Doing a build on a 394xp and thought since I have a near new crank from a Jonsered 2095 and are supposed to be the same I find when setting the squish the piston on a stock OEM cylinder seems to be about 25 thou to short in the stroke- don't mind shaving more off the bottom of the cylinder because I do have the setup to do it but was concerned if this would make any difference to how well she runs.
