"Huskvarna" 272xp Stocker vs ZIPPED 272XP

So here we take a looksee at the differential between a completely stock 272xp and a low hour Psy-Ko Zippkitted 268 converted , via an OEM 52mm bore topend assembly, to the same 72.2 cc - 52mm Bore x 34mm stroke.
The used 272xp is bone stock but not really clapped out. Pretty good compression with the starter rope method of checking.
Showing, "kind of", a differential between a 272 in factory trim, a Zipped 272xp, and then the Zipped 272xp sporting a K&N with a nice velocity stack.
Yes, there was an OOOPPPPs on my part. The 272s were factory rated @5.2 HP not the 5.4HP I errantly stated - thinking about the 50mm bore 372s there - My apologizes.
Regardless, the Zipped 272xp runs much better than the stocker with the HD filter system and runs even better yet with the K&N.
Timed runs as follows:
Bone Stock 272xp running ~ 13,080 and struggling 13.03 down and 12.62 up
Zipped 272xp with HD filter ~ 13,680 still missing 10.17 down and 10.01 up
Zipped 272xp with K&N/stack running ~ 13,500 went 9.78 down and 8.78 up
I am well pleased with the 268/272 hybrid's showing here.
It's important to note that the 268/272 has new seals as well as a new topend assembly. It doesn't have a lot of run time on it and performs a little better each time I use it.
Tuned with the Psy-Ko zippkit work a work saw application but it doesn't have my Patented "Torque Tweak" installed.
As stated, the 272xp may or may not be available. It will take a communiqué.
I'm currently available for custom saw modifications. If you are interested, please shoot me an email.
