I am rebuilding my motor and i have some small imperfections, for example I didnt use the locating pin for the shift drum, i don't have the bearing stopper plate that goes to the shaft behind the clutch, when i shift gears, the gap between the pins and the shift shaft changes whenever i switch gear. in first gear the gaps are equal but when i switch gear it usually gets more uneven. Also, does it really matter which way the washers and cerclips go on the mainshaft and countershaft? if they face inwards or outwards? This is my first engine build btw.
