This is a new thread from the "aftermarket cylinder quality" thread - https://opeforum.com/threads/aftermarket-cylinder-quality.26470/
(pics are uploading in a few min)
I figured it might be better to start a new discussion. Lots of pictures below text.
I don't have timing numbers yet but I think the pics will show some interesting differences. Right off the bat, the OEM cylinder is noticeably heavier (see scale). The cooling fins are thicker....which I thought I read it's the aftermarket stuff that had thicker cooling fins not the oem. Anyway, there is also an extra cooling fin on the oem near the exhaust port.
The aftermarket transfers are very different. The lowers on the titan cylinder don't have near as much of a venturi type of shape and are cut deeper by a good bit. Hopefully the pics show that. Curious what others think.
The piston on the OEM is way nicer and lighter (see scale). It's not from the pin, both pins weigh the exact same. Also the OEM piston is nicely beveled all over, the titan piston has many sharp edges. I actually cut the hell out of my finger when testing pin tightness on the titan.
You can see a defined and symmetrical line of plating in the ports of the oem cylinder. On the titanikel the line is not nearly as defined or symmetrical. Hard to tell in some spots how far it goes into the port....
Anyway, I am going to use the titanikel on my friends saw I am building, and the oem on my saw (he didn't want to pony up for oem)
