Hello, and a happy new year.
Would somebody maybe like som pictures of the 564xp? Well here they are.
More pictures to come.
brand new saw not started by me.
Specs: bore: 48mm
Basegasket: paper 0.5mm
Squish with gasket 0.85
Ex: 102*

The plan is to increase compression and port it.

Intake coil/computer package.

Plan is to delete base gasket, port to Ex:100 Tr:115 In:78.
If it runs bad i can lover the jug and put som epoxy in intake.
Some rough casting.
And the plating can flake so be careful when somebody tinkers with theese.

Your welcome. Dont know if this saw is available in US yet. Im from Norway.

Very easy to work on, coil etc sits to the right side of saw next to intake. Looks like Huaqvarna tries to make a better produkt here. No plates on the transfer.
Muffler is more open than older 550/560 saws. So i will just open it up under the mest for now. The plate inside the muffler does not go all the way trough. It opens up inside.

Looks like a tsumura bar under the Husqvarna paint.

Thanks for everything. So this is a strato EFI engine, unlike the MS500I. That is definitely a Tsumura bar, which is interesting because all the X tough light I’ve seen were Sugihara.

I have seen sugi too. But maybe because og availability?
I hav run it for half a tank after porting and i think its ok for a 60cc saw. Feels more torque than the old 560 wich i can Compare with.
Will update on the performance when the ovner og the saw has 15-20tanks on it.

Hey, first impression is good. Easy to work on fired up after 4 pulls in -10celsius. Feel like Husqvarna is at least trying to make a great product here. Was as i said a little coarse casting in transfer, exhaust and stratoes. And plating flakes off easy.Feels very strong in 10inch seasoned oak. The owner is on firewood duty these days so expect he will tell soon.

Thanks for sharing. Sure wish it would have an in board clutch.

I get it, but I'm so used to the outboard style that it's nothing. The brake parts all in the clutch cover sure is nice too.

Yea I’m used to it too and having the brake parts in the cover is nice. I just prefer the inboard clutch for ease of sprocket maintenance and changes. And getting bar and chain off. It’s not a big deal just a preference. Don’t matter I’m getting one anyway

And plating flakes off easy.

?!?!

?!?!

I think he means when modifying the ports.
