this guy wanna know if there got other trick instead of pinching the sleeve...
my experience..i have pinching about 3 -4 sleeve. yes the piston will get very tight on the sleeve but the compression is not. when pinching the sleeve is not 100% perfect circle anymore. when piston compress, some of the consumption gas can flow between the piston/sleeve..
the best other trick is, try to use other/different used piston or sleeve. for example my STS piston have wore out. so i use Hyper 8 port piston on my STS sleeve and now it is very tight like new one. i have to break in once more. and the performance is not bad..
