Itīs an average weight for that size valve,so Iīm happy.Personally,I prefer a material that is "bullet proof" and can withstand extreme temps rather than a light valve of maybe lesser quality.Thereīs a spring for everything nowadays.I donīt think I would notice the difference in acceleration or perhaps wear if the valve was 10 or 20 grams lighter.I would rather save weight elsewhere like on the rods and pistons.
