I have a mki. Ive updated it to AT12 carb, muff mod. No porting at all. Want to say that it runs exceptionally well. Buddy recently purchased a mkii. It also runs exceptionally. I still prefer ergos of my saw.
Them saws run real good. Do you change anything on the strato,s when you porting these or just work on the regular intake and transfers. I've never ported a strato so not sure how to go about it.
They both run awesome. Maybe its just me, but the MKII sounds like it holds RPMs a little better in the cut. Maybe they did something different with the coil/autotune stuff?? Im no expert one these 5 series by any means , just a guess. What do you think, Shaun?
They took out the rev boost feature for the MK2 which might show up trimming small stuff, but no other changes from what I could tell. I've made a small change in the port timing numbers which helps it hold a little more RPM in the cut.

Nice saws ! I see you have the outer dogs on you saws . Can you please tell my where to locate these . Thanks
They are modified Husqvarna 560 (small mount 562) spikes.
Flywheel has double magnets so it’s reading twice doubling rpms

Strato saws run a lot less blowdown than you would see on traditional saws.
Question, will the 20 inch bar on the 550xp work on the 550xp mark II ???
Yes.

What do you charge for a complete port tune on a mark2 550
Did you put 562 dogs on the clutch cover?
I put the 560 (small mount 562) spikes on it.
Ciao amico che differenza hai trovato da 550 vs 550 Mark 2 grazie
They changed many things, too much to list, but the port timing was the same.
Those 5 series are hella impressive
Like 👏👏👏
Man I miss my old Mk1 like I miss my first truck. What a workhorse saw, all about the bubble baby. Mk2 waste of time.
Nah mk2 is great.
