How long does it take to install valve springs
How many hrs does it take to install hd valve springs? Is it easier to drop the motor or do it on the bike?

Unless you make a setup to pump compressed air into the cylinder, you won't be doing it on the bike....
Besides, it would be a huge PITA trying to fit the keepers with the head on the bike, imo...
I thought you were changing the head gasket anyway??

How are you keeping the valves from dropping?

My friend has a air fitting with spark plug threads that allows you to compress the cylinder. That way the valves won't fall into the head once the keeper's removed.
Also, I don't know that it's worth the hassle putting on a thicker head gasket. However, if I'm removing the motor, maybe it will be pretty easy to change out the head gasket.

I'd like to see the tool you use to compress the springs with the head on.
air in the spark hole is simple compressing the spring and getting keepers out and back in?

all the air does is hold the valve against the seat. I have always removed the head. I have never tried using air, But that's just me.

haven't done it that way on a bike, its always too simple to pull the motor or head.
But on LS1 based cars they make a tool for it, thats the only time i've done springs with the heads on the motor in the car.
