Husqvarna L77 ported vs 480CD

Same bar and chain, same wood and same CC.
480cd is stock, L77 is ported.

Good display of power there. Good job.

Thanks!

Great old saws👍🏻 I just picked up a 480cd, it has a ton of compression. I’m looking forward to tearing into it.

[@mtbbike92]

Thanks! Upload a video if that 480 is done.

[@johnmalatesta751]

77 is a torque monster 😅

[@TheJonsberg]

Just have to love the sound of a ported Husqvarna chainsaw, nicely done 😁👍💪

[@mtbbike92]

L77 has a muffler mod too

What's max RPM on 480cd?

[@mtbbike92]

I tuned to 11000 rpm without load.

My 480 is apart on the bench now. Ill be starting cylinder work on it tomorrow.

[@fearghalmorrissey2601]

Are you going to port the 480?

[@mtbbike92]

I don't know yet. Maybe yes.

@@mtbbike92 it is definitely worth doing, gas flowing the exhaust better It really frees the engine up 👍🏻

A piece of advice, never just hack away at the ports with a dremel by eye. That is the fastest way to junk a cylinder. Always use engineers dye. That way you have a clear indication what material is required to be removed to give a far smoother transition of the gases.
