They look to have a better shape...more hook. I personally think that transfer shape has lots to do with performance.

Anytime a fluid is flowing through a vessel and you add volume (think cross sectional area) to the vessel, you decrease pressure. Velocity follows suit. You then need to increase the pressure to increase velocity. This tells me 2 things...the upper transfers time area will have a bigger impact on velocity with the larger covers. This may be why the 562 crank is stuffed.
My thoughts exactly..

OK.......

Back to the 555.

I think the transfer covers are gonna make a big difference.

Oh........and Andre. I know I'll lose in the peeing contest. At my age I'm just happy when I miss my feet.

Randy do you think the transfer covers would make a difference on a stock saw or just the ported one? Also what is the part # on those you sent Brad? Thanks

From January......

Sawtroll was the one that kept saying his understanding was that STIHL bought AT tech, but also said he doesn't have any documentation to prove it. He would say this everytime, so eventually people are gonna take that and spread it all over the internet as fact. That's how rumors get started, especially when the source is an from intellect like Nikko. It's dangerous being smart and making statements w/o facts. People tend to trust that information because they figure the source is good.

Bingo. I think the larger transfer covers and crank stuffers work hand in hand. The 562XP covers did help improve performance, but I think the stuffers will make a noticeable difference as well when I swap this topend onto the 2260 next week.
