Vulcan 1500 Valve Lapping

Let's get to valve lapping on the 1500 Vulcan re-build. Here's the before on the front cylinder.


Here are the valve seals. They have to go.

Pry 'em off and throw them away.

Get the lapping compound.

Put a light coat on the valve sealing area.


Put the valve in to the hole it came out of and twist it back and forth, back and forth.

When you clean off the compound and see a nice even gray line in the seat, you're good to go.

You need a nice line on the valve, too.

Repeat that three more times and the front is done, but be sure to wash everything to get the compound off before you build the motor.

Repeat that 4 more times and the rear is done, too.
