This is simply a comparison of the squish found for OEM 346xp cylinder, Hyway 45mm cylinder kit, Kafar ebay kit 44.3 and the UK ebay kit 44.3.

OEM is definitely tightest squish, what I would consider a little tighter than normal for stock....at .034" This will likely generate the most compression stock.

Eventually I'll have all 5 (including an original 45mm oem) of these cylinders on saws and compare all of them. Lots of people say OEM 346xp is best, and after looking at these, thats tough to argue with. at $105 shipped, its a nice value. I have a sweetspot for the hyway cylinder, but I also think the other 2 I can get to run relatively equivalent to oem w/ some port work. We'll see! Enjoy the vid!
