net or is there no 100% matching from the accessory at all? Thank you for your information.
